                     RESEARCH REPORTING  SERIES
Research reports of the Office of Research and Development,
U.S. Environmental Protection Agency,  have been grouped into
five series.  These five broad categories were established to
facilitate further development and application of environmental
technology.  Elimination of traditional  grouping was consciously
planned to foster technology transfer  and a maximum interface in
related fields.  The five series are:

           1.  Environmental Health Effects Research
           2.  Environmental Protection  Technology
           3.  Ecological Research
           4.  Environmental Monitoring
           5.  Socioeconomic Environmental Studies

This report has beqn assigned tg the'ENVIRONMENTAL PROTECTION
TECHNOLOGY series.  This series describes research performed
to develop and demonstrate instrumentation, equipment and
methodology to repair of ^prevent, environmental degradation from
point and non-point sources of pollution.  This work provides the
new or improved technology required for  the control and treatment
of pollution sources to meet environmental quality standards.

                       ABSTRACT

This report presents a conceptual design and an
economic evaluation of a 9070 metric ton per day
plant for the chemical removal of pyritic sulfur
from coal.

The design is based on removal of 95% of the pyritic
sulfur from Lower Kittanning coal.  The product coal
should meet present air quality regulations for fuel
combustion operations as regards total sulfur content.

All supporting facilities are included for a self-
sufficient operating complex with purchased water and
power.  The process engineering is complete through a
capital cost estimate.  Computer augmented studies are
included for the material and energy balances, selection
of the reactor systems, monitoring of operating para-
meters and economic sensitivity studies of process
alternatives.

This report was submitted in fulfillment of Contract
No. 68-02-1302, by the Contract Projects and Process
Engineering Departments, Michigan Division, Dow Chemical
U.S.A., under the sponsorship of the Environmental
Protection Agency.  Work was completed in October 1974.

                  1.0  CONCLUSIONS

The design in this report (Chapter 4.0) is based on data
from bench scale work by TRW, Inc./ wherein technical feas-
ibility was reported in EPA-R2-73-173a and 173b, February
1973   .  The TRW work has been augmented by limited labora-
tory data obtained by the contractor  (Section 4.4), on
preliminary recommendations from vendors without actual
testing, and on the best engineering judgment available
within the time constraints imposed.

The present study indicates potential technological and
economic feasibility for a large commercial scale plant
contingent on successful completion of projected pilot
plant development.

Capital and operating costs per ton of product coal are
favorable with respect to other known processes  (Section
5.3) for meeting air quality regulations when burning coals
of comparable sulfur content.  Capital and operating costs
would be more favorable if this process were integrated
with large, coal-fired, power generating facilities which
would already include raw coal handling, crushing and pulver-
izing, and handling of the pulverized coal  (Section 6.3).

-------
                2.0  RECOMMENDATIONS

Listed below are recommendations for developmental efforts
that would permit more precise definition of the present
design (2.1), suggested areas for research that would appear
to hold promise in the development of a revised, "second
generation" process or in the understanding and refinement
of the present process  (2.2), and recommendations based on
economic factors that could have a significant effect on
the process  (2.3).   Sections of this report having a bear-
ing on the recommendations are cited in parentheses.

Further discussion is given for this subject matter in other
sections of the report, viz. 3.3.3 On-Going Development de-
scribes a number of contracts where some of this work is
already underway and 3.3.4 New Areas of Examination delin-
eates where in the report other discussion is given relat-
ing to these recommendations.
2.1  FURTHER DEVELOPMENT OF PRESENT DESIGN

2.1.1     Bench Scale and Mini-Plants
Additional laboratory data should be obtained in the areas
listed below in order to improve the quality of output from
kinetics and design calculations:

     Iron sulfate solution and solid phase properties and
     chemistry, e.g., density, viscosity, heat capacity,
     conditions of precipitate formation, identification
     of the solid phases  (Chapter 4.0, 7.5).

-------
The elimination or depression of elemental sulfur formation
in the reaction steps should be studied in continuous pyrite
leaching.  Sulfur formation is counterproductive and its
removal is costly (6.2.2, 7.5).

Technically feasible process steps need to be developed for
removal of the proper ratio of ferrous and ferric sulfates
and for the recovery of values for sale or for recycling
back into the process.  Potential values recoverable from
the iron sulfates waste stream include iron and alkaline
sulfates, iron oxides, extracted sulfuric acid, sulfur
dioxide and subsequent products such as sulfuric acid and
elemental sulfur.  Waste sulfate liquor could be incorpor-
ated in a gravity separation step preceding the Chemical
Processing sectors to separate very heavy mineral fractions
and partially react with alkaline components.  The most
promising bench scale iron sulfates removal process should
be further proved out in continuous bench scale equipment
in a mini-plant arrangement (4.4.2.3, 6.2.2, 7.5).
2.1.2     Pilot Plant
Data from continuous operation of a pilot plant are neces-
sary to determine the compositions of the many recycle
streams.  Optimization of the following items needs to
precede the final design of the commercial scale plant.

     1.   Liquid to solids ratio in the mixing and reaction.
          steps for various pyrite contents in coal.

     2.   Degree of pyrite conversion attainable in the
          mixing and post-mixing steps at atmospheric
                           -4-

-------
     pressure vs the reaction steps at higher pressure
     and temperature (4.2, 7.5).

3.    The effects and interactions of pyrite feed and
     product assay with (1) and  (2) above and  (7),  (8)
     and (10) below, as well as with overall capital
     and operating cost relationships  (6.4, 7.5).

4.    Reactor geometry and configurations  (4.2.3).

5.    Mesh size of coal vs FeS2 removal efficiency and
     costs for coal filtration and handling as well as
     changes in overall control parameters, e.g. time
     and temperature (4.4.2.1, 7.5).

6.    Gravity separation of low carbon content refuse
     from the ground coal near the mixing step  (6.4,
     7.5, 10.7.3).

7.    Reaction and regeneration parameters  (temperature,
     pressure, concentration) to best take advantage
     of kinetics  (4.2.3, 7.5).

8.    Careful definition of the ferric ion and oxygen
     stoichiometry during the various parts of the
     leach reaction.  Single pass and multi-point
     oxygen introduction vs pumped recirculation of
     oxygen in contact with solution  (4.4.2.1, 7.5).

9.    Safe operating parameters for oxygen in contact
     with coal fines and with possible solvent
     carryover.
                      -5-

-------
10.  Sulfuric acid control level at the beginning of
     the reaction process to keep the best stoichiometric
     balance for the reaction and at the end to prevent
     precipitation of ferric compounds  (4.2, 7.5, 10.4).

11.  Determination of desirable start-up conditions
     necessary to prevent incomplete sulfur removal
     before process equilibrium is attained (7.5).

12.  Type of liquid-solids separation equipment:  Set-
     tlers, cyclones, centrifuges, or various types of
     filters — drum, disc, flat bed or belt (4.5.4).

13.  Efficacy of using chemical additives for wetting,
     settling, filtering and dewatering coal fines and
     for foam control (4.4).

14.  Filter operation:  dewatering alone, dewatering and
     washing, or dewatering, washing and steam purge
     (4.1).

15.  Mass transfer operations:  single stage vs multi-
     stage solvent extraction and water washing  (4.1).

16.  Selection of solvent and its operating temperature,
     e.g. naphtha, toluene or other hydrocarbon or
     chlorinated hydrocarbon solvents below or above
     the melting point of sulfur  (4.1, 4.4.2.1).

17.  Elemental sulfur recovery step:  separation of
     solvent by distillation, filtration or other
     means (4.1) .
                      ~6 —

-------
     18.   Feasibility and degree of iron sulfate separation
          by crystallization and of H-SO. extraction from
          the iron sulfates waste using acetone or other
          solvent (4.4.2.3).

     19.   Definition as well as economic impact of product
          coal specifications:  sulfur forms, ash, moisture,
          chlorides, and, if pellets are desired, their
          size, strength, and weatherability (6.2, 6.3, 7.5).

     20.   Binder selection, e.g. lignin sulfonate, coal tar
          pitch, styrene - butadiene latex plus clay, and
          others.  Each has advantages (4.4.2.4, 6.4).

     21.   Energy conservation.  Minimum usage of steam,
          compressed air, process water make-up and electric
          power  (4.7, 4.8.3).

     22.   Materials of construction, especially with respect
          to chloride cracking of stainless steels  (4.3).

     23.   Manpower requirements: process, services, admin-
          istration  (5.1.2, 10.7).

     24.   Solvent losses by reaction or absorption on a
          variety of coals and by reaction with molten
          sulfur.
2.1.3     Commercial Scale Plant
Integration of chemical desulfurization of coal with large
power generation plants near the coal fields would effect
                         -7-

-------
substantial economies  in  capital  and  operating  costs  as
given below  (6.3).

     1.   Existing  facilities would be utilized for receiv-
          ing, storing, handling, grinding,  and pulverizing
          the feed  coal.

     2.   Finished  coal drying, compacting,  storing,  and
          loading would be minimized.  The warm, damp coal
          from the  final  filtration could be fed directly
          to the pulverized coal  burners.

     3.   The steam generation plant  would be eliminated.
          Low pressure steam would be available from  the
          utility at bulk rates.

     4.   Cooling water requirements  for chemical desulfur-
          ization would be minor  compared to those of the
          parent power plant.

     5.   The electrical  substation would be eliminated for
          the desulfurization plant.

     6.   Administration, maintenance and overhead costs
          would be  minimized due  to sharing.

     7.   Site purchase would be  eliminated  and site  develop-
          ment costs reduced as a developed  site would exist.

Lower cost conventional methods of coal preparation should
be utilized to their limit on ground  coal.   Chemical  desul-
furization should be used to the  extent needed  to provide

-------
clean fuel and minimize the amount of coal disposed of
in the refuse  (6.3, 10.7.3).  Advantage should be taken of
current new technology for drying and shipping coal fines
where on-site product use is not possible.  This would
include pipelining coal slurries and shipment of bulk coal
fines in closed hopper cars or in open cars protected with an
artificially induced crust for weather protection  (4.4.2.4).
2.2  RESEARCH FOR A "SECOND GENERATION" PROCESS

In addition to the above developments, a more basic research
program should be conducted to provide fundamental chemistry
and engineering data to permit testing and incorporation of
new ideas that could lead to changes and improvements outside
the scope of the present designs  (4.4, 7.5).
2.2.1     Coal Handling and Leaching
The chemistry, kinetics and thermodynamics of leaching and
regeneration for high, medium and low levels of iron sul-
fides in coals of various composition and top size need to
be better understood.  In addition to those parameters men-
tioned in the above section, the following need to be
studied and optimized:   elimination of elemental sulfur
formation by control of solution emf and pH, pretreatment
of coal with heat or chemicals to minimize reaction time and
maximize FeS2 conversion, nature of any inhibiting or cata-
lytic effect of accumulated impurities or additives, use of
supplemental oxidants to assist in the reaction when the
FeS2 is largely depleted, very high pressure leach solution
regeneration external to an atmospheric leach system.
                           -9-

-------
2.2.2     Extraction and Washing
If the deposition of elemental sulfur cannot be eliminated
from the leach reaction, laboratory work should be performed
to determine how the sulfur is physically dispersed in the
coal, and a wide variety of solvents and physical conditions
should be studied to determine how best to remove the
elemental sulfur.  During this step it may be feasible to
effect some reduction of organic sulfur at minimum extra
cost.  Also, in the event that the use of chlorinated sol-
vents becomes attractive, the tolerable level of chloride
ion in the product needs to be established to assure that
the coal product is no more corrosive in use than native
coal.

The contribution of wetting agents to facilitate partition-
ing of solvent, coal, and water should be studied, and
agents to further solubilize sulfates during washing should
be tried.  This might be done in conjunction with the study
of supplemental oxidizing agents.  Supplemental ferric chlo-
ride or ferric nitrate could provide a more soluble ion that
would wash out more readily, and post-leach oxidation of the
elemental sulfur might eliminate it or make it possible to
utilize smaller sulfur recovery equipment.
2.3  ECONOMIC FACTORS

All of the foregoing would need to be judged from a tech-
nical and an economic basis.  There are a number of factors
that are almost purely economic or business related that
could have a significant effect on successful advancement
of chemical desulfurization.  From the studies reported
in Chapters 5.0 and 6.0 these are as follows:
                           -10-

-------
1.    The level of interest in chemical desulfurization
     of coal by coal producers, utility plants and
     others should be determined.   Pricing and market
     considerations for pyrite-free coal need to be
     clarified apace with the development of desulfur-
     ization.  The contribution that this technology
     could make to other sulfur dioxide abatement
     programs should be explored,  e.g. alkaline earth
     materials could be incorporated in the compacting
     step to provide feed for a limestone-injection
     type of boiler.

2.    A number of hypothetical installations at exist-
     ing utility or coal preparation plants should
     be estimated to determine the costs that would
     be allocated for the Coal Handling portions of
     this process by the respective industries  (6.2.1).

3.    The Chemical Processing portions of this design
     should be updated by a process engineering group
     to reflect the latest TRW, Inc., technological
     developments as applied to various coals amenable
     to chemical desulfurization  (6.2.2).

4.    Concurrent with the above three recommendations
     a business-related study should be made incorpo-
     rating reliable projections of cost indexes and
     prices.  This study should include a top manage-
     ment perspective for a business having annual
     sales and an investment in excess of $100 million.
     It should also include a refined estimate of work
     assignments, labor costs and optimum design to
     maximize the number of production days per
     year that can be reliably used.
                       -11-

-------
                  3 . 0  INTRODUCTION

Coal is the largest energy resource available for immediate
exploitation in the United States.  The annual consumption
of coal is expected to triple in the next 30 years.  Accom-
panying this growth will be a depletion of low-sulfur coals
and increased need to use high-sulfur coals.  Sulfur dioxide
from the combustion of sulfur bearing coals is already the
largest stationary source contributor to air pollution.  The
utilization of coal as a readily available energy resource
will be blocked unless suitable means for controlling sul-
fur dioxide can be developed.

Removing the sulfur from coal prior to combustion is poten-
tially the most efficient control method from the standpoint
of logistics and materials handling technology.  Conven-
tional coal preparation processes utilize crushing, screen-
ing and gravity separation to remove shale and pyrites,
essentially FeS?, from coal.  Only a relatively small amount
of low pyrite coal can be obtained by gravity separation.
The bulk of the product has pyrites in the low to middle
range, and the high sulfur and ash portion is discharged as
refuse.  As increasingly strict air quality control specifi-
cations are developed and supplies of coals amenable to good
cleaning via conventional methods are diminished, it will be
necessary to more completely remove pyrites from a larger
fraction of the coal treated.
A chemical leach process has been developed by TRW, Inc. ,
and described in report No. EPA- R2-7 3-17 3a, February 1973 (
prepared for the Environmental Protection Agency under
Contract No. EHSD 71-7.

3.1  SCOPE AND PURPOSE

The Dow Chemical Company was awarded the present contract to
utilize the above report, review a number of process flow
schemes and variations, develop a conceptual design for a
9070 metric tons  (10,000 short tons) of coal product per day
process plant  (with all supporting facilities) to extract
95% of the pyritic sulfur from a Lower Kittanning coal,
submit a detailed cost estimate of the plant capital re-
quirements, and perform economic sensitivity analyses of
variations in the process.

This design and these analyses Will provide a basis for
directing the development of this chemical desulfurization
method towards the most cost-effective approach for further
pilot operation and commercial scale application.

3.2  PROCESS DESCRIPTION

3.2.1     Reaction Chemistry
The chemistry of the coal depyritization process described
in the TRW, Inc., report    is defined by the following
equations :

3.2.2     Chemical Desulfurization
The process presented in the TRW, Inc., report    is
described below.
The ground -149 micron  (-100 mesh) coal is wetted with hot
recycled aqueous ferric and ferrous sulfate in a mixing tank.
The coal slurry is pumped batchwise to one of ten closed
reactor vessels and oxygen is introduced.  The temperature
increases due to the heat of reaction and regeneration, and
the system pressure is allowed to increase to above the
vapor pressure of the solution.  After about eight hours
the reactor is drained and the coal is transferred to a
settling tank and filtered to remove the aqueous sulfate
solution which is evaporated to separate iron sulfate.
Most of the sulfate solution is recycled to the mixer and
the coal is given a displacement wash and conveyed to the
extraction and washing section.
                           -15-

-------
In an agitated extraction vessel  the  coal  is  contacted with
naphtha to extract elemental  sulfur.   The  coal  is  filtered
and the solvent and  aqueous layers  separated  by decanting.

Sulfur is precipitated  from the solvent  by cooling and is re-
covered by filtration.   The coal  is conveyed  to an agitated
wash tank, then filtered and  fed  to a variable  pitch  screw
conveyor for vacuum  drying and movement  to product storage.
3.3  PROCESS DEVELOPMENT

This report represents one phase of a very complete develop-
mental effort.  The sections that follow describe the
significant contributions of the prior effort by TRW, Inc.,
the modifications incorporated in the present design, other
concurrent and on-going efforts, and areas which hold promise
for still other improvements.
3.3.1     Prior Development and Design
The complete chronology of the development of the ferric
sulfate leach process is given in the TRW, Inc., final report
for contract EHSD 71-7   .  A brief summary of the develop-
ment preceding the TRW process design will be helpful in
placing the current Dow Chemical Company conceptual design
in the proper perspective in the development sequence.
The ferric ion process for chemical removal of pyritic sul-
fur from coal  (Meyers Process) was demonstrated to be capable
of removing essentially all of the pyritic sulfur from sam-
ples of four Illinois and 'Pennsylvania coals representing
                           -16-

-------
major U.S. coal beds.  Kinetic equations were developed for
extraction of 100 mesh topsize Lower Kittanning coal with
3 to 10 wt% ferric ion at ambient pressures and a slurry
reflux temperature of 102°C.  Ferric sulfate was chosen
over other ferric compounds because of its ease of removal
from the treated coal and its reduced corrosion of process
equipment.  Initial experimentation was conducted with 100
gram coal samples and later work involved approximately 500
gram samples.  Leaching temperature, leacher ferric ion to
total iron ratio, coal particle top size, and pyrite con-
centration in the coal were identified as the major param-
eters affecting pyritic sulfur leaching rate.

Other parameters investigated were:  solids to liquid ratio,
residence time in each process step, reagent purity, coal
weathering, reaction pressure, ferrous ion concentration,
oxygen partial pressure, liquid-gas mixing and liquid to gas
ratio, and filter washing.

From a computer fit of the extensive data obtained, an equa-
tion for the rate of removal of pyrite was generated:

          -dWp/dt = KTWp2Y2                                 (6)
                     LI

where  KT = reaction rate constant, a function of tempera-
        Li
            ture and coal particle  size, 0.15 when t is in
            hours
       Wp = pyrite concentration, wt. %  in coal at time t'
       Y  = ferric ion to total iron ratio  at  time  t.   A
            ratio of F
            desirable.
ratio of Fe  /Fe close to 1.0 was found to be
                            -17-

-------
Smooth curves back calculated  for -100 mesh Lower Kittanning
coal at 102°C indicated that to remove 90% of the pyritic
sulfur, leaving the coal with  about 1% total sulfur, would
require an eight hour leach with continuously renewed ferric
sulfate.

It was apparent from the data  that improvement in the rate
could be obtained by employing higher temperatures and pres-
sures.  It was found that the  temperature dependence of the
reaction rate constant could be expressed as:
          KL = AL  exp(-EL/RT)                              (7)

where     AT = 2 x 10 3   (hr)"1  (Wp)'1
           LI
          ET = 7 kcal/gm mole
           LI

The early data on the temperature dependence of reaction
rate were scattered and the equation was based on just the
two sets of data at 70° and 102 °C.  Subsequent data for the
leaching process at temperatures above 102 °C confirmed the
constants chosen.
In the second phase of the process, the regeneration of the
ferric solution by oxygen, the important parameters in the
rate of regeneration were found to be the partial pressure
of oxygen and the concentration of ferrous ion, which is in
agreement with literature data on the subject.  Analysis of
the data gave a rate expression:

          -dF/dt  =  KDPF2                                  (8)
                      K
                        -18-

-------
where  KR  =  AR exp (-ER/RT), (40.2 x 106)exp(-13,200/RT)
                        = 1.836 liter/(gm mole) (atm) (hr)at 120°C
       AR  =  6.7 x 10  liter/(gm mole) (atm) (min)
       ER  =  13.2 kcal/gm mole
       F   =  concentration of ferrous iron, gm mole/liter
       P   =  oxygen partial pressure, atm

These expressions were found valid as long as sufficient
agitation was provided to prevent liquid-gas separation.
Low flow rates gave reaction rates much lower than the
high agitation runs.

Comparison of the rates of the leaching and regeneration
reactions indicated that regeneration is faster, so that a
reactor with simultaneous leaching and regeneration looked
favorable.  Limited experience showed 84% pyrite removal in
a 2-hour extraction of -100 mesh Lower Kittanning coal at
130°C, with simultaneous regeneration of ferric ion by oxy-
gen.  Further work is in progress.

A conceptual process design was prepared by TRW based on 100
short tons of coal feed  (dry basis) per hour.  The coal was
assumed to have 3.2% pyritic sulfur and to consume a negligi-
ble amount of ferric ion in oxidative ion reactions.  A
number of alternative processing methods and parameters were
tested on preliminary engineering designs and various eco-
nomic trade-offs were taken into consideration.  A process
baseline design was developed  and a process flow diagram
and material balance presented.  A brief description of the
process steps and equipment was given.  A capital estimate
was made for the major process equipment, and the process
costs were estimated.

3.3.2     Current Modifications
This report presents a complete process engineering design.
The TRW report    may be consulted for details of the earlier
conceptual design.  At the beginning of the present project
the TRW design was carefully evaluated.  The final Dow de-
sign contains a number of deletions, additions and modifi-
cations that were based on judgment, practicality and
laboratory tests that evolved as the design progressed.  In
addition, there were modifications in materials of construc-
tion and auxiliary equipment and a more complete definition
of operating conditions, material and energy balance, man-
power, and all pertinent design considerations.
3.3.3     On-Going Development
The Control Systems Laboratory of the Environmental Protec-
tion Agency has sponsored the following developmental efforts
by TRW, Inc., pertaining to the chemical leach process:

Contract 68-02-0647, "Applicability of the Meyers Process
for Chemical Desulfurization of Coal:  Initial Survey of
                (2)
Fifteen Coals,"v  .  Final report issued April 1974.

Demonstration of the applicability of the Meyers process on
at least thirty five samples of coal selected to meet stated
criteria.  Careful analytical results obtained for unpro-
cessed coal and coal subjected to chemical desulfurization
and to float and sink testing.
Contract 68-02-1336, "Bench Scale Development of Processes
for the Chemical Extraction of Pyritic Sulfur from Coal"
In progress.
                           -20-

-------
A follow-on to contract EHSD 71-7   .  Optimization of leach-
ing and regeneration techniques.  Study of methods for
removal of spent leach solution and sulfur from processed
coal.  Evaluations of nonroutine analytical procedures.
Additional bench scale experimentation of pyritic sulfur
removal from larger top-size coals and coals that have
been subjected to various forms of pretreatment.

Contract 68-02-1335, "Pilot Plant Design of a Pyritic
                       (4)
Sulfur Removal Process"   .  Final report in preparation.

Design of a one-half ton per hour pilot-scale unit for batch
and continuous flow capable of total removal of pyritic
sulfur from coal.  Preliminary process engineering design
will include flow diagrams, mass and energy balances, and
the specification of operating conditions, major equipment,
controls, utilities, and construction materials.  These will
be used to develop a detailed process design for the pilot
plant with a capital cost estimate and a scale model of the
process.  A pilot plant test program will be developed.

Modification and incorporation of pertinent technology from
all of the foregoing contracts would be applied to the build-
ing and operating of any such pilot plant to demonstrate,
in continuous operation, the equipment and procedure needs
for scale-up to a commercial sized plant.

In addition to the above EPA funded programs, TRW, Inc., has
initiated an internal business development project to assess
the financial investment opportunities of the chemical
desulfurization process.  This includes the following areas
of interest:
                           -21-

-------
     — Low sulfur steam coal production
     — Low sulfur coking coal production
     — Feed for coal liquefaction

Additionally, the EPA has performed in-house studies to
corroborate and extend the above findings.
3.3.4     Mew Areas of Examination
During the course of the engineering development of the
conceptual design a number of questions presented themselves
suggesting alternatives that were outside the scope of this
contract.  Those that are closely allied to the engineering
and pilot plant design are mentioned in Chapter 4.0, Con-
ceptual Design, in the sections to which they would have
application.  Others that might have a different or less
well-defined application are described 'in Section 4.4,
Laboratory Studies.  Technological or business alternatives
that could be expected to have a considerable economic
impact were incorporated in Chapter 6.0, Process Alternatives
and Their Economics.  Chapter 7.0, Continuous Simulation
Monitoring Program, takes a close look at the process start-
up, chemistry and kinetics, and points out areas where improve-
ments can likely be made in further developing the present
design and in research for a "second generation" process.
3.4  COST BASES

Detailed cost bases are given in chapter 5.0, Process
Economics.  The base case economics were calculated for
the following conditions:

                4.0  CONCEPTUAL DESIGN
The conceptual design presented in this report is based on
data from bench scale work by TRW, Inc., reported in EPA-R2-
73-173a and 173b, February 1973   , augmented by limited
laboratory data by The Dow Chemical Company, on preliminary
recommendations and quotations by vendors without benefit
of actual testing, and on the best engineering judgment
available within time, manpower, and budgetary constraints.
Although the design and selections are preliminary in na-
ture, they provide a reasonable basis for economic
evaluation.
4.1  GENERAL DESCRIPTION

The conceptual design which follows is a complete "grass
roots" complex having four identical chemical process units
for chemical desulfurization of coal, facilities for han-
dling and preparing the feed coal to the process units,
handling the processed coal from the process units, an
oxygen-nitrogen plant, raw material receipt and storage,
and all utility and supporting facilities except power and
water which are assumed to be purchased from a utility
company or a municipality.
4.1.1     Design Bases

The bases used for plant location, site and overall plant
description as well as economics are listed in Sections 3.4
and 5.1.  Some of these are restated and other bases for the
engineering design are given in Tables 1-4.  Table 1 lists
the daily plant capacity and an annual capacity assuming

                         -29-

-------
331 operating days per year or operation about 90% of the
time.  The feed coal specification is listed several ways
in Table 2.  The coal analyses chosen were derived from the
TRW, Inc., report   .  The product coal specification in
Table 3 was developed assuming 95% FeS- removal and a
moisture content attainable by modern drying methods.
Table 4 shows, by source, the amount of sulfur remaining
in the product coal as a percent of the coal leaving the
dryer, dry basis, from Section 10.5.3.

4.1.2     Block Flowsheet
Figure 1 shows the overall process from receipt of raw feed
coal through to product coal including by-product sulfur
and sulfates waste.  With the exception of raw and product
coal handling, which do not involve chemical processing,
each step is described below.
4.1.3     Process Description
The various process steps are described in detail in the
following sub-paragraphs with appropriate figures.
4.1.3.1   Mixing - Coal containing 6.7% -of FeS2  (dry basis)
pulverized to -149 micron, U.S. Sieve Series,  (-100 mesh,
Tyler Standard Sieve Scale Series) is fed to an agitated
mixing vessel operating at atmospheric pressure and having
a 1 hour residence time.  Leach solution  (2.5%  (by weight)
ferrous sulfate, 13.3% ferric sulfate, 0.8% sulfuric acid,
and 83.4% water), returned at 98°C from subsequent process
steps, is fed to the mixing vessel in the ratio of 2 tons
of leach solution per ton of coal.  Of the original FeS2/
14% is converted to ferrous sulfate and elemental sulfur.
See Figure 2.

The solids from mixing are now 94% (by weight) coal, 5.8%
FeS~ and 0.2% elemental sulfur.  The leach solution is now
7.5% ferrous sulfate, 6.2% ferric sulfate, 2.3% sulfuric
acid, 84% water.  A side stream amounting to 31% of the
slurry is fed to the iron sulfate removal step and 64% of
this is subsequently returned from the iron sulfates re-
moval sector described later.  By-product steam from iron
sulfates removal is used to maintain 102°C effluent temper-
ature.  Sulfuric acid, 98% is added to the mixer to make
up for acid which is lost in the iron sulfates waste.

4.1.3.2   Reaction - The slurry from mixing and iron sul-
fates removal is composed of 34% solids and 66% liquid.
The solids are 94% coal, 5.8% FeS2 and 0.2% elemental sul-
fur.  The liquid composition is 6.4% ferrous sulfate, 5.5%
ferric sulfate, 2.8% sulfuric acid and 85.2% water.  This
slurry is fed to reactors in parallel, each having 10
hours of residence time.  See Figure 3.

Oxygen, 99.5%  (by volume), is fed to each reactor through
two spargers near the bottom of the reactors.  The reactors
                    2
operate at 5.6 kg/cm   (80 psia) in the vapor space at the
                   2
top, plus 2.5 kg/cm  (36 psi) hydrostatic head.  Exothermic
heat of reaction raises the temperature of the reactor ef-
fluent to 152°C.  The effluent is composed of 32% solids
and 68% liquids.  The effluent solids are made up of 98.23%
coal, 0.34% FeSo and 1.43% elemental sulfur.  The liquid
               £
is 2.6% ferrous sulfate, 14.2% ferric sulfate, 0.9% sul-
furic acid and 82.2% water.  The reactor effluent is
cooled to 102°C.

-------
4.1.3.9   Compacting - Dried coal containing 0.33%
less than 5% of the pyritic sulfur in the feed coal, is fed
to disk-type pelletizers.  Lignin sulfonate, 50% solution,
has been tentatively selected as the binder for palletizing.
One and one half pounds of binder, dry basis, is required
per hundred pounds of coal.  Lignin sulfonate has a sulfur
content of approximately five percent, which adds a negli-
gible amount of sulfur to the finished coal.

Another binder recommended by the pelletizer manufacturer is
coal tar pitch.  Seven pounds of coal tar pitch are required
per hundred pounds of coal.  Dry coal tar pitch requires
costly grinding and blending equipment.  Coal tar pitch
emulsion can be used, but a 25% by weight emulsion is
required which would add moisture to the finished coal.

Coal tar pitch binder, added either dry or as an emulsion,
would add an appreciable amount of sulfur to the finished
coal.

The use of styrene-butadiene latex as a binder is discussed
in Section 4.4.
4.1.3.10  Pecantation - Filtrate from filter #2, filtrate
from filter #3, and condensate from drying go to decanters
#1, #2, and #3 respectively.  The organic layers from all
decanters go to the distillation step and are composed of
2.34% sulfur- and 97.66% naphtha.  All of the aqueous layer
from decanter #1 is returned to mixing and has a composition
of 2.7% ferrous sulfate, 14.2% ferric sulfate, 0.9% sulfuric
acid and 82.2% water.  A portion amounting to 16.5% of the
aqueous layer of decanter #2 is returned to mixing and 83.5%
                            -44-

-------
is forwarded to water washing.  The composition of this
aqueous layer is 0.31% ferrous sulfate, 1.62% ferric sul-
fate, 0.38% sulfuric acid and 97.69% water.  The aqueous
layer from decanter #3 is 100% water and goes to the re-
covered water surge tank.  See Figure 10.

4.1.3.11  Iron Sulfates Removal - A stream comprising 31% of
the slurry from mixing is fed to filter #4, a rotary drum
vacuum filter.  The filter cake is discharged into an agi-
tated reslurry tank and returned to the reaction system.
The filtrate is evaporated, cooled and forwarded to filter
#5.  The filter cake from filter #5 is rich in ferrous sul-
fate, and has a composition of 64.96% ferrous sulfate, 6.42%
ferric sulfate, 4.48% sulfuric acid and 24.14% water.  Ten
percent of the filtrate from filter #5 is returned to the
reslurry tank; 90% is evaporated to essential dryness and
is rich in ferric sulfate.  Its composition is 9.91% ferrous
sulfate, 52.97% ferric sulfate, 15.75% sulfuric acid and
21.37% water.  This process design permits varying the
ferrous/ferric sulfate ratio and the quantity of iron
sulfates removed to keep the whole system in the proper
balance.

By-product steam from the evaporator is used to maintain
proper temperature in the mixing vessel and in the reslurry
tank.  The surplus steam is condensed.  Part of the conden-
sate is used to replenish the liquid in the reslurry tank
and the remainder goes to the recovered water surge tank
for wash water for filter #3.  See Figure 11.

#1, #2, and #3 are forwarded to distillation.  Approxi-
mately 50% is filtered in a polishing filter, filter #6, to
remove coal fines which may have passed through filter #2.
The composition of the still feed is 2.34% sulfur and 97.66%
naphtha.  The still feed is preheated to 119°C in the feed/
overhead exchanger.  Heat to the reboiler is supplied by
         2
8.8 kg/cm  (125 psig) steam from the steam plant.  The
condensed naphtha is cooled to 71°Cf the proper temperature
for extraction, combined with the remaining 50% of the
organics which bypass distillation and returned to extraction.
Molten sulfur collects in the steam jacketed bottom portion
of the distillation column to ensure naphtha-free sulfur
product.  See Figure 12.

4.2  REACTOR SYSTEM STUDIES


4.2.1     React ion-Regeneration Kinetic s
The reactions, equations and data used in evaluating the
various reactor designs have been discussed in Section
3.2.1.  These are summarized below and a conversion is
made so that weight ratio can be used rather than weight
percent in the leaching rate expression.

Net overall leaching reaction:

FeS2+4.6 Fe2 (S04)3+4.8H20 — >- 10.2FeS04+4. 8H2S04+0. 8S     (3)

  AH = -55.56 kcal/gm mole  (-100 M Btu/lb mole) FeS2 reacted

Leaching rate :
     dWp/dt  =  - KTWp2Y2                                  (6)
Using the relationships
     Wp = 100 Wr/(l + Wr)  and  dWp = 100 dWr/(l + Wr)2
the leaching rate expression can be changed to
     dWr/dt  =  - KLWr2Y2                                  (9)
where  Wr = weight ratio of iron pyrites to pyrite-free coal

KL = 200,000 exp(-3524.67/T), hr   for -149 micron

       AH = -74.45 kcal/gm mole  (-134 M Btu/lb mole) 02
           reacted

Regeneration rate:
     -dP/dt  =  KRPF2                                      (8)

where KR= 0.402 x 108exp(-6646.5/T), liter/(gm mole)(atm)(hr)
                                                  + 2
      F = concentration of ferrous ion, gm mole Fe  /liter
      P = oxygen partial pressure, atmospheres
      T = absolute temperature,  °K
  or  K = 6.439 x 108exp(-6646.5/T), cu-ft/(lb mole)(atm)(hr)
                    + 2
      F = Ib mole Fe  /cu ft;    P = atmospheres;    T =  °K
The above relationships were utilized in developing a pro-
gram which calculates the output concentrations from the
mixing tank and from the reactor for various combinations
of temperature, pressure, residence time, reactor volume,
input concentrations and percentage pyrites conversion.
The program is included in Section 10.4.1.
4.2.2     Effects of Other Variables
In addition to the variables that are involved  in  the
listed computer program, several other conditions  were
imposed on the calculations and the evaluation  and selec-
tion of reactors.  These were as follows:

          The selection of the materials of construction
          determined the range of operating conditions  for
          the reactors.  Stainless steel #304 will corrode
                       -51-

          in ferric sulfate and sulfuric acid solutions
          above 70°C, and neoprene rubber linings are rated
          as satisfactory only to 102°C.  Therefore, for
          contact with reaction materials above 102°C
          titanium metal or an acid brick lining with a
          neoprene membrane between the brick and the tank
          was chosen.
          The total concentration of iron ions in the
          solution was limited to 5 wt%.
          A liquid/solids ratio of 2 grams solution per gram
          of solids was established as the minimum required
          to adequately slurry and handle the coal in the
          reactor system.
4.2.3     Reactor Configurations Studied
Four types of reactor systems were evaluated by digital
simulation using the stoichiometry and rate equations of
expressions  (3) through  (9).  These types were as follows:
(A) batch reactor,  (B) continuous reactors with an external
unit for the regeneration of ferrous sulfate,  (C) continuous
reactors in series,  (D) continuous reactors in parallel.  A
summary of the results of these simulations at selected
conditions is given in Tables 5-8.  Examples of the program
output are included in Section 10.4.2 following the program
listing.  A discussion of each case is given below.
4.2.3.1   Batch Reactors - The batch reactor system is
efficient from the viewpoint of reaction kinetics, but the
time required to fill and empty the reactor for each batch
reduces the overall efficiency.  An extensive piping and
                      -52-

-------
valving arrangement is required which adds to the cost and
increases the complexity of operation.  An example of the
batch reactor system calculations is given in Table 5.

The feed materials are mixed in an agitated 95 cubic meter
(25,000 gallon) vessel to provide a 15 minute residence
time.  Pressure and temperature in the mixing tank are
atmospheric and 102°C respectively.  Pyrite conversion in
the mixer is 9.7%.  The mixer effluent is heated to 125°C
and charged to the 380 cubic meter  (100,000 gallon) batch
                                          2
reactor.  The oxygen pressure is 5.6 kg/cm  (80 psia).  At
the end of the one hour fill cycle the computed temperature
is 141°C and an additional 38% of the original pyrites
have been converted.  Eight hours after the reactor has
been filled the temperature is 150.4°C and the final  pyrite
conversion is 94.6%.  An alternate way to operate the batch
system would be to feed the mixer effluent directly to the
reactors at 102°C.  The resultant lower temperature would
yield a lower pyrite conversion as shown in Section 10.4.2
in the printout for Batch Reactors, Alternative Run No. 1.
4.2.3.2   Continuous Reactors with External Regeneration -
Initial calculations showed that two large thickeners used
as reactors in series could react 95% of the iron pyrites
if the clear overflow liquor was regenerated with oxygen
in an external plug flow reactor.  A portion of  the  regen-
erated solution would be mixed with the feed streams to
raise the ferric to total iron mole ratio in the thickener-
reactors.  A solution containing 10% by weight of iron was
desirable to minimize the amount of liquid handled in the
                        -53-

-------
thickeners and thus keep them at a  reasonable  size.   How-
ever, serious doubts were raised about the effectiveness
of the thickeners to settle the coal particles using  a
concentrated iron solution.  An example of the calculations
for this system is given in Table 6.

The two thickeners are approximated by two 18,900 cubic
meter  (5 million gallon) perfectly  mixed tanks in series.
The underflow is assumed to be 35 wt% solids.  The clear
                                                          2
overflow streams are regenerated with oxygen at 14.1  kg/cm
(200 psia) and 130°Cf as shown by the regeneration tank
column in Table 6.  Several calculation trials are re-
quired to close a material balance  on the system.  A  more
accurate model of the thickener-reactor would presumably
show better pyrite conversions than those calculated.
Additional data in the form of batch settling tests could
be used to model vertical concentration gradients in  the
thickeners.  These tests should cover a range of liquid
to solid weight ratios from 12:1 to 4:1.
4.2.3.3   Continuous Reactors in Series - A series of con-
tinuous reactors was simulated using a height to diameter
                                                         2
ratio of 3.5, a 150°C operating temperature and 5.6 kg/cm
(80 psia) head pressure.  Each reactor was assumed to be
four well mixed sections in series.  This might be the case
if there were no external recirculation and if baffles or
slow moving agitator arms were used to prevent a maldistri-
bution of flow through the reactor.  A 190 cubic meter
(50,000 gallon) mixing vessel, followed by eight 380 cubic
                      -54-

-------
meter  (100,000 gallon) reactors in series, yielded a 94.4%
conversion of the pyritic sulfur.  Oxygen was fed only to
the first three reactors in the ratios 12:5:2 to maintain
the ferric to total iron ratio at a maximum.  Under these
conditions gas flow would induce intense mixing in the first
reactor, making it one or two well mixed sections rather
than four.  In addition, gas holdup would take up 10-15% of
the reactor volume, so at least one additional reactor would
be required to achieve 95% conversion.  Sample calculation
results for this system are given in Table 7.
4.2.3.4   Continuous Reactors in Parallel - A simpler system
using a 190 cubic meter  (50,000 gallon) mixing tank and ten
380 cubic meter  (100,000 gallon) reactors in parallel was
simulated using a height to diameter ratio of 7.0, a 130°C
                                 2
inlet temperature and a 5.6 kg/cm   (80 psia) head pressure.
Results showed that 95% of the pyritic sulfur was removed.
This system would be cheaper to construct and simpler to
operate as each reactor could be operated independently of
the others.  Each reactor would be a 4.1 meter  (13'-6") di-
ameter by 29.3 meter (96 foot) high tower with both the
coal slurry and the oxygen being fed at the bottom.  Assum-
ing each reactor to be ten well mixed sections 78% of the
oxygen is consumed in the first 6.1 meters  (20 feet) of the
tower.  The heat generated by reaction increases the temper-
ature from 130°C to 149°C at this point.  Heat released
during further reaction is about equal to the average heat
loss from the tower of 259,560 kcal/hr  (1,030,000 Btu/hr)
and the slurry leaves the tower at 147°C.  In order to re-
duce backmixing in the bottom of the tower, some of the
oxygen could be added to the tower at a point ten feet
above the bottom.  Baffles or perforated plates could be
                       -55-

-------
used to maintain good  flow distribution of the  slurry.  A
possible improvement in iron pyrite leaching efficiency
over that calculated should result from the heavier pyrite
laden particles having a longer residence time  in the re-
action tower than coal particles containing low amounts of
pyrite.  On the other hand, several assumptions made in the
parallel reactor calculations would have to be  checked to
verify the results.  The most notable of these  is the extrap-
olation of the regeneration rate equation from  130°C to
150°C.  Oxygen mass transfer rates could limit  the regen-
eration rate to less than that calculated.  The formation
of insoluble compounds at elevated temperatures, as touched
upon in the TRW report   , should also be checked.  Results
from a sample calculation for this system are given in
Table 8.

It should be noted that the calculation for the 380 cubic
meter (100,000 gallon) reactor is for only one  of ten par-
allel reactors, so all flow rates must be multiplied by
ten to get the total flows for the system.
4.2.4     Reactor Selection
The parallel reactor system described above  is used as the
basis of conceptual design for a plant to process 110.33
tons  (121.65 short tons) per hour of dry coal containing
6.7 wt% iron pyrites.  Four identical trains are used as a
basis for the conceptual design which has a  product output
of 9070 metric tons  (10,000 short tons) per  day after fuel
coal and losses are subtracted.  Computer calculations for
the selected design are shown in Table 8, section two.  The
results of these calculations were used as an input for the
plant material balance.  The mixing tank volume was set at
                       -56-

-------
316 cubic meters  (83,525 gallons) so that the ratio of
ferric to ferrous iron ions in the tank effluent was exactly
in the rejection ratio required to maintain the ferric to
total iron ratio in the feed solution at 0.8.  A portion
of the solution is removed and is indicated as sulfate
waste.  Water and sulfuric acid are added to maintain the
system balance.  The resulting slurry is fed to the system
of ten parallel reactors.  The amounts of ferric sulfate,
ferrous sulfate and sulfuric acid leaving the reactor
system are exactly the amounts needed in the mixing tank
feed.  Pyrite conversion of 95% is achieved.

Conventional engineering units were used in the computer
program and in the output tables.  The initial studies were
for an hourly rate of 100 tons of coal containing  6% py-
rites, dry basis, Tables 5-8.

4.3  MATERIALS OF CONSTRUCTION

The materials used for construction and linings are listed
in general terms on the Index Flowsheet, Section 4.5, Figure
13, and in detail in the equipment specifications, Section
10.2.1.  The rationale used in the selection of materials
for good chemical resistance is given in this section.
4.3.1     Leaching and Sulfate Concentration
The dominant materials prescribed for the streams contain-
ing sulfates in the process are brick lined steel, neoprene
lined steel and titanium.  Within its temperature limitation
and subject to the absence of naphtha, neoprene is ideally
suited for handling the coal slurry because it combines good
resistance to acidic ferric sulfate solutions with outstand-
ing resistance to abrasion.  The acid brick lining suggested
for the reactors also possesses these virtues to a high
degree.  Although a properly installed brick lining is an
effective corrosion barrier, in this instance it is only
necessary that it provide thermal protection to the chemi-
cally resistant neoprene membrane.  This protection in depth
should assure long life with minimal maintenance for these
critical vessels.  Also, since the vessel must have a rather
heavy metal wall because of its size and the pressure,
brick lined steel has a favorable cost:  i.e., less than
one-half the cost of any physically acceptable stainless
steel vessel, either solid or clad.  The larger of the
rubber lined vessels should also be somewhat cheaper than
their counterparts in #304 stainless steel.
                      -63-

Both the austenitic stainless steels and titanium should
show low corrosion rates in the strongly oxidizing, acidic
sulfate phases and streams.  Wrought austenitic stainless
steels have been avoided for these streams because the
aqueous phase will undoubtedly contain enough chloride to
assure their premature failure by stress corrosion cracking.
This same judgment does not apply to the cast #316 stainless
steel components of pumps and valves, since the castings
rarely fail due to chloride cracking, presumably because
of their ferrite content.

The estimated maximum chloride levels at which there is a
reasonable chance for an economic life with wrought austen-
itic stainless steels in the oxidizing sulfate streams are:
     1.  10 ppm at 150°C
     2.  20 ppm at 100°C
     3.  50 ppm at  70°C
Factual support for these estimates can be found in the
excellent review on chloride cracking of stainless steels
by Latanision and Staehle, pp. 214-307, "Fundamental Aspects
of Stress Corrosion Cracking", National Association of
Corrosion Engineers, Houston, 1969   , and the paper on
chloride cracking in sulfate solutions by English and
Griess, Corrosion 20, 138t-144t  (1964)
Some savings in capital could be made by qualifying a mixed
ferritic-austenitic or an ultra-low nitrogen ferritic stain-
less steel for the heat exchanger tubes that are recommended
to be titanium.  Complete substitution would appear to save
a maximum of about $50,000 on the project.  This seems
                           -64-

-------
hardly worth, the test effort and the added risk associated
with the change when viewed against the scope of the overall
project.
4.3.2     Sulfur Extraction and Coal Washing
Some preliminary analyses    indicate that the leach step
results in dissolved chloride levels in ferric sulfate solu-
tion of 50 ppm on a once through basis, which by itself
neither increases nor allays the concern about cracking.
These analyses do appear to be contrary to the statements
in "Chemistry of Coal Utilization", Vol. 1, pp. 586 to
   / o \
588   , that 23 to 75% of the chloride content of English
coals containing 3550 ppm chloride or less is removed by
simple water washing.  Extraction of only 10% of the chlo-
ride in Lower Kittanning coal would result in about 250 ppm
chloride in the aqueous sulfate phase.  Such a level of
chloride would be clearly excessive for the #304 stainless
steel recommended for the naphtha extractor.  This point
will need to be adequately documented with laboratory and
pilot plant data.

If the wash water is reasonably low in chloride, the water
wash tank should be safe from chloride cracking.  However,
if use is made of an alternative plan to water wash prior
to the naphtha extractor, the water wash tank can be made
of rubber lined steel and the naphtha extractor can then
be made of #304 stainless steel with good confidence that
both of these vessels will have a long life.

Ceilcote 64 polyester is suggested as a lining for various
vessels handling the naphtha and sulfate solutions.  This
lining is generically a polyester, but it is known that
                     -65-

-------
other polyester linings, which may be superior to Ceilcote
64 for other services, are inferior to Ceilcote 64 in naph-
tha service.  Any alternative to Ceilcote 64 for these ves-
sels should be qualified by testing.  Although a Ceilcote
64 lining will be substantially cheaper than a rubber lining,
it is not recommended for any of the vessels handling coal
slurry because of its relatively poor resistance to abrasion.

The portion of the system for removing sulfur from the
naphtha could benefit from testing or from examination rel-
ative to closely related processes.  Steel has good resis-
tance to dry sulfur but is generally susceptible to severe
corrosion by sulfur in the presence of water and by hydrogen
sulfide in the presence of water.  Accordingly much of this
system has been upgraded to #304 stainless steel.  It is
distinctly possible that carbon steel would be adequate
for some of this equipment.

It is difficult to visualize an alternative sound materials
plan that will substantially reduce the capital require-
ments of the process as now defined.

4.4  LABORATORY STUDIES

The principal objectives of this contract did not initially
include the obtaining of laboratory data; however, the list-
ing of research and development needs was encouraged, and
limited literature analysis and bench work were authorized.
Accordingly, a number of subjects that needed further delin-
eation in the preparation of the process design or in the
consideration of alternatives were listed in the Contractor's
reports to the EPA during the course of the project.  Some
bench work and analysis of the chemistry involved were
undertaken to undergird process design decisions.
4.4.1     Additional Data Needs by Sectors
Listed below are regions in which additional data need
to be obtained as this project progresses.  The sectors
into which the process is divided are defined in the Block
Flowsheet, Figure 1, in Section 4.1.2.  Specific recommen-
dations have been listed in Chapter 2.0.

Coal Handling, Sector OOP — Coal Receiving, Storage, Han-
dling, Sampling and Analysis
               Sectors 900-1000 — Coal Drying, Compacting
and Shipping
     Little new data need to be generated.  Latest rapid
     analytical techniques should be identified for use in
     continuous chemical process control, and minimum dry-
     ing and compaction requirements should be determined
     from utility and coal industry sources.
                     -67-

Leaching and Regeneration/ Sectors 100-400 — Mixing, Leach-
ing, Regeneration and Filtration.
     The chemical reaction portions of this region have
                                          (2 3)
     received much attention at TRW, Inc.  '  , since the
     publication of EPA-R2-73-173a and 173b ^ .  Additional
     suggestions are made in Section 4.2 and Chapter 7.0.
     Techniques from the minerals processing industries
     should be incorporated where economies of bulk solids
     processing can be shown.

Grinding and Screen Analysis of Coal—Samples of ground
coal were obtained from the Company's powerhouses in Midland
and reground to -14 mesh in a laboratory blender.  The
samples were then screened and the -595 micron  (-28 mesh)
portions were used for a number of experiments.  This coal
originated in the southeastern Ohio mines of the Youghiogheny
and Ohio Coal Company  (Y & 0) and the North American Coal
Company  (NA).  Screen analyses are given in Table 9.

Chemical Analysis - Three one gallon coal samples were
obtained from the supplier companies.  These were processed
and analyzed by Commercial Testing and Engineering Co.  (CTE),
Cleveland, Ohio, and used as standards in subsequent work.
The analyses are reported in Table 10.  The different
proximate analyses included represent several standard
commercial reporting procedures used as receiving analyses
along with data for the fusion temperature of the ash.,
which is not reproduced here because it is not pertinent
to this investigation.

Methods of chemical analysis of coal were briefly investi-
gated so that laboratory experiments could be done quickly
and economically if the need developed.  The following
statement by Dr. G. C. Sinke of the Chemical Engineering
Laboratory outlines the method which was chosen:
     "A paper by S. S. Pollack, Fuel 5_0_, 453-4  (1971)
     demonstrated that pyrite when mixed with charcoal
     could be detected down to about 0.2% by weight by
                                                      (9)
                       -70-

-------
     x-ray diffraction technique.  We have determined the
     pyrite in two samples of coal as 3.3% and 6.1%,
     respectively, by standard wet analysis methods.
     Analytical Laboratories personnel examined these
     two samples by x-ray diffraction and found that, by
     plotting peak height versus % FeS2/ one could draw
     a straight line through the origin that fitted these
     two points within 0.2%.  An x-ray diffraction peak
     can be obtained in about 15 minutes.  This rapid
     method can replace the tedious ASTM wet analysis
     procedure with little or no loss in accuracy, and
     it should be exceedingly useful in monitoring pyrite
     removal processes."

Coal Wetting and Settling - One ml of -1190 micron  (-14 mesh)
reground, W. Powerhouse pulverized coal was added to the
surface of 50 ml of liquid in a 2 oz. bottle.  After allow-
ing five minutes for the coal to be wetted, the bottle was
shaken vigorously for one minute and then set on the bench
for settling and observation.  This was repeated for several
liquids with the following results:

                      -71-

-------
The bottles were shaken one to three times per day and
observed for two days.  The coal dispersal remained as
described.  After one month, with shaking one to three
times per week, the appearance was as follows:

     water                 unchanged
     water, toluene        coal dispersed in each layer
     water, hexane         solvent had evaporated
     water, methylene      unchanged
              chloride

The coal was preferentially wetted by the solvent initially,
and then it gradually became distributed in the water and
solvent, in the case of the lighter toluene and hexane.
These observations suggested that solvent-water separation
by decantation should be performed after removal of the
coal by filtration.

Liquid;coal Ratio - In a small test in a 2 oz. bottle it
was found that the following mixtures were stirrable but
that the coal did not stay in suspension when stirring
was stopped.

     Liquid:solids wt. ratio   1.30          1.50

The solvent clung tenaciously to the coal, and solvent-wet
coal stuck to the stirring rod more than did water-wet
coal.

This test indicated that a very low liquid to solids ratio
should be acceptable in the stirred tanks, that solids
                      -72-

-------
accumulation might be experienced in some of the mechanical
operations involving solvent-wet coal, and that complete
removal of solvent from coal filter cake will be very
difficult.  These factors should be investigated and data
obtained to assure an operable design.

Solvent Extraction "of Elemental Sulfur - The solubility of
sulfur in hot chlorinated solvents is so great that these
and possibly other solvents ought to be looked at in the
laboratory in addition to toluene and naphtha.  Proprietary
data show that for elemental sulfur such as contained in
volcanic origin surface ores, the solubility of sulfur
exceeds 40% by weight for a number of chlorinated solvents
near the boiling point of the solvent and approaches in-
finity if the boiling point of the solvent is above the
melting point of sulfur  (113° to 120°C).  Research personnel
of the Western Division, Dow Chemical, U.S.A. have artifi-
cially deposited elemental sulfur on 300 mesh top size coal
and stripped if off successfully with hot trichloropropane

Good sulfur solubilities are also reported for ammonia,
aniline, benzene, carbon disulfide, ethylene dibromide,
sodium sulfide solution, phenol, and pyridine.  The extent
to which these solvents remain on or attack coal and their
ability to remove sulfur should be explored.
4.4.2.2   Use of Chemical Agents with Coal - Samples of
the coal and the iron sulfates standard solution described
in Section 4.4.2.1 were sent to the Company's Designed
Products Department in the following amounts:

     E. Powerhouse Coal, -14 +100 mesh
        (1320 gm of -14 mesh, plus 400 gm
        of reground -14 mesh)
     Iron Sulfates Standard Solution A

Available pertinent literature was reviewed and a series
of laboratory tests was performed at room temperature.  A sum-
mary of the results is given below followed by discussion
                        -74-

Summary
a.   Coal/Water System.  Hydroclones should be evaluated
for their utility in thickening the solids in the coal/
water system, both with and without flocculants.
Anionic polymer flocculants are most effective and may in-
crease settling and filtration rates by a factor of up to
four for polymer dosages in the range of 5 to 25 gm per
metric ton  (0.01 - 0.05 Ib/short ton) of solids.

DOWFAX®* 2A1 surfactant will significantly speed up the
wetting of coal with water.  The chemical cost should be
balanced against the capital and power costs for a high
speed mixer.

b.   Coal/Water/Toluene.  The introduction of solvents into
a solid/aqueous system sometimes causes unusual results re-
lated to wetting.  The addition of DOWFAX 2A1 may help in
getting more of the coal fines out of the toluene layer and
into the water layer in a mixed system.

c.   Coal/Iron Sulfates Solution System.  Nonionic or
slightly ionic flocculation polymers plus dilution water
of about 25% may increase settling and filtration rates by
as much as 30 times at polymer dosages in the range of 62
to 125 gm per metric ton  (1/8 -1/4 Ib/short ton) of solids.
Discussion
a.   Coal/Water System.  In systems where anionic  floccul-ants
are effective, often one polymer will give faster  filter
rates and another faster settling rates.  For the  coal
samples used in this series SEPARAN®* AP 273 flocculant gave

                     -75-

-------
the best  settling  rate with  the  addition  of  25  gm per  metric
ton  (0.05  Ib/short ton)  of solids,  i.e. 25 ppm.   The floes
that formed were quite stable.   SEPARAN AP 30 gave the best
filter rates, and  these  are  shown below.  If, after settling,
it is found that pumping breaks  up  the floes then another
addition  of about  1/5th  as much  polymer may  be  made to
reflocculate the settled solids  before filtering.

The following filter data were obtained for  a slurry
containing 1 weight of coal  to 2 weights  of  water:

The Canadian Department of Energy, Mines and  Resources has
reported good results in improving hydroclone efficiency
using coal/water slurries which were  flocculated with poly-
mers such as the SEPARAN polymers used in this work.  This
was in a paper by J. Visman, and H. A. Hamza, Application
of Flocculants in Hydroclone Separation, The  Canadian Min-
ing and Metallurgical  (CIM) Bulletin, Feb 1973, pp  78-85 (11)
                      -76-

-------
b.   Coal/Water/Toluene System.  A very small amount of
DOWFAX 2A1 surfactant added to the water speeded up wet-
ting of the coal and appeared to cause more of the coal to
transfer to the water layer.  However, the surfactant also
made the water and toluene layers more difficult to separ-
ate.  This is a complex system and needs to be evaluated
in further laboratory tests.

c.   Coal/Iron Sulfate Solution System.  This system gave
results similar to other acid leach systems encountered by
Dow personnel, e.g. uranium acid leach processing.  The
work should be repeated for the actual coal being considered
and at the expected process temperatures; however, the results
reported here may be sufficient for early laboratory stage
planning.

In settling tests, for a starting 25% slurry, i.e. 1 weight
of as-received coal to 4 weights of Solution A, there was no
noticeable settling of the coal in 20 minutes.  Addition of
up to 25% additional volume of water did not improve set-
tling.  The addition of rather large amounts of undiluted
polymer, 250 gm/metric ton  (0.5 Ib/short ton), caused slow
settling to occur, 0.05 cm/min.  However, when the polymer
was added as a dilute water solution, such that 25% additional
volume of water contained 60 to 125 gm polymer/metric ton of
solids in the slurry to be settled, the settling rate in-
creased significantly to 1.3 - 1.5 cm/min.  SEPARAN NP 10
was used as the polymer.

As in the case of settling, the use of polymer and dilution
together gave filtration results much improved over those
of the 25% coal starting slurry.  In the polymer treated
cases the slurry was diluted with about 60 ml of water per
                      -77-

-------
100 ml of slurry, and the slurry was allowed to settle to
a settled solids volume of 50% of the total volume.  Then
the filter tests were performed either without further dilu-
tion or after the addition of 1 volume of additional water
per 4 volumes of settled slurry.  The filter test results
are given below.

The above data are indicative of the results that can be
attained with polymers.  Modifications to the base concep-
tual design case could be made if an economic advantage
were indicated for process changes based on more extensive
bench or pilot plant results.  Some typical Research and
Development projections of such applications are discussed
in Chapter 6.0.

4.4.2.3   Separation and Disposal of Excess Iron Sulfates -
The stoichiometry of the reaction of ferric sulfate with
pyrite is given in Section 3.2.1.  To accomplish depyriti-
zation it is necessary that the dissolved components of
FeS^ ke rejected from the system in the gm mole S:Fe ratio
of 2/1.  It is believed that for each gm mole of FeS2 there
is 0.8 gm mole of elemental sulfur formed, thus leaving 1.2
moles of S to be removed with each mole of Fe.  In order to
achieve a S:Fe ratio of 1.2/1.0, three moles of Fe(II), as
FeSO., need to be discarded for each mole of Fe(III), as
Fe2(S04)3, removed as shown below:

Iron hydroxides that precipitate and remain with the
depyritized coal and sulfuric acid that is formed in the
leach reaction and discarded with the iron sulfates waste
will affect the ratio of Fe(II) and Fe(III) sulfates that
need to be removed.

In addition, care must be taken that the disposal not rob
the system of sulfuric acid needed in the regeneration
reaction.

It was found by a short laboratory boiling experiment that
the vapors emitted from the waste acid iron sulfate solution
were quite acidic, and that there was no formation of large
crystals through evaporation and cooling.  The boiling was
continued until a boiling point of 130°C was reached.  The
resulting wet mass of solids could not be filtered through
                      -79-

-------
filter paper on a Buechner funnel using aspirator  induced
suction and did not solidify at room temperature.

A more careful series of experiments was devised and
performed.  Composite data are shown in Table  11.  A new
stock solution, Solution B, was made up to more nearly
represent the solution leaving the mixer as this solution
was characterized at that point in time in the development
of the material balance calculations.  Ultimately  these
experimental data were substituted in the material balance
calculations to provide a more accurate characterization.

In order to approach the 3 to 1 mole ratio of  Fe(II) to
Fe(III) most readily, the inlet stream to the  iron sulfates
removal sector was taken as the acidic filtrate resulting'
from filtering a side stream of coal slurry leaving the mixer.

It was learned that at about 112°-118°C the liquor was con-
centrated to the point that about 50% of the material was
solid crystals in suspension.  These crystals were filtered
off, washed with saturated ferrous sulfate solution and the
resulting mixed iron sulfates cake was about 50% FeSO, with
appreciable Fe^CSO.)., and H^SO. as shown in Table  11.  The
remaining filtrate or mother liquor could be recycled to the
process or evaporated further and removed from the system
after passing over a drum dryer or flaker.

Similar data are plotted on a ternary diagram  in Chapter
7.0.  The data were used in the design of Sector 1100 and
in the Reaction Program summarized in Table 8 with minor
changes.  The experiment should be repeated as the con-
ceptual design undergoes further change and refinement.
                      -80-

-------
Analysis of the sulfuric acid in these cakes was made
difficult by interference of the iron salts in the colori-
metric end point.  Finally, it was discovered that acetone
could be used to extract the acid and free water away from
the solids and that the resulting extract could be readily
titrated.  This type of acetone extraction could be utilized
to recover sulfuric acid as needed for the process and to
provide a less corrosive waste sulfates refuse.

The conceptual design includes facilities and provision to
haul the excess ferrous and ferric sulfate solids to some
offsite disposal area.  The ultimate disposal of the acid
iron sulfates cannot be decided on independently of the
economics and opportunities existing in the area of the
actual plant sites.  However the following ideas are
listed for consideration:

  a.  Precipitate iron hydroxide and calcium sulfate mate-
  rials with further disposal in the manner of some of the
  acid mine wastes in Pennsylvania and West Virginia.  In
  this regard it has been found that PURIFLOC®* A23 or
  SEPARAN A273 flocculants are effective in promoting
  settling of iron hydroxide in dilute solutions up to 60°C.
  These methods could be useful if it was decided that
  residual traces of iron sulfate should be precipitated
  out of some of the wash streams.

  b.  Include an acetone extraction step in the process
  to recover the acid, or determine what other solvents
  would be suitable.

        The condensate had 0.2 - 0.3% H2S04 from the first evaporator and 0.3 -0.4%

-------
c.  Separate the ferrous sulfate, neutralize any acid and
reduce ferric ions  (for example, with scrap iron), make a
concentrated water solution to be used by itself or in
combination with magnetite or clay as a heavy media for
gravity separation of feed coal preceding the process.
Corrosion studies on completely neutralized ferrous sul-
fate separated from a pilot plant process would show the
suitability of using such a heavy medium in commercial
carbon steel equipment.

d.  Utilize the acid ferric sulfate as a solution to
pretreat and partially depyritize either the coal feed
to the process or high gravity coal/ash mixtures that
might be ultimately used as a process fuel source.

e.  Utilize existing technology to react iron sulfates
from chemical desulfurization to yield S0« and iron
oxide.  Use other technology to produce H?S and iron
oxides from pyrite concentrates derived from coal
washing.  Combine the S02 and H-S in a Glaus-type
process to produce marketable sulfur.  Sell the iron
oxide as is or upgrade it for sale.

f.  Table 22 in Chapter 6.0 lists the value and likely
disposition for by-products if there were many chemical
leaching plants in a given region.  Three other possi-
bilities may be mentioned here.

— A small quantity of ferrous sulfate is used in an
   organic chemistry catalyst system wherein ferrous
   sulfate and hydrogen peroxide are combined to form
   Fenton reagent.  This material is able to supply
   hydroxyl radicals which attack certain classes of
                    -83-

-------
organic compounds to effect a transition or, in
some cases, a destruction of the molecules.

A suggestion was made early in the program that elec-
trolytic iron might be a good outlet for iron oxide
or iron sulfates.  This alternative is discussed in
the following statement from Dr. Bruce C. Peters,
formerly in the Electrochemical & Metallurgical
Corporate Research Laboratory, "The possibility of
using an electrolytic scheme to aid in the disposal
of the iron sulfate is considered to be small and would
require research in the area to ascertain the practica-
bility of it.  There are no commercial production routes
to iron using electrolysis.  Several have been tried
using both iron sulfate and iron chloride, but the
problems appeared to be too great.  Approximately
2% of the iron powder produced is prepared electro-
lytically, however, this is an electrorefining rather
than an electrowinning operation.  Both chloride and
sulfates electrolytes are used    '    .

Dr.  Stacy L. Daniels, Environmental Control Systems
Group, Functional Products and Systems Department,
contributed the following statement concerning
environmental and process aspects of ferric compounds:
"The iron sulfate waste stream can be expected to be
contaminated with coal fines, colloidal sulfur,
calcium sulfate, and trace amounts of other compounds
and elements.  A stewardship program would need to
be developed for such excess leachate very much
along the lines of the Company's recent program for
a new grade of ferric chloride resulting from leach-
ing titanium bearing ores.
                 -84-

-------
     "The use of ferric chloride as a leaching agent in-
     stead of ferric sulfate merits continued consider-
     ation so that the best choice can be made regarding
     overall capital cost, side reactions and residuals,
     and disposal problems or opportunities related to
     the nature of the discharged anion.

     "Excess leachate would have to compete in quality and
     price with existing ferric chloride and waste pickle
     liquor supplies.  On an equivalent iron basis the
     price for Fe2(S04)3 would have to be 80% of the
     current price for Fed.,."

     The September 1974 price for sewage grade FeCl., was
     $80.00/T, anhydrous basis, or about $232/T of Fe.  For
     partly hydrated Fe~(SO.)., the price was $39/T  (71%
                                      (2fU
     Fe2(S04)3) or about $197/T of Fev  ', i.e., 85% of the
     equivalent iron price for FeCl3.  The large markets for
     sewage grade ferric ion are in the metropolitan areas
     and supply contracts are heavily dependent on
     transportation costs.
4.4.2.4.  Compacting of Fine Coal - Lignin sulfonate is
used in the base case as the binder for compaction.  Pitch
is another alternative.  Both of these have sulfur contents
themselves and both could be in short supply if a number
of coal plants began using them.

Development personnel of the Dowell Division, Dow Chemical
U.S.A., have been working for over three years on methods
to make the handling and shipment of coal fines practicable.
They have worked with a number of companies on commercial
applications of their developments, and additional work and
new developments are in progress.
                       -85-

-------
Dowell has found that film forming latexes can be utilized
with other additives in an ecologically suitable binder to
agglomerate -841 micron  (-20 mesh) coal fines to minimize
losses from wind and handling.  The  following was compiled
from internal Company reports by K.H. Nimerick and a letter
by C. F. Parks of Dowell(12/13'14).

In a typical pelletizing operation the binder is first mixed
with the coal fines and then this mixture is fed continu-
ously onto a revolving pelletizing disk.  Additional liquid
may be dripped onto the revolving coal charge.  The pellets
are formed and compacted by centrifugal force.  As the
number of pellets increases, they gradually overflow the
volume of the disc and fall into a collection bin.  These
pellets are then cured by drying to  form pellets with
sufficient dry strength for handling.

A wide range of binder agents was tested.  The preferred
system is based on a water slurry containing 4% by weight
of Wyoming bentonite clay.  To this  is added DOWELL®* Ml66
latex binder, a styrene-butadiene latex emulsion in water.
For 0.9 metric tons (1 short ton) of coal fines the slurry
would contain 10.9 kg (24 pounds) of bentonite, 2.6 to 4.0
liters (0.7 to 1.05 gallons) of DOWELL M166 and 272.5 liters
(72 gallons) of water.  The cost of  chemicals would be on the
order of $3.03 per metric ton  ($2.75 per short ton) of coal.

Another approach to the problem of wind erosion is the
spraying of a binder mixture onto the surface of coal in
open rail cars or in stockpiles.  An efficient binder has
been developed and is coded DOWELL M167.  It is a blend of

*Trademark of The Dow Chemical Company.

                      -86-

-------
styrene-butadiene latex, a surfactant, and ethylene glycol.
The surfactant allows rapid wetting and penetration of the
particulate materials.  The ethylene glycol provides freeze-
thaw stability to the M167, and the latex forms a water re-
sistant crust which prevents wind erosion.  The M167 is free
of sulfur, halogens and heavy metals that may be of ecolog-
ical concern.

The DOWELL M167 is applied to the coal surface as a 4 to 10%
aqueous dilution such that 15-22.7 liters  (4 to 6 gallons)
                                    2
of aqueous slurry are used per 9.3 M   (100 square feet).
Finer sized particles require larger volumes and higher
concentrations of binder.  This amount of slurry applied
to the surface produces a 0.6 to 5.1 cm  (0.25 to 2.0 inch)
thick crust that will cure at ambient conditions.  At 90%
humidity, 11.3 liters (3 gallons) of 10% M167 per 9.3 M2
(100 square feet) will cure in two hours; 30.3 liters  (8
jallon!
hours.
                  2
gallons) per 9.3 M   (100 square feet) will cure in 10.5
The amount of chemical agents or M167 used for a 91 metric
ton  (100 short ton) open rail car would be in the order of
4.7 to 9.5 kg  (10 to 20 pounds), or about 0.017%.  For an
assumed $0.072 per kg  ($0.32 per pound) average binder cost
this would amount to $0.055 per metric ton  ($0.05  per short
ton) for the chemical cost.  The added moisture would be
negligible compared to that occurring in coals exposed to
the weather, e.g. from less than 0.3% for a  10% dilution
to 0.75% for. a 4% dilution.  Where the right conditions
could be set up, as in the spraying of open  cars or piles
and supplementary water spraying of intermediate transfer
points, this could be an attractive alternative to
complete pelletizing.  Additional stockpile  stabilization
at the user's plant would cost less than in-transit
stabilization.

4.5  PROCESS DESIGN

The process design description that follows is divided into
sectors.  Reference is given to the appropriate process
flowsheet, the plot plan and/or process train layout draw-
ings, the stream numbers in the mass-energy balance, and
the equipment specifications.  Figure 13 is an index flow-
sheet showing the complete chemical processing.  Figure 14
is a legend sheet showing symbols and abbreviations.  No
attempt has been made to distinguish between U.S. horse-
power and metric horsepower because the 1.4% difference
is less than the limits of error in the specification.
4.5.1   Coal Preparation-Sector OOP;
        (Figure 15, Process Flowsheet #1)
Mine run coal, in 200 mm  (8") maximum lump size, is re-
ceived by rail in 90 metric ton (100 short ton) cars.  At
capacity,  130 cars per day are required.  Provision is made
for bottom dump cars or conventional cars, which utilize
a rotary car dumper #002*.  It is assumed that the cars
will be moved through the car dumper house #001 by the
railroad company.

From hopper #003 under the dumper four  feeders #004A-D
discharge onto collection conveyor  #005, which discharges
to conveyor #006.  All conveyors operate at  2270 metric tons
(2500 short tons) per hour to permit daytime unloading.

Coal is weighed on belt scale #007  and  tramp iron is  re-
moved by magnetic separator #008, each  of which is contained

*Numbers refer to equipment numbers on  the flowsheet  and  in
 the equipment list and equipment specifications in the

in transfer tower  #009.  Distributing conveyor  #010 moves
the coal onto an open storage pile approximately  25 x  145
meters  (82 x 475 feet).  This pile provides 2.6 days of
"live"  storage at  capacity.  Additional  "dead"  storage
may be  provided by transport to and  from an adjacent area.

From the "live" storage pile two rotary  plow feeders #011-A&B
deliver the coal at 485 metric tons  (535 short  tons) per
hour to reclaim conveyor #012, which delivers the coal to
#013 conveyor.  This conveyor feeds  #014 belt scale, #015
magnetic separator, and surge bin #022 in the crusher-
pulverizer house #021.  From surge bin #022 two feeders
#023-A&B feed crushers #024-A&B which feed pulverizers
#025-A&B.

Conveyor #031 conveys the -149 micron, U.S. Sieve Series,
(-100 mesh, Tyler  Standard Screen Scale  Sieve Series) pul-
verized coal to conveyor #032, which delivers the pulver-
ized coal to four hoppers #033-A-D located at process
trains  #1 to #4, respectively.

Provision is made in the capital estimate, and will be made
in the detail design, for dust control and fire protection.

The particle size distribution after pulverizing  is assumed
to be as shown in Table 12.

           (Figure 16, Process Flowsheet #2)
Stream #1, -100 mesh pulverized coal, from hopper #033-A
and weight recording-controlling feeder #034-A feeds eleva-
tor #100-ME-1, which feeds #100-V-1 mixing tank of 320
cubic meters  (85,000 gallons) capacity.

Wetting of the pulverized coal with leach solution is ac-
complished by proper geometry of the vessel and proper
agitator design.  Baffles in the lower portion of the
vessel only allow the upper turbine of the agitator to
create a vortex which induces the fine coal into the leach
solution.  The lower turbine and the baffles in the lower
portion of the vessel ensure good mixing.

Approximately 14% of the FeS2 is leached during the one
hour residence time in the mixing tank -at 102°C  (215.6°F).

Stream #4, a composite of Streams #32, #14, #12, and #2
subsequently described, provides the leach solution.

Vent scrubber #100-V-2 prevents coal fines from being
vented from the mix tank.

Stream #11, steam from Stream #25 subsequently described in
Sector 1100, provides the necessary heat to maintain proper
leaching temperature in #100-V-1.  Stream #3, the vent from
scrubber #100-V-2, goes to a vent scrubbing system subse-
quently described in Sector 1500.

Sulfuric acid, required to compensate for the sulfuric acid
lost with the waste iron sulfates, is fed from #1100-T-2,

subsequently described in Sector 1100.

Each reactor has a 4 meter  (13' - 1-1/2") diameter, mea-
sured inside of the brick lining, and a 27 meter  (88'-6")
straight side, with hemispherical top head and elliptical
bottom head.  The reactor shell is steel, lined with 6.35
mm  (1/4") neoprene and 114.3 mm  (4-1/2") of acid brick.
The acid brick provides thermal insulation to protect the
neoprene lining.

Stream #6, 99.5 volume percent pure oxygen, is fed to two
titanium spargers for distribution into the slurry.

The volume inside of the brick lining is 340 cubic meters
(90,000 gallons) including  75 cubic meters  (20,000 gallons)
for foam disengagement should this be necessary.

The exothermic reaction results in a temperature rise from
102°C  (215.6°F) to 151.6°C  (304.9°F).

Inerts are vented via stream #8 to the vent scrubbing system
subsequently described.

The reactor product, Stream #9, with >95% of the FeS-
converted, goes to cooler #200-E-1, composed of 50 square
meters  (550 square feet) of titanium tube surface, where
it is cooled to 102°C  (215.6°F).
4.5.4     Filtration - Sector 400;
          (Figure 17, Process Flowsheet #3)
The reactor product, at 102°C (215.6°F) from #200-E-1
cooler, Stream #10, is fed to four rotary vacuum drum
filters #400-F-1 A-D where the coal is removed from the
mixed acid sulfate solution.  Each filter has 77 square
meters  (836 square feet) of filter area.'  The filters are
of neoprene lined construction with polypropylene filter
cloth.  When all four filters are in service a filter rate
of 1.0 cubic meters of feed per hour per square meter of
filter area (0.4 gallons per minute per square foot) is
adequate.  When only three filters are in service, as
would be the case when one filter is shut down for mainten-
ance, a 33% increase in throughput for each filter would
be needed.  Each filter is furnished with a vacuum pump,
filtrate receiver, 2 filtrate pumps  (1 spare), level control,
and high and low pan level switches.

Filtrate containing ferrous and ferric sulfates and sul-
furic acid from the four filters, Stream #2, is returned
to the mixing tank #100-V-1 via Stream #4.

The coal filter cakes from the four filters discharge into
conveyor #400-ME-1, Stream #15, where they are carried  into
the extractor #500-V-1 described in the following sector.

4.5.5     Extraction  -  Sector  500;
           (Figure 18, Process  Flowsheet  #4)
Stream #15, coal filter cake from conveyor  #400-ME-1,  is
discharged into #500-V-1, a 150 cubic meter  (40,000  gallon)
extractor of  #304 stainless steel with a 50  horsepower agi-
tator also of  #304  stainless steel.

Naphtha containing  approximately 1.2% sulfur, Stream #37,
is fed to the  extractor.  Stream #37 is  composed of  Streams
#31 and #73 described later in Sector 1400.

Stream #201 is the  vent from the extractor to the vent
scrubbing system described later in Sector 1500.

Stream #27, the coal-naphtha slurry, containing the  sul-
fates carried  over  in the filter cake, Stream #15, is  fed
via pump #600-P-1 to process filtration  described in the
following sector.
4.5.6     Filtration and Decantation - Sector 600;
           (Figure 18, Process Flowsheet #4)
Stream #27, pumped by 25 HP, #316 stainless steel centrif-
ugal pumps #600-P-1 A&B  (one spare), is fed to four rotary
vacuum filters #600-F-1 A-D where the coal is removed from
the naphtha and residual sulfates.  Each filter has 77
square meters  (836 square feet) of  filter area.  The fil-
ters are of #304 stainless steel construction with #304
wire mesh filter media.  When all four filters are in
service the filter rate is 0.92 cubic meters of feed per
hour per square meter of filter area  (0.37 gallons of feed
per minute per square foot).  With  three filters in service

the filter rate is increased one third.  Each filter is
furnished with vacuum pump, filtrate receiver, two filtrate
pumps (one spare), level  control, and high and low pan
level switches.

Filtrate, naphtha and residual sulfates, Stream #30, are
fed to #600-V-1 decanter, 68 cubic meter  (18,000 gallons)
steel vessel with Ceilcote #64 polyester lining.

The aqueous sulfate layer, Stream #32, is pumped by 5 HP,
#316 stainless steel centrifugal pumps #600-P-2 A&B (one
spare) to the mixing tank #100-V-1 via Stream #4 described
in Sector 100.

The organic layer of naphtha containing 2.3 weight percent
sulfur,  Stream #38, flows by gravity to #1400-T-1 still
feed tank described later in Sector 1400.

The coal filter cake from the four filters is discharged
onto conveyor #600-ME-1 as Stream #29, which is discharged
into #700-V-1 water wash tank described in the following
sector.

Wash, water, Stream  #44, composed of  1.9%  sulfates,  1.6%
naphtha, and 96.5%  water,  is  fed to  the mixing  tank.
Stream #44 is produced  from Streams  #43 and  #41  described
in the following sector.

Stream #39, water-coal  slurry,  is pumped  by  pumps  #800-P-1
A&B  (one spare) described  in  the following sector.
4.5,8     Filtration and Decantation  -  Sector  800;
           (Figure 19, Process Flowsheet #5)
Stream #39, water-coal slurry,  is pumped by  25 horsepower,
#316 stainless steel centrifugal pumps  #800-P-1 A&B  (one
spare) to four rotary vacuum drum filters  #800-F-1 A-D where
the coal is removed from the water  in the  feed and washed
with hot water, Stream #47, from pumps  #1100-P-3 A&B de-
scribed in Sector 1100.  Each filter  has 77  square meters
(836 square feet) of filter area.   Filters are of #304
stainless steel with #304 wire  mesh filter media.

When all four filters are operating the filter rate is 0.74
cubic meters of feed per hour per square meter of filter
area  (0.3 gallons of feed per minute  per square foot).  When
only three filters are in service the filter rate is in-
creased one third.  Each filter is  furnished with vacuum
pump, filtrate and wash receivers,  2  filtrate  pumps, 2
wash pumps (one spare each), level  controls  on receivers,
and high, and low pan level switches.

Filtrate composed of 2% sulfates, 13% naphtha, and 85,%
water, Stream #42, is fed to #800-V-1 decanter, 38 cubic
meters (10,000 gallons) steel lined with Ceilcote #64.

The aqueous layer composed of 2.3% sulfates and 97.7% water,
Stream #40, is split into Stream #14, which goes to #100-V-1
mixing tank via Stream #4 described in Sector 100, and Stream
#43.  Stream #41, wash water from the filters, is 93.5% wa-
ter, 5.3% naphtha, and 1.2% sulfates.

Streams #43 and #41 are combined into Stream #44, the wash
water to the extractor #700-V-1, as described in the pre-
vious sector.

The organic layer, Stream #33, composed of 2.34% sulfur and
97.66% naphtha, travels by gravity to still feed tank #1400-
T-l described in  Sector 1400.

The washed coal filter cake from the four filters is dis-
charged onto conveyor  #800-ME-1, Stream #45, which feeds
the coal driers #900-ME-1 A&B, described in the following
sector.
4.5.9     Drying and Decantation -  Sector  900:
           (Figure  20, Process Flowsheet  #6)
Stream #45, washed coal filter cake from conveyor  #800-ME-1
described in the preceding sector,  is  split  and  feeds  two
drying and  solvent recovery systems #900-ME-1 A&B.   The
coal is dried  in a nitrogen atmosphere under positive
pressure to avoid  air in-leakage and resultant fire  hazard.

Condensed water and naphtha from the dryer condensate
receivers, Stream #48, flows to #900-V-1 decanter of 3.8
cubic meters (1000 gallons) volume.  The water layer, Stream
#51, flows by gravity to #1100-T-1 surge tank described in
Sector 1100.  The naphtha layer, Stream #50, flows by grav-
ity to #1400-T-1 still feed tank described in Sector 1400.

The dried coal, Stream #53, from the dryers is fed to con-
veyors #900-ME-2A (from dryer #900-ME-1A) and #900-ME-2B
(from dryer #900-ME-1B) discharging to conveyor #900-ME-3,
which feeds the compactor described in the following
paragraph.
4.5.10    Compacting - Sector 900;
           (Figure 21, Process Flowsheet #7)
Dried coal from conveyor #900-ME-3 is fed to a  7.6 M
(25 foot) diameter rotating disk compactor  #900 ME-4.
Lignin sulfonate binder is unloaded via 5 HP ductile iron
pumps #900-P-2 A&B  (one spare) into a 1136  M   (300,000
gallons) steel tank #900-T-1 and pumped by  1 HP ductile
iron pumps #900-P-1 A&B  (one spare) to #900-ME-4 compactor.
Pellets of 13 to 38 mm  (1/2" to 1-1/2") are formed and
dropped into elevator #900-ME-5, which discharges onto
conveyor #1001 described in the following sector.
4.5.11    Product Coal Handling -  Sector 1000;
           (Figure 22, Process Flowsheet #8)
Dried and compacted coal,  95% pyrite-free with  4%  moisture,
from elevator #900-ME-5 in each of the four  process  trains
is discharged onto conveyor  #1001,  and then  is  loaded into

silos #1006 A-D via conveyors #1002 and #1005.  The rein-
forced concrete silos are 21.3 meters diameter by 36.5
meters high  (70 feet by 120 feet).  Each hopper provides
6800 metric tons  (7500 short tons) storage or 64 hours for
each process train at capacity.

Seven feeders #1007 A-D(l-7) under each hopper feed the
product coal to conveyor #1008 at 1630 metric tons per
hour  (1800 short tons per hour) to the car loading house
#1009.  This rate allows car loading of 9070 metric tons
(10,000 short tons) during the day shift.
4.5.12    Iron Sulfates Removal - Sector 1100;
          (Figure 23, Process Flowsheet #9)
Stream #16 described in Sector 200 is fed to two rotary
vacuum drum filters #1100-F-1 A&B where the coal is re-
moved from the sulfate solution.  Each filter has  57
square meters  (620 square feet) of filter area.  The  fil-
ters are neoprene lined construction with polypropylene
filter cloth.  The filter rate is 1.06 cubic meters per
hour per square meter  (0.43 gallons per minute per square
foot) of filter area.  Each filter is furnished with  a
vacuum pump filtrate receiver, 2 filtrate pumps  (one  spare),
level control, and high and low pan level switches.

Stream #18, coal filter cake, is discharged into #1100-V-2
reslurry tank, 11.4 cubic meters  (3000 gallons) volume,
neoprene lined, with a 2 horsepower, neoprene covered
agitator, #1100-A-1.

Filtrate from the above filters is fed to  #1100-V-1 concen-
trator, 19 cubic meters  (5000 gallons) volume, titanium or
titanium clad.  Reboiler IllOO-E-l has 422 square meters
(4600 square feet) of titanium tube surface heated with 8.8
     2
kg/cm   (125 psig) steam.
Stream #25, vapor from the above concentrator,  splits into
Stream #26, which feeds #1100-ME-1 water heater described
later, and Stream #11, which go.es to #100-V-1 mixer de-
scribed, in Sector 100 and Stream #17, which goes to reslurry
tank #1100-V-2 described above.

Stream #21, concentrated sulfates, travels to #1100-E-2
cooler, 4.5 square meters  (49 square feet) of titanium
tube surface, and is cooled from 143.3°C  (290°F) to 102°C
(215°P) and becomes Stream #121.

Stream #121 feeds #1100-F-2 filter, identical to filter
#1100-F-1 A or B.  The cake from the filter, Stream #122,
is rich in ferrous sulfate and is part of the iron
sulfates waste.

The filtrate from the above filter, Stream #123, is split
into streams #24 and #118.

Stream #24 is fed to #1100-ME-2 evaporator-dryer and evapo-
rated to dryness.  This stream is rich in ferric sulfate and
is the balance of the iron sulfates waste.

It is of the utmost importance to remove the exact amount
of iron and sulfur, which enters the system as FeS2, iron
pyrite in the coal.  It is also of the utmost importance
to remove ferrous and ferric sulfates in the same ratio
as they are formed.

The above iron sulfates removal system permits varying the
two waste streams to ensure removal of the proper amount
of ferrous sulfate and ferric sulfate.

Stream #118 is returned to #1100-V-2 reslurry tank de-

Stream #119, water from pumps #1100-P-3 A&B,is fed to #1100-
V-2 reslurry tank, volume 11.4 cubic meters  (3000 gallons),
neoprene lined, to provide vehicle for returning the coal
filter cake from #1100-F-1 to the reaction system.

Sulfuric acid makeup is required to compensate for the sul-
furic acid lost with the waste iron sulfates.

Sulfuric acid is unloaded into tank #1100-T-2, 114 cubic
meter  (30,000 gallons) steel tank, pumped by pumps #1100-P-4
A&B  (one spare), 1-1/2 horsepower, ductile iron pumps via
stream #56 to the mixer #100-V-1 described in Sector 100.

Stream #23, the coal-sulfates slurry from reslurry tank
#1100-V-2, is pumped by pumps #1100-P-1 A&B  (one spare),
60 horsepower* #316 stainless steel, to stream #7 which
feeds reactors #200-R-1 A-K described in Sector 200.

Stream #52, water vapor from dryer #1100-ME-2 mentioned
above, goes to recovered water surge #1100-T-1, 570 cubic
meters (150,000 gallons), red lead phenolic lined  (Federal
Specification TTP-86, Type 4) steel tank.  Heat exchanger
#1100-E-5 mounted on top of #1100-T-1 condenses water vapor.

Stream #55a or #55b provides fresh process water makeup or
excess water waste removal, respectively, depending on the
moisture content of the raw coal.  With the assumed 10%
moisture in the coal and no losses there will be a small
amount of waste water discharged, e.g., 3.85 TPH per
train discharged  (see Figure 1).

Stream #124, dried ferric sulfate-rich waste from dryer
#1100-ME-2, is combined with Stream #122, the ferrous
sulfate-rich waste, to form Stream #22, the iron sulfates
waste, for disposal.

into Stream #73, described in Sector 500, and Stream #72.

Stream #72 is filtered through Filter #1400-F-1  to remove
coal fines which have passed through the other coal fil-
ters.  Stream #72, which has 2.4% sulfur and is  free of

The preheated still feed from #1400-E-2, Stream #74, is
fed to the middle tray of distillation column #1400-V-1,
2.7 meters diameter by 9 meters overall height  (9 feet by
30 feet).  The column has three ballast trays.  The column
is #304 stainless steel, but 20% - #304 stainless steel
clad is also acceptable.  The bottom 1.5 meters  (5 feet)
is jacketed.  This jacketed section provides heated surge
for complete removal of naphtha from the recovered sulfur.

Recovered naphtha-free sulfur Stream #35, goes to sulfur
surge tank #1400-T-3, 90 cubic meters  (24,000 gallons) and
is pumped by sulfur loading pump #1400-P-4 to tank truck or
tank car loading.  Pump #1400-P-4 is steam jacketed and all
sulfur pipelines are steam jacketed to keep sulfur at a few
degrees centigrade above its melting point.

Heat for distillation is supplied by a steam heated thermo-
siphon reboiler #1400-E-1, 156 square meters  (1700 square
feet), #304 stainless steel tubes.

Stream #75, overhead vapors from #1400-V-1, goes to the
above mentioned heat interchanger.  Stream #76,  the par-
tially condensed vapors, goes to the condenser  #1400-E-3,

#57 for reflux to the top tray of  #1400-V-1, and Stream  #36
to cooler #1400-E-4, 168 square meters  (1832 square feet),
#304 stainless steel tubes and to  recovered naphtha surge
tank #1400-T-2, same size and material  as  #1400-T-1.

Stream #31 from #1400-T-2 is pumped by  pumps #1400-P-3 A&B
(one spare) to Stream #37 described in  Sector 500.

Makeup naphtha is received by tank truck  and loaded into
#1400-T-4, a 19 cubic meter  (5000  gallon)  storage tank,
and pumped by 1400-P-5 pump, 1 horsepower, ductile iron,

cubic meters  (10,000 gallons), steel, with perforated baffle
and weir, through. #1500-E-1, 13.9 square meters  (150 square
feet) steel heat exchanger to I1500-V-1 scrubber tower de-
scribed above.  The pH of the scrubber solution is recorded
and manually controlled by the addition of 50% caustic soda.
This neutralizes any sulfuric acid and hydrogen sulfide,
which may be formed from sulfur in contact with organic
solvents.

Condensed naphtha is decanted and pumped by pumps #1500-P-2
A&B  (one spare) to the still feed tank described in
Sector 1400.

The vent from #1500-V-1 is estimated at 91 kg  (200 pounds)
per hour of nitrogen and inerts, 54 kg (120 pounds) per
hour of naphtha, and 3 kg (7 pounds) per hour of water
vapor, all figures per train.  Inasmuch as emission reg-
ulations prohibit this quantity of hydrocarbons, it will
be necessary to provide an adsorption unit to decrease
the emission of hydrocarbons to less than the allowable
limits.  The estimated quantities are too inaccurate to
warrant specifying the adsorption unit until pilot plant
operations yield meaningful data on quantity and composi-
tion of the feed stream to the adsorption unit.

Stream #81, waste water, is estimated to be approximately
227 kg (500 pounds) per hour, per train, 97%  (by weight)
water, 2% caustic soda, and 1% sodium sulfide and sulfates.
It appears feasible to forward this waste to either #1100-V-1
evaporator or #1100-ME~2 evaporator/dryer.  Disposition
of this should await pilot plant data for finalization.

4.8  PLANT LAYOUT

The layout of the complex is tentative and can be finalized
after selection of the site.  The arrangement of equipment
is also tentative and can be finalized after completion of
final process and equipment design based on pilot plant
operations.  The tentative layout and arrangements are
described in the following paragraphs.
4.8.1     Plot Plan
Figure 26 is a tentative layout of the entire complex.  It
shows the locations of the coal preparation facilities de-
scribed in Section 4.5.1, the four identical process trains
described in Sections 4.5.2 to 4.5.10 and 4.5.12 to 4.5.14,
the product coal handling described in Section 4.5.11, the
utility facilities described in Section 4.8.3, and the
general facilities described in Section 4.8.4.
4.8.2     Equipment Location
The plan location of the equipment in each of the four iden-
tical process trains is shown in Figure 27 for the ground,
second, and third floors, and Figure 28 for the fourth,
fifth, and sixth floors.
4.8.3     Utilities
Figure 29 is a diagrammatic representation of the utility
facilities.  These are listed as follows and described in
Section 10.2.1 of the Appendix.

A 20 hectare  (50 acre) site has been assumed with 13
hectares  (31 acres) cleared, fenced, and developed with
roads, parking area, surfacing, landscaping and railroad
tracks.  One track is provided for incoming coal and empty
outgoing cars, one track for empty incoming product coal
cars and full product coal cars, and the third for unload-
ing raw materials and loading product sulfur and waste
sulfates, all as shown in Figure 26.
4.8.4.2   General Facilities - The major general facilities
are the administration building and the maintenance shop
and stockrooms and stores building.  The location of these
is shown in Figure 26.

The administration building has been assumed to have 2200
square meters  (24,000 square feet) of floor area for office
space for the administrative personnel.

The maintenance shop and stores building has been assumed
to have 5500 square meters  (60,000 square feet) of floor
area for maintenance and stores personnel, shop equipment
and tools, and spare parts and maintenance materials.

5.1.1     Capital Cost Estimate and Related Costs
5.1.1.1   Capital Cost Estimate - The capital costs are
given in Table 13 for complete engineering, purchasing,
and installation of battery limits equipment and off-site
utilities and facilities for the plant whose conceptual
design is developed in Chapter 4.0.  Details for the
sectors are presented in Sections 10.2, Equipment; 10.3,
Instrumentation; and 10.6, Capital Costs.  The estimates
are based on major equipment costs from vendors' quotations
or Company purchase records.  These data are built up on
a unit operations basis for the components of each sector
using judgment, plus conventional and proprietary factors.

5.1.1.2   Capital Related Costs - A large proportion of the
operating costs is related to capital.  The detail is given
below for depreciation, maintenance, insurance and taxes.

Depreciation - The data of Table 13 are regrouped in Table
14 according to depreciation category.  Depreciation is
calculated on a straight line basis, i.e., for 20 year
depreciation l/20th or 5% of the original capital is
taken as an annual cost.

Maintenance - Annual expenditures for maintenance materials
and labor, spare parts, replacement, and revisions are
variable and need careful control.  For purposes of a
cost estimate an overall maintenance cost of 4.0% of the
capital was chosen.

Insurance and Taxes - The annual premiums for fire and loss
insurance are directly related to capital values, as are
local property taxes and some state taxes.  A total of
2.0% for these is realistic.

General and Administrative - A number of cost and capital
items that are important but relatively small in some cases
are grouped in Table 14 as "G&A and working capital."  An
example of the items included in working capital is given
below.  Inventories were valued at cost less any deprecia-
tion component included in the cost.  The dollar amounts
will vary slightly from one alternative calculation to
another.  These are representative.  In addition to the
capital items listed below there will be other costs
associated with functions that might be performed at
another location and added to the manufacturing cost just
prior to sale.  These would include corporate administration,

selling, research and other general expenses.  An allocation
of about 1/2% of sales income less raw material cost, or
$270,000, has been used for the cost component of general
and administrative functions and  $90,000 has been allocated
for capital associated with these functions.  These data
have been expressed as rounded totals in Table 14.

     Materials and supplies             $ 250 M

The grouping in Table 14 shows the relative contribution of
the various components of the overall installation to the
capital as total capital in column two and as capital cost
per annual ton in column three for unit comparison with
other processes.  Column four shows the relative contri-
bution to operating cost per ton of product.  The Allowances
from Table 13 were spread proportionally among the groups.
5.1.2     Manpower
The process was examined in detail and the duties of the
operators were listed in order that a good estimate could be
made of the number of people needed to operate four process
trains on an around-the-clock basis.  Table 28, Section
10.7.1, presents a listing of example duties for the process
                      -132-

operators.  A schedule of three eight-hour shifts per day
was chosen with a crew manning a shift for seven days, being
off for two days and then coming back on the next shift.
With this 7 and 2 arrangement four crews provide continuous
full time coverage.  There is one 3 day time-off period for
each crew every month.  Others on the 7 and 2 schedule would
be the plant guards, the quality control technicians, the
operators of the steam plant, and other utilities and a few
individuals from the service station, or motor pool, and
from the Maintenance Department.

On the basis of the plot plan, utility requirements, esti-
mated plant capital and the process manning the additional
manpower to adequately staff the entire complex was estimated
based on general Company experience and on the current
personnel list of a similarly sized independent operating
unit of the Company at a particular location.  A job listing
for this complex is given in Table 27, Section 10.7.1.

Table ISA below shows a summary of manpower by department
and section or function.  The data are further subdivided
into broad classifications of skills or wages to facilitate
analysis and development of alternative manning plans.  The
total personnel for this complex will be well over  500
people.  For purposes of economic evaluation the maintenance
personnel have been subtracted.  Their costs are included
in the charges for maintenance, described in Section 5.1.1.2.
An alternative to including maintenance men in the  total
personnel list would be to have the maintenance done by
outside contractors.

It could be expected that a plant such as this might start
out with one process train plus appropriate utilities and
services.  Personnel would be scaled accordingly.  During
the start-up, additional services manpower could be ar-
ranged for with the prime contractor, and a smaller Admin-
istration Department could handle the plant needs.  After
all units were on stream and personnel became more experi-
enced the spectrum of jobs could also change.  An example
might be a reduced requirement for supervisory personnel
in the Utilities Department.

Several functions are shown in Table 27, as more or less
secondary to the main personnel assignments.  Local condi-
tions for a particular plant would determine if these or
other jobs could be given peripheral importance.  Examples
are:

          Public relations and ecology planning,
          Office manager, receptionists, person responsible
          for answering the general plant telephone,
          Fire protection, first aid and industrial hygiene
          sections.  Local municipal and private participa-
          tion is assumed.

In addition, a large degree of flexibility should be built
into the jobs in the Services Department to provide efficient
response to changing requirements.

In the economics program in Section 10.7.2 the total person-
nel, excluding maintenance, for each labor classification
from Table ISA was used as input.  In Table 15B, the wage range
for each group is listed and the annual costs of labor by
skill and department are estimated and totaled.  These totals
are rounded and were increased by $24M above the labor shown
                         -135-

in the program to allow for a wide variety of miscellaneous
services.  The $24M was taken from the water and refuse
disposal estimate so that the total cost for sale is not
affected.  Examples of some of the miscellaneous services
that would be performed by the listed personnel or others are;

     —   Miscellaneous receiving, warehousing/ and
          package delivery,
          Laundry and safety supplies service,
     —   Recovery of salvageable materials,
     —   Temporary employment programs  (summer painting,
          contract yard cleanup and repair service,
          training programs).

5.1.3     Unit Ratio Based Costs
The single largest cost item is the purchased coal used as
feed to the chemical leach process.  Detail pertinent to the
coal balance is given in Table 16.  The other raw materials,
utilities and waste streams can be related to the coal
throughput, and for convenience these have been expressed
as a fraction of the product coal, less moisture.

Most of these inputs are identified and listed in Figure 1,
Block Flowsheet, Section 4.1.2 and in Figure 29, Utilities,
Section 4.8.3.  These have been tabulated in Tables 17A & 17B,
wherein are shown the units, the number of units used hourly
in one process train, the value of a unit and the number of
days of inventory for each item.  Table 17A utilizes metric
units and 17B conventional engineering units.  The basis for
the unit ratios is the product coal from the last column in
Figure 1, Block Flowsheet, less moisture and binder.  The
unit ratios were rounded by about 2% in the direction of
increased cost for some of the items other than coal
received and ash loss.

The following were taken directly from Figure 1:  coal
received, oxygen, sulfuric acid, naphtha, binder, sulfur
credit, fuel coal, and iron sulfates disposal.  The ash loss
is taken as the initial pyrite content less the pyrite and
iron and sulfur-containing residual salts left from the
reacted pyrite without correcting for the oxygen component
of the sulfates.  The nitrogen produced was taken as a
weight ratio of about 3:1 to the oxygen.  Approximately one
tenth market value was assigned to nitrogen for by-product
credit.

A term was entered to allow for miscellaneous chemical agents
as defined in the table.  This was set to be somewhat of the
order of cost magnitude of the smallest raw material, the
solvent.

The amount of water treatment plant effluent and the cool-
ing tower blow-down disposal or waste side-stream are given
in Figure 29, Sector 2204.  Disposal costs were taken arbi-
trarily as equal to one half the average water cost.  Ash
from the fuel coal is also listed in Figure 29, Sector 2100.
The costs of disposal of ash and sulfates refuse listed in
tables 17A and 17B are nominal values used for landfill.
The sulfates refuse cost allows for a thin membrane lining
for the landfill area(15'16'.

The unit costs in Table 17 were chosen from published and
private sources for 1973 and 1974.  The inventories were
generally taken as less than the design specification
capacities.

5.2  OPERATING COST ESTIMATE

5.2.1     Basic Conceptual Design Costs
A proprietary universal economic evaluation program  (UEEP)
was used to develop an estimate of typical operating costs
at capacity for the plant utilizing the values presented in
the preceding sections.  An example of the detailed computer
printout is given in Section 10.7.2 in conventional engineer-
ing units.  Tables ISA and 18B summarize the data.

Table ISA summarizes the cost items and gives the annual cost
per ton of product coal on a dry basis, and as sold includ-
ing binder and about 4% moisture.  The coal forwarded to the
plant boiler house as fuel and the ash loss are treated as
costs because they constitute a consumption of the purchased
coal.  An upward rounding of 0.9% in the unit ratio of
coal-received to coal-product required an increase of 11%
in the ash and coal losses in the cost estimate to balance
the coal accounting.  The remainder of the coal appears in
the product.  When this remainder is subtracted from the
total cost, a treating cost is obtained.

Table 18B shows the sales income and several profitability
measures using the cost data of Table ISA.  The data for
return on total capital before taxes (ROTCBT), or return on
investment  (ROI), are further plotted in Figure 30 to show
the impact of variations in direct fixed capital, selling
price, or production rate.  The base case shows a 12.2% ROI
at a sales price of $28.00 per ton, dry basis, for the capital
level presented in Section 5.1.1, i.e. $146 million DFC.
From Figure 30 it can be determined that to obtain a 20% ROI
it would be necessary to increase the price by 14% to $32
per ton or reduce the DFC by 25%.  A 20% decrease in produc-
tion rate for the base case DFC and price would result in an
ROI of 6%.

5.3  COMPARISON WITH OTHER RELATED PROCESSES

5.3.1     Criteria of Performance

There are a large number of processes being investigated
that will bring about better utilization of coal or reduce
the sulfur oxide pollution from coal combustion.  Several
of the yardsticks used to compare these processes are given
below with comments and data from the chemical desulfuriza-
tion process.

Engineering feasibility — This conceptual process design has
been shown to be completely feasible and can be used as a
basis for development of detailed engineering plans and
ultimate construction.

Sulfur removal efficiency — This process does not remove
organic sulfur, and it may leave a residual of up to 0.1%
sulfur as free sulfur and sulfates.  This places it between
coal conversion and mechanical cleaning in sulfur removal
ability.  For a wide range of coals this would be ample
beneficiation(2'15).

Commercial practicability — Coal beneficiation has the ad-
vantage that it can be performed in large volume production
facilities, the product can be sold for use in existing
large and small facilities without need for costly remodel-
ing, the cleaned coal can be stored outside for use, and
its cost for consumption varies directly according to the
output of the using facility.

Thermal efficiency — The following approximate calculation
shows close to 90% thermal efficiency for the overall proc-
ess from run of mine coal to cleaned and crushed product
coal.

The actual thermal efficiency will depend on the manner of
calculating the heating value and the amount of water dried off.

areas of the country where coal with a fairly high ratio of
pyrite to organic sulfur content is available and coal com-
bustion facilities exist, the chemical desulfurization process
offers the following capital investment to power ratio:

5.3.2     Closely Related Process Studies

It is very important that similar bases be developed when
interpreting different studies, and that major differences
be recognized when close comparisons are being made.  The
following studies are related to the process design pre-
sented in this report but the bases and methods are enough
different that a meaningful quantitative comparison cannot
be made using the reported data.

University of Michigan — A study made by a faculty team of
the College of Engineering at the University of Michigan for
the Electric Power Research Institute  (EPRI) presents a
detailed comparison of a large number of clean coal utili-
zation processes

The University of Michigan study presents a flowsheet, capital
estimate and operating cost calculation for the reported TRW,
Inc., process   , and it includes economics using a different
capital estimating method and costs estimated on the basis
of the Federal Power Commission Supply Task Force Utility
Financing Method.  For a 10,000 short ton/day plant the
U of M EPRI study reports total capital of $146 million
including working capital, interest during construction and
start-up costs.  The annual cost for 330 production days
including return on rate base, Federal income tax, depreci-
ation and net operating costs amounts to $78.7 million the
first year, decreasing to $61.7 million the eighteenth year.

Dow Texas Division — A cost analysis of the TRW process was
developed by personnel of the Texas Division of The Dow
                 (18)
Chemical Company     for a 2400 short ton/day plant having
approximately the same flowsheet as the U of M EPRI report,
i.e. only that part of the process from the initial conveyor
to the mixer to the final product storage but excluding
compaction of product fines and detailed waste sulfate pro-
cessing.  This report showed a capital investment of $29.5
                     -149-

-------
million for the smaller plant and a conversion cost of about
$10/short ton for 355 operating days annually.  The M. W.
Kellogg Company cost models were used.

Kennecott Copper Corporation — A closely related Oxygen
Leaching Process is under development at the Ledgemont Labor-
                                      (19)
atory of Kennecott Copper Corporation    .  The reported
process uses more oxygen and does not make elemental sulfur.
A generalized block diagram of the process is given and pre-
liminary scoping economics show somewhat lower capital and
operating cost:
Inc., process.
                                          (17)
operating costs than the U of M EPRI study   ' for the TRW,
Research Triangle Institute — A survey of stack gas scrub-
bing alternatives by the Research Triangle Institute
for a wide range of coal fired steam and power generation
plants showed that, for more than 75% of existing industrial,
commercial and institutional boilers, de-pyritized coal at 40
to 60C/MM Btu additional cost would be competitive with stack
gas cleaning.

The Institute also estimated^  ' that 23.2% of the coal
currently being mined could be satisfactorily processed
by mechanical and chemical means to meet present source
performance standards.  The data are summarized in Table 19.
These data are based upon the total domestic coal base.
Application of a coal desulfurization process which removes
only inorganic sulfur, such as the TRW process, would be
restricted by'local and/or regional coal characteristics
and sulfur removal requirements.

      6.0  PROCESS ALTERNATIVES AND THEIR ECONOMICS

The Base Case capital estimate was built up from a compre-
hensive base of experience within The Dow Chemical Company
and by the vendors whose quotations were used.  At the
levels of development and design represented the precision
is reliably estimated such that the capital cost figure
has an 80% probability of lying between $120MM and $180MM.
This was on the basis of 1973 dollars and economic conditions
projected two years using historical norms.  It does not
include the effects of the increased inflation of 1974 and
beyond.

The alternatives in this chapter were not "engineered," and
this must be taken into consideration.  However, the various
cases do show the relative effects of the various hypothet-
ical alternatives.

The development of the economics for alternatives in this
chapter utilizes the regions indicated in the Block Flow-
sheet, Figure 1, to more readily identify and emphasize the
effects.  Four regional groupings were used with the essen-
tially non-chemical processing regions combined in one group.
These are shown below with the included regions or sectors
and showing the proportion of treating cost represented as
a result of the calculations.

data were distributed, the alternatives are explored accord-

ing to the above four regional groups.

-------
6.1  BASE CASE, CASE 1

6.1.1     Case 1
The base case economics data are displayed in Table 20 in
regional groups.  Care was used in proportioning the data
among the groups, and the salient features of this propor-
tioning are given below.

Process Capital — The sector totals were all taken from
Table 13.  The fraction of each group to the total is given.

Other Capital — Proportioning of the other capital items
was according to overall usage of the process region.  These
were developed generally as follows:

     Buildings and Miscellaneous — mostly buildings and
     construction related to chemical processing sectors.

     Site and General — Coal Handling region largest in
     area.  Administration buildings, railroad facilities,
     road and yard development were heavily assessed against
     Coal Handling.  Maintenance shops more evenly propor-
     tioned.

     Oxygen Plant — all to Leaching.

     Utilities — predominantly steam plant plus water
     supply treatment and cooling.  Proportioned according
     to utility usage.

     Allowances — proportioned according to Process
     Capital plus the above Other Capital.
                       -155-

-------
Working Capital — Inventories were proportioned according
to appropriate region.  Cash, and Accounts Receivable were
essentially all assigned to Coal Handling.

Capital Related Operating Costs — Depreciation was re-
estimated from Table 14 modified by the capital proportion-
ing discussed above.  Maintenance, Insurance and Taxes
followed the percentage assignments used previously, viz 4%
and 2%.  Labor was proportioned from Tables 15, 16 and 27.
It is designated as capital related because, for large
incremental changes in constructed plant capacity, the labor
will be proportional to the fixed capital.  General and
Administrative costs followed the labor pattern with a
slight increase in the main chemical processing regions.

Unit Ratio Based Operating Costs — These costs were assigned
according to consumption or usage.  Fuel coal was propor-
tioned according to steam usage.  Ash loss represents the
weight loss due to FeS- removed, and was all assigned to
Leaching.  Water supply, disposal of treatment plant ef-
fluent and cooling tower "blow-down," steam plant ash
disposal and waste sulfates disposal, and miscellaneous
services costs were spread according to usage.

Coal to Product — The entire cost of that proportion of
the feed coal that ultimately ends up in the product was
assigned to Coal Handling so that the chemical processing
costs could be clearly identified.  When the feed coal to
product is subtracted from the total operating cost, the
process cost contribution of each region is shown.

6.1.3     Effect of Production Rate
Estimates for the capital and operating costs for plants
of different sizes may be made using the subtotals from
Table 20.  The development and use of such an estimating
procedure is shown in Table 21.  The assignment of scaling
exponents is shown with the capital cost data for the
Base Case.  The Coal Handling and Waste Sulfates regions
were combined as were the Leaching and Extraction regions.
The capacity of the Coal Handling and Waste Sulfates regions
could be increased by utilizing larger equipment and so these
were assigned a scaling exponent of 0.7 for scaling up and
0.65 for scaling down.  The Leaching and Extraction regions
are so dominated by the reactors that it is likely that they
would be scaled in 100-130 T/hr increments with some sharing
of equipment, so a scaling exponent of 0.85 was assigned.
The Other Capital is made up of components that could be
expanded efficiently, so 0.65 and 0.7 exponents were used.

For the alternative cases in the lower section of the table
production rates of one half and two times the Base Case
were chosen.  Thus, the Coal Handling and Waste Sulfates
regions were estimated as follows:
Production Rate                                Process Capital
    M T/yr                 Calculation         	$MM	
     3300                                            33.4
     1650     33.4 x  (0.5)0'65 = 33.4 x 0.636 =      21.2
     6600     33.4 x  (2.0)°'7° = 33.4 x 1.63  =      54.4
The Capital Costs were estimated for each group and totalled
down and across.  Then the production costs were estimated.
                        -159-

-------
The Capital Related Costs  (CRC) from Table 20 are shown for
the Base Case and compared to total capital  (TC).  Ratios of
CRC/TC of 0.18 and 0.20 were obtained and used.  The Unit
Ratioed Costs  (URC) are not much affected by production rate,
so were used as constant $/T values for all cases.  These
costs were estimated and totalled.

A plot of the effect of production rate for plants operating
at design capacity is shown in Figure 31.  The open points
represent production multiples of 1,2,1/2 and 1/4 times the
Base Case.  The short steeper curves represent the effect of
production rate changes on the operating cost for the base
plant and a half-size plant without changes in respective
design rate capital, i.e., the Capital Related Costs remain
constant on an annual basis while the Unit Ratioed Costs
remain constant on a unit basis.  The net result of these
calculations is to show that the costs are not greatly
affected by volume of production in the vicinity of the
Base Case, e.g., for a 100% increase in rate, costs decreased
only 9%; for a 50% decrease in rate, costs increased 13%.
For smaller plants, debottlenecking can appreciably reduce
costs.

6.2  COMPREHENSIVE ALTERNATIVE CASES, CASES 2, 3 and 4
Cases are developed below showing how interrelated process
changes and accounting procedures could greatly reduce
the apparent cost of installing chemical desulfurization.
Example calculations for the first three cases are given in
Section 10.7.4.

Assumptions:
The following letters are used in the summaries of capital
and cost reductions to designate the manner in which the base
case capital and operating cost items were adjusted:
     (a)  eliminate, facilities or personnel in similar jobs
          already exist
     (b)  greatly reduce, share personnel or facilities after
          modification
     (c)  accept an allocation of a larger facility
     (d)  adapt and use a different processing step or system
6.2.1     Coal Handling
Case 2 CH
Assume that the chemical desulfurization process is installed
on the site of an existing complex that has coal handling
facilities.  The new facilities must bear their share of
the new capital and operating costs.  An example of such an
installation is given in the Appendix, Section 10.7.3.
Arbitrary, but realistic, assumptions have been chosen, and
a case is built up for a plant with over twice the coal
receiving capacity of the base conceptual design with coal
washing and 'some drying facilities, plus storage and pulver-
izing facilities at an on-site powerhouse that will consume
up to 20,000 tons of coal per day.

No new receiving and storage areas or labor will be needed.
Some conveying required to new site.  Pulverizers modified

to grind wet fines.  Grind only through 14 mesh   .  Share
dryers but only dry down to about 13.4% moisture rather than
4%, thus reducing drying capacity by as much as 50%, e.g.,
with 22.8% moisture from the final coal filtration,

     22.8 - 4.0    18.8
                        = 0.50
Eliminate compaction and use binder fluid described in
Section 4.4.2.4 to minimize dust loss in transfers.  Share
product storage and build storage equivalent to 50% of base
case.  Utilities and services supplied at 70% of the cost
used in the Base Case.

Case 3 CH
If it is assumed that chemical desulfurization is being
added to the coal preparation complex of a large coal user,
e.g., a utility or coking plant, for the purpose of decreas-
ing the total sulfur content of the coal while improving the
yield (usable coal/coal received), then it is conceivable
that the entire operating cost of the Coal Handling region
could be absorbed into other accounting functions.

This is not too extreme an assumption.  In such a large
complex essentially all of the coal handling facilities,
working capital, personnel, and services would already exist
or be able to be assembled with little more than normal
project maintenance, service costs and disruptions.
                 Case 3 CH, Coal Handling   nil $/T
See also Cases 3 CP and 3 U which approach this concept
differently.
                         -165-

-------
Case 4 CH—Merchant Coal
In the above context chemical desulfurization could be
added to a large merchant coal preparation plant with
relatively minor cost increases for Coal Handling.  In
this case coal fines stabilization could be employed as
described in Section 4.4.2.4.  Further elaboration would
be needed but it is possible to adequately protect against
fine coal losses in storage, transferring and transit for
less than $0.50 per short ton

-------
6.2.2     Chemical Processing
Case 2 CP
Continue developing the Chemical Processing steps to match
the Coal Handling of Case 2 with the same assumptions where
applicable; 14 mesh topsize coal, utilities and services at
30% lower cost.  Analysis of the job functions of Table 27
shows that more than half of the Administrative and Ser-
vices personnel would not be required for this case, as
either these services would not be needed for selling and
shipping coal or they could be obtained from personnel
already employed by the utility.  The net reduction in
labor is estimated as 25%.

Other alternatives under development or contemplated are
included in the discussion by region below.

Assumptions:
Leaching — Very fast reacting coals    and complete foam-
ing control in the mixer greatly reduce the required number
of reactors and cut process capital in half (See 6.3 Case 5)

Extraction — Elemental sulfur remaining after the leach
step is cut in half by control of acidity and oxidation
                                (19)
conditions in the leach process    .  A solvent with a very
high sulfur solubility is used above 120°C in counter
current flow  '   .  Capital of Sector 1400 is cut in half.
Waste Sulfates — Part of the waste is reprocessed to
recover salable products.  See Table 22    .  The remai
is disposed of in an abandoned section of a nearby deep
mine    .  One half of the capital is removed by elimin
or by charging its cost to the reprocessing.

There would be an Increase in product tonnage corresponding
to the fuel coal equivalent of the lower steam requirements.
Assume that this amounted to 30% of the fuel coal, 90M tons
per year, or an increase of 2.7%.  From Figure 30 this
would represent about a 1% improvement in ROI.  The profit
before tax is $18,911 M/yr at 12.3% ROI (Table 19), so for
an increase of 1% to 13.3% ROI, for 3300 M T/yr the
improvement could be :

Case 3 CP
Using the assumptions for Case 3 CH Coal Handling, i.e. decreas-
ing the total sulfur content while improving the coal yield,
the original large plant might be facing a situation where
an appreciable fraction of the coal from the existing mechan-
ical separation facilities could not be used.  In this event
some value for the unusable coal at that point plus the cost of
disposal could be credited to the chemical processing facility.
Example calculations for such a hypothetical situation are
given in Case 3CP, Section 10.7.4 with a suggestion that a
credit of $2.00/T be used in lieu of a larger calculated,
but indeterminate, credit.

Case 3 U
The ideas presented in Cases 2 and 3 are approached from the
standpoint of overall coal costs to the utility plant in
Case 3 U.  The details are given in Section 10.7.4 and the
cases may be summarized as follows:

existing plant and provides for some improvements in technology,
Case 3 uses the same technology but charges all of the coal

handling to the plant plus another  $2.00/T for processing the
middlings.  From the example calculation of Case 3 U it is
apparant that the economics and accounting practices for the
rest of the plant play an important part in the determination
of the treating cost for upgraded coal.

Case 4 CP — Merchant Coal
A complete coal preparation plant could take advantage of
the same type of cost reductions described in 2 CP and 3 CP;
however, for this example a less optimistic view was chosen —
no appreciable reduction in Utilities Capital and Cost and
only 25% reduction in sulfur credit and all other capital
and cost items.  See 10.7.4 Case 4 CP.

                           Coal       Chemical
                         Handling    Processing   Total
Base Case,       Case        1           1
                 Cost      3.59         9.88      13.47

Utility Cases - costs added to existing plant for chemically
desulfurized coal:

All facilities bear their share of the cost and share
utilities, fast reacting coal, new developments in extrac-
tion and sulfates reprocessing.
                 Case      2 CH         2 CP
                 Cost      1.37         6.85       8.22
                         -172-

-------
As above, but chemical desulfurization plant is not charged
for coal handling as plant wishes to decrease sulfur, improve
yield, so allows credit for less fuel coal consumed and
for refuse saved.
                 Case      3 CH         3 CP
                 Cost       0       6.85 - 2.00    4.85

Utility Case - Costs spread across all coal used:
Above case stated on the basis of the entire coal handling
and cleaning operation for the utility plant.
                 Case      3 U CH       3 U CP
                 Cost       2.91         5.36      8.27

Merchant Case - costs added to existing plant for chemically
desulfurized coal:

Add to existing facilities, fast reacting coal as in 2 CP
but less optimistic cost reduction.  Use 3 CP type credit.
                 Case      4 CH         4 CP
                 Cost      0.60     7.73 - 2.00    6.33

The Merchant Coal example is an illustration of how the
foregoing discussion and calculation summaries can be
readily used to build a case to a certain requirement.

The above combination cases and others are plotted in
Figure 32 and further described following the plot.

If a chemica.1 desulfurization plant were installed at a
utility plant distant from the coal fields the freight cost
of the material later disappearing as ash loss could raise
the cost of this item 50% or more.  Proximity to a source
of waste sulfuric acid could provide a compensating cost
reduction.

Using flocculants, moving the water wash ahead of extrac-
tion and feeding drained extraction filter cake to the
dryers    could result in some savings in the filtration
and decantation sectors and reduce steam costs for driving
off naphtha instead of water.  These savings would be
balanced against flocculant cost and increased naphtha usage
(less naphtha fuel value).
Figure 32 shows a bar graph of several combination cases.
An equivalent coal price of $8.80/T was used for all cases
except that where there is a $2.00/T credit for a Case 3 CP
situation, this is portrayed as decreasing the coal cost to
the process.  A table summarizing the calculations is given
as the second page of Figure 32.  Following are examples of
what is shown in $/T:

A number of such cases can easily be approximated from the
various unit costs given in this report.  Such approxima-
tions can indicate the value of obtaining further data.
Cases involving various iron pyrite levels are given in the
next section.

6.3  LEVEL OF IRON PYRITE, CASES 5 TO 10

The costs in this section reflect a more detailed analysis
of process variables and equipment sizes than those pre-
sented in the previous sections of this chapter.

Based on the computer printout represented in Table 8,
Section 4.2.4, the data were plotted in Figure 33 as
the log of the weight fraction of residual FeS2 versus the
log of the number of reactor sections.  For the system of
continuous reactors in parallel used in the base case the
data for the mixer and the ten well mixed sections in the
reactors were taken from stepwise output internal to
Program B, described in 10.4.1.

About 14% of the FeS2 is reacted in one-half to one hour in
the mixing tank at 102°C  (215.6°F).  Then in the first section
of the parallel reactors the reaction is brought to about 43%
of completion in another hour.  The reactors have final condi-
tions of 5.6 kg/cm2  (80 psia) and 150°C  (302°F).

Described below are several cases for differing FeS2 content
in the feed or differing degrees of removal.  The same coal
rates were assumed so there would be no change in the Coal
Handling region.  Also, for 6.7% FeS2 or less, the liquid
to coal ratio was assumed to be unchanged, so there would be
little or no change in the filtration, extraction and
washing equipment.  The 20% foam disengaging volume in the
reactors was maintained for volumes less than the Base Case.

The adjustments that could be expected in capital invest-
ment are developed in Table 23.  The factors by which the
major chemical equipment in affected sectors differs and

-------
the factors to be used for scaling the cost of these sectors
are given.  Subtotals for each region are shown and the
total fixed capital is given.

The operating cost changes are developed in Table 24.  The
changes shown in Table 23 are expressed in Table 24 as per-
cent change in FeS2 removal and fraction change in Chemical
Processing capital.  The use of these is detailed in the
description at the left in the table.  The capital related
cost changes predominate.  The cost changes related to coal
consumed for fuel and for purchased power are tied to equip-
ment changes and so were adjusted according to capital changes
All other costs were calculated on the basis of FeS2 removal
changes.

The rationale for each of the various cases of different
starting FeS- levels or different degrees of removal is
given below.  The operating cost reduction estimates follow
the pattern of Table 21.  The effect is shown in Figure 34.

Case 5 	 6.7% FeS2, 90% removal
                           0.67% FeS2 residual
From Figure 33, 50% of Base Case reactor volume is re-
quired.  The reactors were reduced to one-half Base Case
capacity.  Distillation and waste sulfates equipment were
little affected by the 5% reduction in FeS2 removal.  In
practice, the filter would probably be Base Case size and
more filtrate would be recycled so that a more concentrated
solution could be fed to the evaporator.

-------
Case 6	 6.7% FeS2, 14.5% removal
                           5.7% FeS2 residual
From. Figure 33, no reactors used other than the mixer.
An allowance of $2MM was made for the solution regeneration
facilities for a hypothetical case where all of the reaction
occurred in the mixer.  The distillation and waste sulfates
sectors were reduced to 20% of the Base Case as were
utilities.

This case and Cases 8 and 10 are used to define the lower
limits of sulfur removal in Figure 34, the plot of the
cases in Table 23.

     Capital Reduction                                   $56 MM
       -as percent of Chemical Processing, 48%
     Operating Cost Reduction                          $5.38/T

Case 7	 3.35% FeS2, 90% removal
                          0.34% FeS2 residual
Assumed one half the initial FeS2 content and the same
percent removal as in Case 5.  Should require 50% of Base
Case reactor volume, but 40% was assumed because it should
be possible to recycle iron sulfate back through the mixer
to build up its concentration.  Distillation and waste sul-
fates capital and cost would be about half of Case 1 because
of smaller absolute levels of FeS2 dissolved.

     Capital Reduction                                 $31 MM
       -as percent of Chemical Processing, 26%
     Operating Cost Reduction                          $3.06/T

Case 8	 3.35% FeS2/ 14.5% removal
                           2.86% FeS2 residual
                        -180-

-------
This case bears the same relationship to Case 7 that Case
6 does to Case 5, i.e., a definition of the lower limits of
sulfur removal for Figure 34.

     Capital Reduction                            $62 MM

                           0.67% FeS2 residual (to <0.4%)
Twice as much iron sulfate solution required to maintain
the same stoichiometry, doubled equipment size for all
Chemical Processing except washing, filtration and vent
scrubbing as well as for utilities in Chemical Processing.

          —by proportion, 11.5% FeS2 residual
          —used,           6.7% FeS2 residual
Case chosen to augment Case 9.  No data have been presented
for this particular case but it is believed that such a high
level would provide much exposed FeS2 to be dissolved in
the mixer.  This could be as much as 50% in three times
the residence time in the mixer.  Data for some coals show
over 80% FeS~ reacting in the first hour of the reacting
time<3'.

6.4  MISCELLANEOUS COST EFFECTS

Aggressive process development will undoubtedly decrease
the overall capital and operating costs for this process,
excluding the effects of inflation.  As fuel prices con-
tinue to increase it should be possible to show increasing
improvements in the relative economics of desulfurization.

Capital Reductions — From Table 20 it can be seen that
annual Capital Related Costs amount to about 15% of Fixed
Capital.  A savings of $1 million in capital will be re-
flected in $150,000 per year, or 45C/T, in operating costs.
Thus the potential annual benefit of eliminating the 20%
foam disengagement volume in the reactors and decreasing
the liquid to solids ratio slightly in Sector 200 would be
(see Section 10.6.2, sheets 4 & 5):

     $21.4MM(1-(0.8)°'7) = $21.4MM(1.0-0.856) = $3.08MM

At 45C/T per $1MM reduction this would be $1.39/T.

The cost savings for capital reductions can thus be compared
with corresponding required operating cost increases.  As
an example, assume the filter sizes in Sector 800 can be
reduced by 40% by the use of flocculants and that redesigns
of Sector 700 would allow inclusion of a settler with no
increase in capital cost.

Projected capital related cost savings on reductions in
purchase cost of filters and accessories  (Section 10.6.2,
sheets 11 & 12):

     ($0.515MM x 4) (1-(0.6)°'7) x $0.45/(T)($1.OMM)
          = 2.6MM x 0.30 x 0.45/1.OMM = $0.35/T, saving
                       -185-

-------
First approximation for flocculant cost  (Section 4.4.2.2(a)
and Table 17b):

     0.05 Ib of flocculant/T x $0.50/lb = $0.025/T

The cost of using an effective flocculant appears to be
very favorable with respect to the potential cost savings
related to capital.  Data to allow a more vigorous evaluation
of attractive potential trade-offs should be obtained from
vendors' tests and pilot plant operations.

Raw Material Prices — The impact of price variation, and
of raw material usage changes, can be estimated using the
data in Table 17B and the desired price or unit ratio.

As can be seen, the impact of moderate price changes in the
non-coal raw materials is minor and the increases could be
balanced by an increase in by-product sulfur price.

Oxygen could have been included as a purchased raw material,
but at the low return shown in Table 18B it is unlikely that
a "make vs buy" study would show purchasing to be favorable.
This would need to be reevaluated if a higher return case
were anticipated.

Another case that should be examined but which is beyond
the scope of this report is the utilization of high sulfur
coal refuse for the steam generation plants.  In the base
case 79.2C/T, dry basis, represents product coal used for
fuel at raw material coal price, or $2.6MM per year.  This
will increase as coal prices increase; thus a cost of $2.6MM
per year could be expended in a merchant coal plant for the
operating cost of a suitable means to utilize high sulfur
coal, e.g. stack gas scrubbing or high-sulfur fuel com-
bustor techniques.  This would permit the large coal prep-
aration plant to take advantage of economies for a scrubber
system on a large steam generation plant running at a steady
rate     and to pass these economics along to the smaller
coal user for whom scrubbing might be impractical.

                        -187-

Cost Escalation — In addition to considering process
alternatives it may be desired to project costs several
years into the future in order to compare the Base Case
with other options.  Two cost indexes that are frequently
used by process engineers are plotted in Figure 35.  These
are the ENR Building Cost Index    , based on construction
wage rates and material costs in 20 cities in the U.S., and
                       (34)
the CE Plant Cost Indexv   , based on a variety of industry
data.  The year end index is published the first week in
January for the ENR Index and in April for the CE Index.
These are different from the annual averages    .  Figure
36 is a plot of the average value of bituminous coal, F.O.B,
mines    .  The data are given below.  The projections
reflect the thinking of cognizant departments of The Dow
Chemical Company.

       7.0  CONTINUOUS SIMULATION MODELING PROGRAM

7.1  INTRODUCTION

The purpose of this investigation was to examine the
chemistry of coal desulfurization in relation to the pro-
posed process with emphasis placed on the leach, regenera-
tion, and iron sulfates removal steps.  There were two ways
to approach this problem:   (1) Each process area would be
examined separately and conclusions would be drawn.  These
individual conclusions would then be brought together and
modified if necessary to account for their interactive
effect on the entire process.   (2) Each area of interest
would be investigated separately but in such a way that
the impact of any changes on the rest of the process would
be reflected.  This latter approach was selected as the
better way to study the process.

The link used to tie the process areas together was a mass
balance simulation model.  Further, in an effort to make
the simulation more realistic, it was developd as a tran-
sient state mass balance instead of a steady state mass
balance.  The transient state model adds additional insight
in several ways:   (1) It shows how accurate steady state
assumptions are and it shows the time required to reach
steady state from start-up.   (2) The effect of condition
changes during operation can be examined and the time re-
quired to reach new steady state conditions determined.
(3) The transient state simulation will better illustrate
the effects of critical chemical parameters and stream
components on the entire process.   (4) The model can be
modified to include and optimize capital and operating costs
under any constraints that are imposed on the process.
                          -191-

-------
The material balance model was developed using the Con-
tinuous Simulation Modeling Program  (CSMP).  CSMP is a high
level IBM programming language that minimizes the amount
of programming required by the user.  For example, efficient
subroutines are available for the performance of numerical
integrations, determination of roots in implicit equations,
generation of impulses, random numbers, debugging, etc.

This program was written to output all stream components,
molar flow rates and the molar amounts.  These molar quan-
tities were then used as a base for calculations related to
the coal desulfurization chemistry.  A copy of the program
is listed in the Appendix, Section 10.8.1.  Because of
storage limitations this program listing is not complete
for handling all variations that were simulated.
                      -192-

7.2  BASIC PROCESS EXAMINATION
7.2.1     Simulation Model Assumptions
The building and use of a model to simulate the chemistry of
a process provides one immediate advantage in that it shows
areas where additional data are needed.  This study was no
exception.  In the building of the model, assumptions had
to be made as to where data were lacking.  The use of the
model indicates how sensitive the process is to variations
in these assumptions.  Generally, the areas where assump-
tions had to be made in the absence of data can be classified
into one of two types:  (1) Those assumptions that had to
be made about the process in order to develop the material
balance.   (2) Assumptions made about the chemistry so that
inferences could be extended to the process.  Those that fit
the first category will be discussed in this section while
those relating to process chemistry will be discussed in
sections wherein they pertain.

Solution density and specific heats have to be assumed in
order to calculate volumetric flow rates, volumes, and
the rate of iron sulfates removal from the evaporator-
filter system.  Also a better knowledge of the solution
density variation as a function of component concentration
should be obtained because it may have a significant effect
on the residence times and, therefore, on the product coal
quality.

One of the features of CSMP is its ability to print any
calculated quantities in table and/or plot form with a

minimal amount of user programming  (no format required).
Figures 31 a, 37b, and 38 show some typical output for the
iron sulfate stream flow rates and amounts as a function
of process operating time.  The quantities shown in these
figures are simulated results based upon the proposed coal
desulfurization plant design.  The initial conditions and
flow rates are based upon the steady state quantities used
in the process design.

The cyclic shapes of the curves in Figures 37a, 37b, and
38 are caused by residence times in the different vessels.
The small irregularities are caused by vessels having
small residence times, while the large cyclic variations
are caused by the ten hour residence time for the reactors.
Note that these cyclic effects have begun to dampen as
the time of process operation increases, indicating that
the process is approaching steady state.  Outputs for all
streams were examined to see if there were any excessive
buildups or depletions.  No obvious problems of this nature
were observed.
7.2.3     Location of Iron Sulfates Removal Operation
The location selected for the removal of excess iron sul-
fates is quite important, as it will have a significant
effect on the efficiency of the oxygen usage and the
efficiency of the energy used in evaporation.  Oxygen is
added to regenerate ferric ions so that the leach process
can proceed at a favorable rate.  When ferric ions are
removed from the process, the oxygen use efficiency de-
creases because the removal of one mole of ferric ions from
the process means 0.25 mole of oxygen is wasted.  Conse-
quently the optimal iron sulfate removal location would

be one where conditions were most favorable for ferrous
sulfate precipitation  (to minimize evaporation costs) and
least favorable for ferric hydroxide and ferric sulfate
precipitation.  There are two general areas in the process
where the excess iron sulfates can be removed:  (1) somewhere
in the recycle stream from the reactors to the mixer  (2) in
the mixer effluent.  On the proposed flowsheet the chemical
compositions at these locations are best described as that
of stream #9 and #19 respectively.  The process design calls
for removal of coal by filtration of stream #16 followed by
evaporation of the filtrate, stream #19, with subsequent cooling
and removal of iron sulfate crystals by filtration.  There is
good reason for choosing this location.  Figure 39 shows the
product Kw  [Fe  ][H ]   as a function of process operation
time (See Appendix Section 10.8.2 for a discussion of iron
precipitates and the conditions of their formation as well as
the definition of Kw).  This product gives a relative indica-
tion of the degree of stream, or vessel, liquid saturation as
a function of process operation time.  Stream #9 has a much
higher solubility product than stream #19.  Figure 40 is a
                   (21)
Posnjak and Merwin     ternary diagram that has the 90 hour
region of process operation marked as an overlay.  Note that
the conditions in stream #9 place it in a region where pre-
cipitate is formed, whereas stream #19 is in a region where no
ferric sulfate forms.  It is clear from these figures that con-
                 3+
siderably more Fe   would be removed if the evaporation-
filtration operation were located after the reactors.  By
waiting until this ferric ion rich solution is recycled
through the mixer, several things are accomplished.  Ferric
ions are depleted in the mixer during preliminary leaching.
The mixer effluent is now more rich in ferrous ion and
somewhat depleted in ferric ion, which means a minimal loss
of ferric ions with a maximum amount of ferrous ion re-
moved per unit of energy  (Figure 41) for evaporation.

This situation may even be further improved by placing a
surge tank between the mixer and the point where stream #16
is taken from stream #5.  The capital cost of such a tank
would have to be balanced against the savings of increased
oxygen usage efficiency.
7.2.4     Leach Solution Loss in Clean Coal
Figures 39 and 40 that were alluded to in the previous
discussion bring a potential operating problem to surface.
The ternary diagram shows a ferric sulfate precipitate
to be forming in stream #9.  Also, the chance of ferric
hydroxide forming in stream #9 is very high.  The 25°C
                                      — 37      — 38 (22)
K   of ferric hydroxide ranges from 10    to 10       .
Bringing into account the high temperature and the high
                                                     -39
ionic strength of the process, the K   is probably 10
     -40                             p
to 10    (see Section 10.8.2).  This situation may be un-
favorable for several reasons:   (1) The ferric precipitate
may be removed with the coal at the F-400, F-600, and F-800
filters.  A water wash of the filter cake may solubilize
the iron sulfate precipitate, but it will probably mean
that it is converted to ferric hydroxide.  Possibly this
hydroxide conversion may be prevented if the initial wash
is a cold water wash, but data are not available to predict
this accurately.   (Section 10.8.2 discusses areas where solu-
bility data are still required.)   (2) The pyrite leaching
rate may be affected.  Ferric ions present as ferric hydrox-
ide will not leach pyrite as rapidly as ferric ions in
solution.  Possible remedies to this problem are:   (a) Run
the entire system in a more acidic environment from start-
up,   (b) Provide pH controlled make-up acid to the reactor
effluent.
                       -201-

-------
7.2.5     Stoichiometric Variations
The leaching of pyrite by acidic iron sulfate solutions is
not a new area of study.  This chemistry has been studied
extensively, as it is the principal cause of acid mine drain-
age in coal and copper mining areas.  However, in mine
drainage studies the goal was to determine the rate mech-
anism in order to inhibit the leaching rather than to
                                  (23)
enhance it.  Garrels and Thompson v    studied both the leach
and regeneration reaction chemistry and rates.  Their find-
ings are not in complete agreement with those of TRW.  The
TRW stoichiometry for the leach and regeneration steps are:

LEACH:
9.2Fe3++FeSn+4.8H00  ^ X 10. 2Fe2++9. 6H++0. 8S+1. 2S0.2~  (3)
                      ~"
REGENERATION:
           Fe2++H++l/402  ^ ^ Fe3++l/2H20               (4)

The reported findings of Garrels and Thompson are in
agreement on the regeneration step stoichiometry but not
in agreement with regard to the leaching step.  Their
proposed stoichiometry is:
            14Fe3++FeS2+8H20  ^ > 15Fe2++2S042~+16H+    (10)
The questions of interest are:  If the Garrels and Thompson
stoichiometry is correct, what process alterations could be
considered, and what type of products would be obtained if
the proposed process remains as designed?

Obviously, the absence of any intermediate sulfur product
would mean reduced capital and operating costs in the design.
If it can be demonstrated that a sulfur reaction product does
                         -202-

-------
not form or that operating conditions exist such that sulfur
will not form, then the sulfur solvent extraction opera-
tion can be eliminated from the process.  Some initial
calculations were done to see if the Garrels and Thompson
findings are feasible.  Section 10.8.3 shows how E_-pH
relations can be derived to study the findings of Garrels
and Thompson using thermodynamics.  Figure 42 is an E.-pH
plot that shows regions of stability for sulfur species.
In order to use this plot in conjunction with the CSMP
simulation of the process, the factors that determine the
stream or vessel E,  must be determined.  The H~O-02
system could be used to calculate the E, at the bottom
of the reactors because the high oxygen, partial pressure
would make that system the one that controls the En

          Eh = 1.23 + 0.0148 log PQ - 0.059pH            (11)

However, as the oxygen supply is depleted during the re-
generation of ferric ions, the ferric-ferrous system will
become the E,  controlling system(30)

Consequently, equation (12) was used to  calculate the Eh
since it provides the lower E, limit.

The ferrous and ferric quantities are known from the molar
flow rates and molar amounts  in the CSMP calculations, so
the solution E,  for different vessels and streams in the

process, since this is the part of the process where the
ferric ion quantity in solution has been depleted the most.
Even under these conditions the sulfate or bisulfate forms
of sulfur are most stable.  This information does not com-
pletely rule out the possibility of sulfur formation.  There
are other ways that two studies could arrive at different
results:

      (1)  While thermodynamic relationships show sulfur to
          be unstable, the kinetics may be slow enough such
          that sulfur is formed as an intermediate.  There
          definitely is a need for a more detailed rate
          study to determine the steps in the mechanism.
      (2)  The studies of TRW showed sulfur as a product in
          the batch tests.  Garrels and Thompson also
          observed sulfur when the ferric ion concentration
          was depleted.  In all cases pf continuous oper-
          ating experiments TRW reported a calculated sulfur
          amount based on the results of the batch tests.
          Perhaps the reaction does not go far enough to
          completion when the batch leach is near equilibrium
          and the ferric ion concentration is essentially
          depleted.
      (3)  It was suggested that coal may be acting as a
          reducing agent at these elevated temperatures
          with the coal being oxidized and sulfate reduced.
                                   °
                 2C + S04    ^    S  + 2C02 + 2e        (13)

          The change in free energy for this reaction is
          -7.28 kilocalories.  If this reaction occurs, it
          may be possible to remove the sulfur by adding a
          unit operation much like the cone precipitators
          used in copper cementation.  Here the coal could
                        -205-

-------
          conceivably be sprayed with a solution having a
          high E, .  The sulfur would either be spalled
          from the coal surface and oxidized or it would
          be oxidized and then leached from the coal.

The other difference in stoichiometrics is in the amount of
ferric iron required to leach the pyrite.  A CSMP simulation
was run using the proposed process and operating conditions
with Carrels' and Thompson's stoichiometry.  It was antici-
pated that the results would not be favorable, as 3.5 moles
of 02 are required to leach one mole of pyrite while 2.3
moles are required by TRW stoichiometry.  Figure 43 shows
the molar flow of pyrite from the reactors for both cases.
As expected, the proposed process only removed 65-75% of
the pyrite.  To compensate for this loss due to stoichiom-
etry, the amount of oxygen would have to be increased by
50%.  As long as the regeneration rate.is sufficiently
faster than the leach rate the reactor size would not have
to be increased.  A CSMP simulation with 48 Ib moles of
oxygen per hour flowing to the reactors confirmed this
assumption.

7.3  PROCESS AND OPERATING CONDITION VARIATIONS
7.3.1     Ferric  Ion Regeneration in the Mixer
One alternative suggested as a potential process improve-
ment is regeneration of ferric ions in the mixer.  Oxygen
would be added to the mixer with no change in pressure over
the mixer.  A CSMP trial was made to see if an increase of
the ferric to total iron ratio would increase the amount of
pyrite leached in the mixers and subsequently reduce the
amount fed to the reactors so that fewer or smaller reactors
could be specified.

The simulation results indicate that this alternative is
not favorable for this level of pyrite in the coal.  The
additional oxygen does increase the ferric to total iron
ratio, but it does not increase it sufficiently so that
the amount of pyrite remaining in the coal product is
reduced.  Figures 44a and 44b show the molar flow of pyrite
from the mixer and reactors as the time from start-up
increases.  These simulated results indicate that ferric
ion regeneration brings the mixer rapidly to steady state,
but the overall improvement in the clean coal product with
respect to pyritic sulfur is marginal.  One reason that
this modification appears to be disappointing is because
the additional oxidation is depleting the system of acid.
Figures 45a and 45b show the molar flow rate of acid in
the stream that recycles to the mixer and the molar amount
of acid in the mixer, respectively.  What is actually hap-
pening here is that the acidity in the system is now in the
form of ferric ion instead of free acid.  Without any
further process modification, undesirable iron precipitates
will be formed, remain with the solids during filtration and

be lost in the leached coal.  This fact is illustrated by
Figures 46 and 47, which show that a mixed ferric sulfate
and ferric hydroxide product will form in the reactor
effluent.  In this process the relationship between ferric
hydroxide formation and the oxidation reaction is quite
sensitive because acid that prevents precipitation is being
removed as fast as ferric ions that promote precipitation
are being formed.  The sensitivity of this relation is
reduced by the effect of leaching, but the point is clear
that excess use of oxygen means lower efficiency of oxygen/
mole FeS2 leached because of oxygen excess, system depletion
of acid, and lower efficiency of oxygen/mole leached due to
ferric ion losses.  Also the excess ferric material that
will be present in the reactor effluent will mean possible
contamination of the product coal with ferric ion solids.
This last problem could be reduced by installing the pre-
viously mentioned acid make-up line to'the reactor effluent.
The simulated effect of this addition is shown in Figures 44a
and 44b.  Without the improvements, 94-95% of the pyrite is
removed.  With the suggested improvements where make-up acid
and 9-10 moles/hour of additional oxygen are required, the
amount of pyrite removed averages 95.6%.

This disappointingly small improvement in the product is
misleading because the percent pyrite removed is expressed
as a mole percentage (100 x moles of pyrite in process
effluent/moles of pyrite in process influent).  If this
reduction in the amount of pyrite were expressed as a
percent reduction in residence time in a reactor, it would
be more meaningful, as residence time can be tied to equip-
ment size and capital cost.  By taking a closer look at the
leach rate equation, an approximate expression can be
developed to make the point clear.

where     KT = reaction rate constant
           LI
          W  = pyrite/coal weight ratio
          Y  = ferric to total iron ratio
If Y is held constant  (not true, but for the purpose of this
illustration this assumption can be made) and the expression
is integrated from f  to f., then
where     f  = reactor influent weight ratio, pyrite/coal
          f.  = reactor effluent weight ratio, pyrite/coal
          t  = time in reactor

If t is the time to reduce the pyrite content from 100% to
5% of the influent amount and t1 is the time required to
reduce the pyrite content from 100% to 4.4%, then the
percent increase in residence time required is approximately
100((t'-t)/t).

This percent increase in residence time can be interpreted in
another way:  If the residence time in the reactor is held
constant and the product is improved by increasing the pyrite
removal from 95.0 to 95.6%, then 100((t'/t)-l) is the per-
centage of residence time saved by regenerating ferric iron
in the mixer.  Examples are given on the next page and in
Section 10.8.4.

These estimates are conservative since Y was held
constant.  The value of Y will be higher when there
is regeneration in the mixer.  On a weight ratio basis
the percentage of product improvement was 14-27% which
is in good agreement with this approximate analysis.

 pyrite removal for the whole process compared to no regen-
 eration in the Mixer and overall pyrite removal of 95.0%
 for Case 1 and 94.5% for Case 2  (Calculations are given in
 Section 10.8.4).
7.3.2     Leaching Rate Constant Variation
One of the process parameters that the quality of the
product coal is particularly sensitive to is the leaching
rate constant.  This parameter is generally thought of as
constant at a particular temperature, but there are sev-
eral ways in which it will vary.

                                                          (24)
In other independent studies of pyrite leaching from coal,
it has been shown that the leaching rate varies for different
coals and that the rate is even different for stoichiometri-
cally similar but structurally different pyrites in the
same coal.
                       -216-

-------
Another source of variations in KT will occur because of
                                 LI
feed coal mesh size variations.  For instance, it may be
found that a larger feed size must be used because the
hydrophobicity of -100 mesh coal prevents it from forming
a slurry in the mixer.

In heterogeneous rate studies the specific rate constant
                              ^ I
usually has a dimension  (Area)  .  However, because of the
obvious difficulties that would arise in estimating the
surface area of pyrite, TRW expressed the leaching rate
constant for -100 mesh coal.  Therefore, the actual rate
is constant.

     K' = KT/A                                           (15)
      LI    LI

Where A = surface area of pyrite in the coal.

In order to obtain a rough estimate of the sensitivity of
the process to a change of feed size from -100 mesh to -48
mesh a simulation was run.  A particle size increase of
about two would mean an area reduction of about four.  A
rate constant reduction of four is probably conservative
as there will be fewer fines and therefore more pyrite
occluded within the coal.  Figure 48 shows the molar flow
rate of pyrite from the reactors under different operating
conditions.  Curve #1 shows the results for the -48 mesh
coal and, for the purpose of comparison, curve #2 shows
the results for the -100 mesh coal.  One can see that when.
processing -48 mesh coal additional process modifications
will have to be made in order to obtain a product with a
pyritic sulfur level similar to that obtained with -100
mesh coal.

Assuming that the rate limiting step in the reaction does
not change with increased temperatures and pressures and
that equipment modifications could be made/ several simu-
lations were made to see what type of conditions would be
needed to obtain an acceptable product.  Actions that were
taken were intended to enhance the leaching rate.  In the
first run ferric ions were regenerated in the mixer and
the pressure over the reactors was increased to 120 psia.
This result is shown as curve #4.  This action does not
improve the results because the increased regeneration
depletes the system of acid.  An acid make-up stream flowing
to the reactor effluent was included.  This improved the
product coal but not sufficiently  (curve #3).  Curves #5
and #7 show the same effects as seen in #4 and #3 with the
average temperature in the reactors increased to 170°C.
This action increases the value of the leach and regenera-
tion rate constant, but the buoyancy pressure increases
rapidly with temperature, reducing the partial pressure of
oxygen.  One final run  (#6) was made where the temperature and
pressure were increased to 200°C and 250 psia.  Under these
conditions, the product coal was acceptable.  Yet, it must
be remembered that the process was designed for 80 psia and
128-160°C operation.  Further, because of the limited range
of the temperature data, one does not know what step is rate
determining and extrapolation is no more than hypothetical.
Yet, even with these assumptions it is clear that sizable
changes in design conditions and equipment may be necessary
in order to compensate for any reductions in the leach rate
caused by larger feed size, different pyrite level, etc.
7.3.3     General Discussion
Discussion in the previous sections was centered around
                      -219-

-------
three general areas of chemistry and their effect on the
process.  In Section 7.2.3 the impact of solution concen-
tration control on the operating efficiency and the quality
of the product coal was discussed.  In Section 7.3.1 the
effect of increasing the amount of regeneration was touched
upon, and in Section 7.3.2 the leaching rate and regenera-
tion rate were covered.  The knowledge obtained by looking
at these areas will now be used as input for making minor
changes, for selecting startup conditions, and for making
operating changes when process variations occur.  This
discussion will by no means exhaust all the possible
changes or conceivable condition variations, but it will
show that the use of simulation can provide sufficient
insight into the process so that reasonable action can
be taken.
7.3.3.1   Variation of Pyrite Feed to the Process - The
assay of pyrite in coal has been assumed to be fixed at
135-136 Ib-moles per hour.  It was of interest here to see
how the process would handle variations in the feed and
what changes might be made to accommodate these variations
in the best manner possible.  The pyrite assay was made to
vary in two ways.  In one simulation the amounts of pyrite
in the feed were drawn randomly from a normal distribution
having a mean value of 135.87 and a standard deviation of
25.  This large standard deviation was selected in order to
see how the process would be affected by large perturbations,
Figures 49a and 49b show the influent and effluent pyrite
flow rates.  While the variations shown in Figure 49a occur
every hour, in the actual simulation the variations
occurred every ten minutes.  The difference is simply
                       -220-

-------
because step size for integration was made on a ten minute
basis and output printed only on an hourly basis.  Figure
49b shows that even with the large fluctuations the process
removes at least 92 percent of the pyrite.  Recall from
Figure 44a that ferric ion regeneration in the mixer
worked to dampen the pyrite flow fluctuation.  If large
fluctuations are encountered, mixer ferric regeneration
might be considered as a way for maintaining steady pyrite
to the reactors.

Another approach to pyrite assay variation is to make
step variatons that persist for a period of time.  This
method is very satisfactory for determining what accommoda-
tions are needed to meet with the change.

One such situation that is of interest is the determination
of the plant modifications that could be made when the
pyrite assay in the feed is lower.  In the situation simu-
lated the assay was reduced by 50 percent.  Figure 50 shows
the amount of improvement gained in the product for this
reduction in the pyrite feed.  This figure further exem-
plifies what is stated in Equation (9), Section 7.3.1.  The
amount of pyrite in the clean coal is quite insensitive to
the influent amount when residence time/ t, as well as KT
                                                        LJ
and Y are held constant.  However, there is some improvement
in the product beyond specification.   Some changes will be
considered that may reduce either operating or capital costs
at the expense of bringing the pyrite effluent level up.  No
changes in process layout were considered, as they would pre-
clude any easy economic extrapolations from the existing
design.
                      -222-

-------
Two simulations were made where there were five and seven
reactors.  The effluent reactor streams from these simu-
lations are also shown in Figure 50.  Another simulation
was made where the mesh size was reduced to -48 mesh, and
this is also shown in Figure 50.  As should be expected,
none of these simplifications produced an acceptable product
because feed concentration is not as important in the ki-
netic model as is the residence time or the leaching rate
constant.  With further modifications such as increased
reactor height, higher reactor temperature, higher reactor
pressure, ferric ion regeneration, etc, these new configu-
rations may be feasible, but they will not be considered
here.  The main point to be gained from this discussion is
that no significant cost savings will be realized  (other
than reduced oxygen costs) by using a feed coal that has
considerably lower amounts of pyrite.  Then it follows that
increases in the amount of pyrite present will mean only
minor adjustments in order to meet product quality specifi-
cations.  Simulation results confirm this premise.  In a
simulation the process was run for 20 hours at 135.87 moles
of pyrite/hour.  At 20 hours the pyrite feed rate was in-
creased to 140 moles/ hour and then increased again to 145
moles/hour at 30 hours.  The pyrite effluent flow rate is
shown in Figure 51.  Clearly some adjustment will have to be
made to improve the product by a small amount.   (This is
not as much as Figure 51 indicates because the initial Fe
amount was only 100 moles.  If the initial condition amount
were higher, this pyrite level would be even lower.  See
next Section).  Past discussion would suggest regeneration
in the mixer as a logical adjustment choice.

7.3.3.2   Modification of Start-up Conditions - In all
simulations discussed the fractional amount of each, com-
ponent at startup was proportional to the amounts used in
the design of the plant.  It is of importance to know which
components must be present at startup so that steady state
with an acceptable pyrite level is rapidly attained.  It
is obvious that some components must be present in signif-
icant quantities.  Acid must be present to keep ferric ions
in solution and to perpetuate the regeneration of ferric
ions.  The total amount of iron in solution must be kept at
a reasonable level so that there is enough available to do
the leaching.  Several variations were simulated to see
how long it took for the system to converge.  In one set
of simulations the amount of ferric ion present in the
mixer at startup was varied.  The curves are shown in Figure
52.  Another simulation was done where the liquid to solids
ratio was increased considerably.  These results are also
shown in Figure 52.  From these simulations it is clear
that the amount of iron in the 3+ state present at startup
should be at the plant design level or higher.  Otherwise
the product will not be acceptable until after the process
has been running for a considerable length of time.  A
period of increased 02 to the reactors would improve the
initial product if the iron  (III) were low.  Note that a
high liquid to solids ratio means a very poor product coal
will be produced.  Perhaps initial solids recirculation
would be the best way to bring the mixer up to volume.

7.4  SUMMARY

This study satisfies two objectives:  The coal desulfur-
ization chemistry as it relates to the process has been
studied and recommendations made concerning additional
data needs and process modifications.  Also the simulation
model provides a means for studying the process sensitivity
to condition and equipment variations.  Its use will provide
quick answers at a minimal expense to the user.  Also, it
can be expanded in more detail once the needed data are
obtained.  At that point it can be coordinated with an
economic evaluation program so that any questions can be
answered with reasonable accuracy from-both a physical-
chemical and economic point of view.

7.5  CONCLUSIONS

A.  The proposed process under the assumptions and condi-
tions of design shows no excessive buildup or depletion
of necessary components.

B.  More laboratory data are needed in the following areas:
     (1)  Density and heat capacity data are needed to allow
     better estimates for residence times, vessel volumes,
     evaporation rates, and heat exchange calculations.

     (2)  The conditions of precipitate formation need to
     be defined.  The acidic-basic ferric sulfate system
     is well defined in the temperature range of interest,
     but the ferric hydroxide and ferrous sulfate systems
     are not defined in the temperature and ionic strength
     ranges of interest.  Precipitation of ferric hydroxide
     can mean contamination of clean coal and reduced effi-
     ciency of oxygen usage.  Iron sulfate removal energy
     costs are directly related to ferrous sulfate solu-
     bility, so the importance of this solubility data is
     obvious.

     (3)  Experimentation should be done to determine
     whether sulfur is a product of a continuous pyrite
     leaching operation.

     (4)  The leaching reaction should be studied at higher
     temperatures to determine whether increased temperature
     causes any change in the rate controlling step.

     (5)  Experimentation should be done to determine the
     correct stoichiometric coefficient for the ferric ion
                       -228-

     involvement in the leach reaction.  There is some
     indication that the oxygen requirement may be 50%
     higher than the design indicates.

C.  The iron sulfates removal operation is favorably located.
Ferrous sulfates can be removed at this point with a mini-
mum amount of water evaporation.  Also, the potential for
ferric hydroxide or sulfate precipitation is lowest at this
location.

D.  The oxygen usage efficiency would be increased by in-
stalling a surge tank for additional leaching between the
mixer effluent and the point where stream #16 is taken from
stream #5.  The capital costs should be balanced against
lower oxygen cost.

E.  A pH controlled acid make-up stream into the reactor
effluent is needed to keep ferric precipitates from forming,
adhering to the coal during filtration and leaving the
process with the clean coal.

F.  Regeneration of ferric ions in the mixer does improve
the leach operation.  The improvement studied used 9-10
moles/hour of additional oxygen.  This regeneration in the
mixer rapidly depleted the system of acid, so an acid make-
up stream would be required.  Regeneration in the mixer
would also mean low oxygen efficiency as more ferric mate-
rial would be removed in the iron sulfate removal stage.
Part of the efficiency could be regained if the surge or
holdup vessel mentioned in  (D) above was used.

G.  Reduction in the leach rate because of differences in
pyrite structure, mesh size of the coal, etc. will lead to
serious operating problems.  Simulations for a hypothetical
                       -229-

-------
-48 mesh coal indicate that either much higher temperatures
and pressures or longer residence times will be required in
the reactors.  Preliminary reduction of the amount of pyrite
in the coal will not solve the problem.  A simulation of
-48 mesh coal with half the pyrite present does not meet
the specifications.  The variable that could improve this
situation considerably is the level of pyritic sulfur in
the product.  Small increases in this acceptable level
can mean decreased reaction time.

H.  The process responds well to large random variations in
the feed.  The pyrite removal remains within an acceptable
range with only small and infrequent time periods in which
oxygen is wasted.

I.  Reductions in the pyrite feed assay which are constant
for considerable periods of time will reduce the efficiency
of the oxygen usage unless its flow rate is controlled by
some type of on-stream pyrite feed analyzer.

J.  A large reduction in the amount of pyrite in the coal
fed to the system has only a small effect on the quality
of the product coal.  Consequently, it does not follow
that a sizable reduction of the pyrite feed assay will
mean a considerable plant cost reduction.  There will be
an operating cost savings through reduced oxygen costs,
however.

K.  As the product coal quality is insensitive to reductions
in pyrite feed assay, it is also insensitive to increases
in assay.  This means that this process can handle larger
amounts of pyrite by merely increasing the oxygen feed
                       -230-

proportionately.  If additional 02 is required, its addi-
tion in the mixer will provide a longer leach residence
time.

L.  At startup, care must be taken to ensure that at least
minimum acid, Fe   and liquid/solid levels are maintained.
Otherwise a large amount of the initial product will not
be acceptable.

10.4 REACTION SYSTEMS

The reactor system was given thorough mathematical modeling
which was discussed in Section 4.2.
10.4.1       Computer Programs for Reaction Systems
Computer programs for the various reactor configurations
are listed in the following pages.

Reaction system calculations were done on an EAI #640 dig-
ital computer with a 16,000 word memory and eight sense
switches.  The programs were written in-standard Fortran
IV computer language except for the use of logical vari-
able SENSW.  In these programs SENSW(N) is interpreted by
the compiler to check the Nth sense switch for a true or
false condition.  To use these programs with other machines
the variable SENSW(N) will have to be assigned a true or
false value before it can be used in a logical expression.

Proper units for data input are specified on comment cards
in the program.  Concentrations used in calculating chemical
reaction rates are in units of Ib moles/cu ft.  Molecular
weight and density data were taken from "The Handbook of
                       (25)
Chemistry and Physics"     with the exception of the molec-
ular weight of coal.  A value of 13 was used for the molec-
ular weight of pyrite-free coal to maintain consistency
between this report and the TRW report

In the batch reactor and the plug flow reactor programs
(programs A and C) the reaction rate equations in Section
4.2.1 are integrated directly with the fourth order Runge-.
Kutta integration subroutine.  For well mixed tanks or well
                         -385-

-------
mixed sections in series  (Program B) the steady state
equation
         input + generation by reaction = output
is solved by an iterative method.

In Section 4.2 four reactor systems are summarized.  Pro-
grams A-C were employed for these evaluations as follows:

                 -with External Regeneration

10.4.2    Computer Printout for Reaction Systems
The data used for Summary Tables 5-8 in Section 4.2.4 are
presented here in full.  In addition, the printouts from a
number of other runs are included to illustrate the effects
of conditions somewhat different from those summarized in
the main text.  These other runs were used to help determine
the ranges of interest of system variables such as reactor
size, feed temperature and liquid to solids ratio.  For
continuous reactors with external regeneration a number of
runs are presented to show the effect of regeneration
temperature on regeneration reactor volume.

For continuous reactors in parallel the alternative runs
given are printouts from a series of early exploratory runs
wherein the ratio of liquid to coal solids and the concen-
tration of iron ion were changed, and the mixer and reactor
volumes were adjusted correspondingly to accommodate the new
solution conditions.  The residence times, reactor temperature,
% conversion of FeS2 in the reactor, and the amounts of iron
sulfate solution, acid, and water removed or added were
altered, partially by cut-and-try methods, to get a meaning-
ful output.  The program used for these alternative runs
was an early version arranged so that all of the oxygen was
introduced in the mixer but did not participate in the
reactions until the slurry reached the reactors.  Also,
conditions had not been optimized to give a 102°C mixer
outlet temperature.

Calculation of Sulfur Forms in the Product Coal
Utilizing the detail from the foregoing section and the
sulfur forms analyses from Table 2 in Section 4.1.1, the
residual sulfur in the product coal, Stream #53/ may be

calculated as follows:
Basis:  One hour of operation for one train  (tons/hr column
        in Section 10.5.2, Stream #53).
  Total weight less moisture,
      (118.6806 - 4.5559  = 114.1247 or 114.1 T

-------
Note that 0.67% organic sulfur in the feed coal containing
6.7% FeS2 becomes 0.714% in the product coal because the
denominator in the fraction, S/coal, has been reduced by
the amount of FeS2 converted less other residual compounds
remaining.  Similarly, when 95% of the initial 6.7%
is removed the residual FeS- is more than 0.05 x 6.7 or
0.335%.  Excluding other residuals it would be,
          0.05 x 6.7 x TOO   0.335 X 100   n -jc^oa

10.7.3    Chemical Leaching Added to an Existing Coal
          Preparation Plant ^  '
One interesting alternative is the incorporation of chemical
leaching in conjunction with inorganic sulfur and ash re-
moval by conventional coal washing equipment.  This write-
up describes how such conventional coal preparation might
be used and provides a hypothetical basis from which an
optimized assembly of processes can be structured.

A number of coal companies produce a primary product of low
ash and low sulfur values in their preparation plants.  The
premium product may be sold as metallurgical grade coal, or
it may be blended with other grades for various uses.  The
heavier fraction is reprocessed, using a higher specific
gravity for the separation and giving a lower quality prod-
uct, but one that can be used in some areas or recombined
with primary product for use as a steam coal.

A block flowsheet is given in Figure 53, showing in general
terms primary and secondary washing where just the best 20%
of the float coal and the worst 7% of refuse are separated,
while the bulk of the coal, as middlings, is forwarded to the
chemical leaching process for upgrading.  The TPH figures
are representative only.  The proportions would vary in
accordance with the particular coal, the equipment used,
the desired product specifications, and the economics.  The
coal leaving the leach process has the initial pyritic sul-
fur content reduced by 90 to 95% as needed to meet product
specifications.-  This is blended with the previously sepa-
rated float coal for a greater overall yield than could be
obtained by washing alone.

The coarse preparation includes a picking table and
scalper grizzlies on 8-inch centers to remove large pieces
of rock or large pieces of coal which are broken with a
sledge hammer and then added to the bulk of the coal being
conveyed to coarse screens and a breaker.  This would
ordinarily be done at mine mouth.

The coarse screens make a three-way split:  Undersize,
below 3/8 in., is advanced to the secondary preparation.
Oversize is crushed to 1 1/2 in. topsize, and this is combined
with the 1 1/2 in. x 3/8 in. midscreen fraction and is
conveyed to the primary preparation step.

In the primary preparation a light fraction, e.g. <1.25
specific gravity, is separated.  Some product is withdrawn
from this, and the remaining float material is ground and
moved to the light end of the secondary preparation circuit.
A very heavy sink fraction, e.g. >2.4 specific gravity,
is removed and discarded and the somewhat lighter fraction
of this high density material is ground and fed to the
heavy end of the secondary preparation.

Data are given in Table 29 and Figure 54 for Lower
Kittanning coal float-sink tests.  The specific gravities
and sizes discussed here are taken from these data.  These
parameters are adjusted to fit the data for the coal being
handled.

The equipment in the primary preparation section is
assembled from an assortment of jigs, cones and cyclones
and is operated with water, a heavy liquid, or a suspen-
sion to produce the desired light skimming and discharge
of stone for the relatively coarse material.

Rough estimate of coal preparation,
based on 680 TPH:

1 Separate 7% (50 TPH) for fuel coal.
Forward remainder to light end of (2)
2Assume 13% after the above 7% is
gone. Separate 6% (40 TPH). For-
ward 7% to light end of next grind.
3Assume about 7% left <1.27 after
9O TPH are removed. Separate 6%
(4O TPH)
4Assume 7% is discarded. This could
be reprocessed by the Bureau of
Mines two-stage froth flotation
method and the coal fraction for-
warded to the leach step.

The secondary preparation also uses cones, cyclones, and
heavy media on the smaller sized material.  Additionally,
concentrating tables are used to good advantage on the plus
28 mesh fine coal and froth flotation on the under 28 mesh
fines.  A complete study is needed to determine proper equip-
ment to fae installed for coals in a given region.  A typical
arrangement of circuits involves crushing, screening and
skimming.  Part of the undersize from each crushing is
advanced to the next circuit and part of the lightest and
heaviest material is removed for blending  (in the case of
float coal) or discard  (heavy), while the remainder of the
light ends and heavy ends receives additional processing.
The bulk of the crushed material at each step moves to the
next size reduction.  Some of the relatively dry, coarse
float coal with just above 1.25 specific gravity is pulver-
ized in this section and added to the dewatered coal to
increase the average dryness.

The washed, pulverized middlings from the secondary prep-
aration could be fed to the mixing tank for processing
through the leach system.  Meeting fuel coal needs from the
float coal would increase the usable product from the proc-
ess.  The leach process product could be blended in with
the remaining float coal to increase the overall plant
output.  Where a utility is located adjacent to the prep-
aration plant, waste heat or steam and cooling tower service
could be obtained from the power generating facility.

The leach plant could also share with the preparation plant
or utility and possibly not be debited for the following:
site preparation; general administrative, shops, warehouse,
service and yard facilities; coal handling facilities and

personnel.  The leached, dewatered product could be blended
with the ground dewatered, float coal, and the installation
could be adapted such that no further drying nor compaction
was required.  Existing storage silos and conveyors could
be used.

Case 3 CP
Discussion — This case illustrates a method of assessing
the value of being able to apply chemical desulfurization to
middlings coal from a gravity separation process.  With
chemical desulfurization, a hypothetical 680 TPH preparation
plant could be operated as in Figure 53, Section 10.7.3 to
obtain high quality float coal with sequential grinding and
separating yielding 500 TPH of middlings to the chemical
process. Without chemical desulfurization, the tendency would
be to grind the coal more fine to maximize the float coal and
minimize the refuse and poor middlings quality that would have
to be discarded because they could not meet present fuel
source performance standards for air quality in the vicinity
of the coal combustion plant.

The disposition of the coal is given below for 680 TPH, 7920
hr/yr operation for two such cases:
Sp. Gr. Control            <1.27 Float        <1.35 Float

An estimate of costs for coal receiving and complete

A meaningful estimate of the value of reprocessing the
middlings in a chemical desulfurization plant would require
a much more exhaustive study of plant data and- economics for
a well defined preparation plant, various alternative methods
of operating a complete facility, waste disposal methods and
accounting practices for a particular organization.  The
following assumptions and calculations indicate the impact of
one interpretation of the value to the Chemical Processing
plant.

     a.   Existing Plant, Costs
          1)  Preparation plant and high ash residue disposal
              costs spread to the float coal:
                  (5200 + 160) ? 3374 = $1.60/T
                         -572-

-------
     b.   Chemical Processing, Credits
          1)  Credit from existing plant for
              avoiding cost of middlings disposal:       640
          2)  Middlings are available to Chemical
              Processing at nil cost thus saving
              the raw material cost of $8.80/T
                 8.80 x 1616 = $14,220 M/yr           14,220
                    TOTAL Operating Cost Reduction    14,860

Effect on Chemical Processing Regions                -$4.50/T
  14860 f 3300 = 4.50

     Refuse disposal might cost less.  The comparable coal
     value is indeterminate — alternative R.O.M. coal
     grades would have a lower value but receiving and grind-
     ing costs would need to be added.  Tax and accounting
     practices would need to be considered.  Use a conservative
     credit of $2.00/T.
          Case 2 CP, Chemical Processing              $6.85/T
          Less the above credits                      -2.00
          Case 3 CP, Chemical Processing              $4.85/T

Calculations — The costs related to the existing coal
handling facilities were approximated.  Units are generally
$M for capital, $M/yr for costs and $/T for unit costs.

Example costs expended to separate float coal;

a.   Scale-up Factor
     Base Case, 121.65 TPH/train x 4 x 24 x 330 = 3854M TPY
     This Case, 680 TPH x 7920 hrs/yr           = 5385M TPY
          680 TPH is 5385/3854 = 1.4 x Base Case

10.8 CONTINUOUS SIMULATION MODELING PROGRAM (CSMP)
10.8.1    CSMP Listing
This program was developed for the purpose of looking at
the process chemistry using a transient state material
balance as a basis for chemical calculations.  The reaction
kinetics configurations are those presented in Section 4.2.

The CSMP program was run on an IBM 370/155 computer.  CSMP
is a program package that was developed by IBM for the
simulation of continuous systems.

The minimum machine configuration for CSMP is a System/360
Model 40G CPU(2040) with Floating Point Arithmetic  (#4427).
The minimum partition or region size is 102K when using
FORTRAN IV  (G) Compiler and Linkage Editor Level F  (88K).
One IBM 2311 Disk Storage Drive or equivalent (in addition
to the operating system residence DSPD) is required to install
CSMP, but this need not be dedicated disk storage.  While not
necessary for execution, one 2400 series tape drive is
required for system installation.

The partition or region size required for execution of CSMP,
is determined by the largest of the four phases:  translator,
FORTRAN IV compiler, linkage editor and execution.

10.8.2    Conditions of Iron Precipitate Formation
In the coal desulfurization process there are three types
of precipitate that can form:   (1) ferrous sulfate,  (2) ferric
hydroxide/ and (3) a solid solution of acidic to basic ferric
sulfate.  The purpose of this section is to discuss the
conditions where these precipitates will form and indicate
where additional data will be required to better define
the process.

(1)  Ferrous Sulfate
                          (29)
Sources in the literature     report the solubility of
ferrous sulfate in terms of grams of H^SO. and grams of
FeSO, per fixed volume of solution.  In.order to interpolate
and possibly extrapolate to different conditions, a relation-
ship had to be developed to fit these data.  The general form
selected was

     K-L =  [Fe2+] [S042~]                            (16)

Since many of the streams are quite acidic an additional
relation was included:
           [HSO. ".]
      2    [H+][S042~]                              (17)

The value  of the equilibrium constant, K~, is known  to be
   1
 (10   ).  Therefore, for pH values  above pH  1.9,  form
 (16) was used.  Below pH 1.9  [Fe2+][HSO4~]/IH+]  was used  as
a relative indicator of ferrous sulfate solubility.   Plots
of K, and K,/K2 did not remain constant across the range
                       -595-

-------
of solubility data.  If forms  (16) and  (17) are correct for
ferrous sulfate precipitation, then the variability must be
due to variations of activity coefficients.  Since activity
coefficients vary in magnitude with ionic strength, it was
decided to make ionic strength corrections.  However, the
determination of mean activity coefficients is quite dif-
ficult and it would require extensive experimentation.
A less accurate but reasonable alternative that was used
relates the constants directly to ionic strength using
polynomial regression.  CSMP was then used to calculate
stream and vessel ionic strengths.  These ionic strengths
were used as input to determine the constants K, and K,/K2.
The results were realistic when the ionic strengths calculated
by the CSMP were within the range of the existing solubility
data; however, the majority of desulfurization ionic strengths
were beyond the range of the data.  Extrapolation beyond
the data yielded unrealistic results so the approach was
                                                  2+     2-
limited in its usefulness.  However, the terms [Fe  ][SO.  ]
       2+      -    +
and  [Fe  ][HSO. ]/[H ] are useful as relative indicators of
ferrous sulfate solubility.  More data will definitely
have to be generated to define the ferrous sulfate system.

(2)  Ferric Hydroxide
The precipitate ferric hydroxide or ferric oxyhydroxide has
a solubility product constant that varies with time and
conditions of precipitation.  Actually, many of the re-
ported values are "apparent" solubility product constants
rather than a solubility product constant in the thermody-
namic sense.  The solubility product relation is
                       -596-

-------
     K = Kw3  [Fe3+] [H+]~3                               (18)

where     Kw =  [H+][OH~] = 1 x 10~14

                                       (22)              —17
Values of K reported in the literaturev   ' vary from 10
     —44                             —17
to 10    at 25°C.   In this process 10    will probably  be
most realistic because it corresponds to a value reported
                           2+
where rapid oxidation of Fe   occurs.  There are several
other factors that must be considered in arriving at a  K
for the coal desulfurization process:   (1) K will vary
with ionic strength in an inverse manner.   (2) K is in-
versely proportional to temperature.   (3) Laboratory values
of K may not predict process conditions' if the forward  rate
is slow.  Further experimental data will be required to
fill these gaps.  Yet, the CSMP calculated quantity  (18)
will provide a relative indication of conditions in the
process.
 (3)  Acidic-Basic Ferric Sulfate
The iron  (III)-sulfate-water system has been well defined
                                                    (21)
across the region of interest by Posnjak and Merwin
who experimentally developed a ternary diagram  for the
Fe20_-S0^-H20 system.  Theoretically, there should be
little influence of the ferrous sulfate system  on the
structure of this ternary diagram.  This appears to be
true as indicated by a plot of FeO-Fe_O_-SO-,-H90 data from
        (29)
Seidell     on a ternary diagram  (Figure 55).   The solu-
bility limits plotted on this curve agree with  those of
Figure 46.  This form of diagram was used in conjunction
with CSMP molar amounts in an effort to determine where
ferric sulfates would form in the process.

  -14       —7
10    and 10   respectively.  Hence  the  stable  regions for
 2-    -
S  , HS  and H2S can easily be determined.

  Species        Stable pH Range

     S2~            >14     (at pH=14,tHS~] = [S2"])
    HS                7-14
      HO               y/ 1
     «o               v /

Therefore, Equations  (24),  (28), and  (29)  can be neglected
in a study of pyrite  oxidation  in acid  solutions.

                19                         -
Also, KHSQ- = 10    ,  which  implies that HS04  is the
stable species below  pH 1.9.  The equations listed above
can be used in conjunction  with free energy data to de-
termine the regions of stability for aqueous solutions.

From fundamental thermodynamics

     AFr = AFr° + RTlnQ                                 (30)

where    AFr s? free-energy  change of the reaction  .

         AFr° = standard free energy for the reaction

          Q = reaction quotient

          T = temperature,  °K

          R = gas constant, 0.001987 kcal/°k
                         -60O-

and
     AF° = nE°f                                         (31)
       r = nEhf                                         (32)
where     n = number of electrons transferred
          f = Faraday constant, 23.06
          E  = standard reaction voltage at unit
               activity  (reference: hydrogen)
          E,  = total emf.
Then
     E
Equation  (33) is the relation used to determine regions
where certain species predominate in aqueous solutions.
An example of how the actual equation is developed will be
shown using Equation  (27).  The first step involves the
determination of the standard free energy change for the
reaction
     AFr° = AFS042- + 10AFH+ + 8AFe- - AFH2S " 4AFH20

          = -177.34 +0+0 -(-6.54)-4(-56.69)
          = 55.96
Then
       E° = 0.303
and
       E
        h = 0.303 +    InQ
          = 0.303 +   'a   logQ
                       -6O1-

-------
Q =
             [SO,2 .].[H+]10
            - 2 -
                [H2S]
Then                            [so.2-]
     E. = 0.303 +  0.00738  log  (	)  -  0.0738  pH
                                 [H2S]
An E, -pH curve for this  equation  is  drawn for the condition
     2-
[SO.  ] =  [H^S] which reduces  the equation to:

     E  = 0.303 - 0.0738 pH
Since equation  (27) shows the transition  from the  -2  to
+6 valence state, it will not be  useful to  isolate the
stable region of sulfur.  The equations that  can be used
to isolate the stable sulfur region  are  (23) ,  (25) , and
(26).  Equation  (19) can be neglected because it has  no
E,-pH dependency.  Equations  (21)  and  (22)  were already
used to isolate regions of sulfide ion stability.   Finally,
equation  (20) has an E,  of approximately  -0.44 in  all
regions of interest.  The E,  equations are  plotted in
Figure 56.  Superimposed on the E, lines  are  regions  of
process operation when ferric ions are regenerated in the
mixer.

10.8.4    Calculations of the Effect of Ferric Ion
            Regeneration in the Mixer
As indicated in Section 7.3.1 the small improvement in
overall product quality resulting from adding oxygen and
make-up acid to the Mixer becomes more significant when
viewed from the standpoint of residence time.  The
relationship developed was

          f. = reactor effluent weight ratio, pyrite/coal
          t  = time in reactor
The "reactor" system here is intended to be the entire Mixer-
Reactor system of the design.
Assume:
     (1)  Influent weight of coal/hour = 17,461 Ib mol/hr
     (2)  Influent weight of pyrite/hour = 135.87 Ib mol/hr
     (3)  KTY2 =  (31.81) (0.7)2 = 15.59, held constant

where     119.9 = molecular weight of pyrite
           13.0 = molecular weight of coal
Examine three different levels of ft:  5.0%, 4.4% and 5.5% of
the initial level.

Then f   = 0.050 x 0.0718 = 0.00359 for 5.0%
     f ,  = 0.044 x 0.0718 = 0.00315 for 4.4%
     f „  = 0.055 x 0.0718 = 0.00395 for 5.5%
