16. Abstracts patlofrl?! coals studied, only 21 are suitable for the reduction of sulfur by
existing benefication methods. Sulfur in about 55 coals could be reduced to either less
than 1.0% at a sacrifice in the yield (to less than 75%), or at a sacrifice of sulfur
level, (i.e., 1.0% to 1.5% Instead of less than 1.0%). At the present price levels for
low sulfur coal, no coal company would be interested in making an investment to wash coa]
in this category unless a sufficient premium is given for low sulfur coal to compensate
for the low yields of washed coal. Enforcement of more stringent anti-air pollution
requirement would create a greater demand for low sulfur coals, which would surely raise
low sulfur coal prices. Considering the capital investment and the operating costs of a
50 TPH prototype plant, offices and laboratories, the construction of a full scale commer
cial plant with a 50 TPH test circuit may be worth some consideration. From a cost stand-
point, the administrative, office and laboratory personnel as well as the laboratory cost
would be about the same for either a test plant or a commercial size plant-oMoreoซrfirป:ปi-
full scale plant with necessary test circuits would be of substantial value from both a
scientific and commercial viewpoint; the possibility of operating the plant for its full
life period would be of considerable commercial advantage.

SYNOPSIS
1 . PURPOSE
Among the various pollutants in the air, oxides of sulfur (primarily
SOg or sulfur dioxide) are the moat common pollutants injurious to
the health and detrimental to property values. Their sources are
broad, but the majority of them come from thermal power plants and
various other industries. Losses to property values alone amount
to several billion dollars annually.
With the growth of cities and industries, the air pollution menace
is increasing. It is estimated that by 1970, approximately 36
million tons of SOp are expected to be emitted into the atmosphere.
To combat the air pollution menace, Congress passed federal legis-
lation on air pollution in 1955, the Clean Air Act in 1963 and
finally the Air Quality Act in 196?. Under the Air Quality Act
57 air quality control regions have been designated on the basis
of meteorological and topographical factors.
At present considerable work is being done in the following areas
to control emission of SO,, gas into the atmosphere:
a) Removal of sulfur compounds from coal before combustion;
b) Removal of SOo from the flue gasj
c) Location of low sulfur coal reserves; and
d) Change in in-process technology.
X
To investigate removal of sulfur compounds from the coal before it
is burned, the U. S. Department of Health, Education and Welfare
has awarded a contract, No. PH-22-68-59, to The McNally Pittsburg
Manufacturing Corporation. Under this contract the following points
were to be investigated:
a) To study approximately 200 sets of coal washabllity data
from which to evaluate and classify coal suitable for
-------
The McNolly Pittsburg Mfg. Corp. Proposal No. 62521
Page
II
b) Tec-develop a scheme of ranking for these coals;
c) To develop a design for the most appropriate, conventional
type coal cleaning plant to remove sulfur compounds;
d) To develop the installed cost of the plant, and estimated
costs for the operation of the plant;
e) To develop test schedules for the evaluation of each ooal
to be processed in the plant;
f) And finally to estimate costs for the analysis of data
to be generated in the prototype plant and develop flow-
sheets for full scale plants for the coals washed in the
prototype plant.
2. ANALYSIS
Prom the washabllity data supplied by the Department of Health,
Education and Welfare, 171 coals have been analyzed and categorized
into the following six groups:
a) Raw coal having total sulfur less than 1 .0$, 1 .0% to
1 .5$ and 1 .$% to 2.0$.
b) Raw coal cleanable to less than 1.0$ total sulfur.
c) Raw coal cleanable to 1 .0$ to 1 .5$ total sulfur.
d) Raw coal oleanable to 1.5$ to 2.0$.
e) Raw coal cleanable to 2.0% to 2.5$-
f) Raw coal not cleanable to less than 2..$%.
Under group (a) there are two coals with less than 1.0$, nine coals
with between 1.0$ to 1.5$, and fifteen coals with between 1.5$ to
2.0$ total sulfur. Two coals with less than 1.0$ sulfur do not
require washing for sulfur reduction. Since coals with 1.0$ to
1 .5$ total sulfur can be utilized in most -of the states within air
pollution control limits, the nine coals with 1.0$ to 1.5$ sulfur
would normally not require treatment for sulfur reduction. If
required, seven coals out of nine can be washed to reduce the sulfur
content to less than 1.0$.
For the groups (b) to (e) only, 3/8" x 0 size raw coal with a
recovery of more than 75$ washed coal has normally been included.
If a 75$ recovery for a given coal is not obtainable at that size,
or is on the border line, it has been put into the next higher

sulfur group. Washing at 1i|M x 0 has been considered only for those
coals which fall in the sulfur group of 2.0$ to 2.5$j as otherwise
these coals will fall in the category of coal unwashable to less
than 2.5$.
In group (b) thirteen coals are cleanable to less than 1.0$ total
sulfur. Under group (c) sulfur for twenty-three coals can be reduced
to a 1.0$ to 1 .5$ sulfur level. From group (d) twenty-two coals
can be cleaned to the sulfur level of 1.5$ to 2.0$. In group (e),
the total sulfur for twenty-four coals can be reduced to 2.0$ to
2.5$. In the last group, (f), seventy-eight coals are not cleanable
to less than 2.5$ total sulfur. The sulfur present in these coals
is so finely disseminated that the reduction in the sulfur could be
effected only at a great sacrifice in yield of clean coal, making
washing uneconomical.
3. RANKING
A method has been developed for the three sizes of coal considered
to show the theoretical recovery and the total sulfur content of
clean coal from the washability data supplied. These three factors
are considered in the following manner:

For example, a ranking of 1A^ means a 1-1/2" x 0 size raw coal with
a possible yield of between 75$ to 100$ with a total sulfur of less
than 1.0$. Similarly, 2B, signifies a 3/8" x 0 size raw coal which
when washed could yield 50$ to 75$ clean coal having a total sulfur

Out of the 1?1 coals analyzed, twenty-two coals are considered
to be "good", or in the AI Series; twenty-six coals are fair
(Series A2 or B.^); twenty-nine coals are average (Series A^ or
B2 or C); and the remaining coals are poor or unwashable, due
to either low yield in clean coal or high sulfur level in the
clean coal.

lu PROTOTYPE PLAHT (SEE FLOWSHEET & PHIT LIST. PAGES X tc 3CI)
Keeping in view the complexity of washing these different coals
with widely varying waahabllity characteristics, the prototype
plant should be designed with sufficient flexibility to remove
sulfur from raw coal under a wide range of conditions. The plant
recommended would be of ฃ0 TPH capacity, and would have a coarse
coal circuit with a heavy media cycloid for cleaning the various
sizes of IV x 3/8", IV x 1UM, 3A" * 3/8", 3/k" x UjM and
3/8" x 11)11 coals; all fractions 3/8" and below would also be
treated by the fine coal circuit.
Coals which should be crushed to 3/8" x 0 or lt)M x 0 would be
washed in the fine coal circuit having available primary and
secondary McNally-Viaman Triconea, ore and coal tables, and flo-
tation cells. The pyrite recovery system would be provided with
both ore tables and a secondary McNally-Visman Tricone, since
the primary MoHally-Viaman Tricone is not only efficient in
washing fine coals at a low gravity, but the secondary Tricone1
can also be used in treating high specific gravity material at
a high cut point.
Besides the fine and coarse ooal circuits, adequate arrangements
have been made for unloading, handling, and crushing raw ooal as
well as handling of clean coal and disposal of refuse. There
will be a water clarification system to reuse the clarified
water in the washery. An 8000 ton capacity raw coal storage
facility has been provided through two 1^000 ton silos for storing
sufficient raw coal for one month's operation.
Th* McNally Pittsburg Mfg. Corp. Proposal No. 62521
Pag* V
The recommended prototype plant has been provided with alternate
circuits and equipment choices which can be run in any combination
so that it will be able to handle coals of different sizes with
widely varying washability characteristics. In the absence of
standard methods for the recovery of pyrite from the washery refuse,
alternate circuits as well as alternate equipment are provided to
determine the most suitable process for pyrite recovery from any
given coal.
Although not included in the present plant design, the installation
of a fluid bed type thermal dryer should be given consideration.
The dryer could be used to process the fine coal with a high
moisture content to provide valuable operating information. These
data could then be used to assist coal cleaning plant, dust collector
designers and operators to meet air pollution restrictions in the
supply and operation of full scale plants and equipment.
To achieve the greatest good from this project, close cooperation
from a large coal operator will be a great advantage. Taking this
into consideration, help from the Peabody Coal Company has been
arranged; they have offered the use of one of their Idle ooal
preparation plants near Terre Haute, Indiana, for this project.
Peabody Coal Company has also agreed to extend the necessary help
to direct the work and operate the plant by men experienced in the
coal preparation work.
The site is easily accessible, and all the facilities such as ground
space for additional clean coal storage, a more than adequate refuse
disposal pond, a large fresh water pond, and utility services are
available. The plant site also has adequate free space available
for a future roasting and chemical plant for processing the recovered
pyrite from the washery refuse.
5. OBJECTIVES
The object of the prototype plant is to generate information on the
reduction of sulfur for a given coal. Keeping this in view, adequate
sampling and testing arrangements have been provided to evaluate each
-------

Pa08 VI
sampling pointstwanty-sevon (27) automatic pulp and solid
samplers and two (2) manual sampling arrangements.
The purpose of the testing program is to: (1) evaluate each coal
selected for washing; (2) evaluate performance of each piece of
equipment used in the plant; (3) select the proper circuit for a
given coal; (14.) evaluate overall performances of the plant for
cost analysis; and (5) to make comprehensive plant studies includ-
ing material, ash, and sulfur balances for each coal.
The teat schedule calls for optimum adjustment for most efficient
ooeration of esch piece of equipment as well as for each separate
circuit in the plant. After the equipment and the circuits aro
sot for their beat performance in sulfur reduction, prolonged
test runs will be made uith all the sampling stations of all the
circuits in use so that a complete plant evaluation can be roado
for each coal washed.
The plant feed and final products for each coal will have complete
i'.lt:j!iat3 and nrcximato analysis to determine the burning and
slagging characteristics of tho fosd ao -jail as for tho final
pr-oduots. Ke^ulai1 chec:t3 will also be nado on the plant offlr.ont
aa well as on any pond water or streams which might be affoctod by
tho plant operation.
In the course of cleaning and testing ,various coals valuable infor-
mation, will be goiioratad on tlia rocuction of sulfur. Information
./.ill also bo produced on the par-romance of the individual pieces
of equipment, suitability of dif^erjnt circuits, and tho overall
performance of the plant. All of this infoitnatior. should bo
properly cataloged and stored for r-oady access. With this in view,

rotri-sval system has boou n'uggcatc.l. Cloyed circuit TV coiosuni-
cacion will also bs providad for confidential transmission of data
to the plant and laboratory operations.

6. CAPITAL & OPERATING COSTS
As indicated above, the recommended prototype plant has been designed
with both a fully equipped testing laboratory, an analytical labor-
atory and suitable office facilities have been provided. Operation
of this plant with extensive laboratory facilities is expected to
be expensive. The following cost analysis on the operation of the
plant and the laboratory has been done on the basis of one year
installation time, six months for start-up and three years for
actual operation. Estimated costs are:
LABORATORY
& OFFICE

TOTAL
Estimated capital investment
for equipment & installation $ 1,078,191 $ 2,.158,000 $ 3,236,191
Six months start-up costs $ 911,511;$ 253,335$ 1,164,&49
Operating costs for 3 years $ 5,430,000 $ 1,520,010 $ 6,950,010
Insurance for 4-1/2 years $ 11,540$ 44.165$ .55.725
$ 7,431,245 $ 3,975,530 $ 11,406,775
Depreciated value of the plant and laboratory equipment at the end
of 4-1/2 years has been assumed to be 10$ฃ of the capital investment,
or $323,619.
Coat "of 96,000 tons of raw coal (washed at half the rated capacity
during the start-up period and at 50 TPH for three years) is
estimated at $3,276,000; the sale price of washed coal la estimated at
$995,163.
7. POSSIBLE FUTURE PSE OF FACILITY
In view of the possible future benefits of such a flexible coal
cleaning and testing facility and especially considering the
contemplated capital investment, it is recommended that some
thought be given to the use of this facility well beyond the
length of the present program for future testing and development.
One would hope that there might be substantial side benefits and
some new developments in different phases of coal technology,

1. AIR POLLUTION LAW
In the year 195ฃ the first Federal legislation on Air Pollution
was passed, in the Eighty-Eighth Congress. It created Public Law
88-206, its object being to cause the removal of those pollutants
from the air which are hazardous to health, vegetation and property.
Again in the year 1963 another, more stringent clean air act was
passed. To implement these laws, the Federal Government, through
the efforts of the Health, Education and Welfare Department, is
moving to establish effective standards for the control of air
pollution on a nationwide basis. In view of the new legislation,
the U.S. Department of Health, Education and Welfare has been made
responsible to develop ways and means to remove sources of pollutants
either before combustion or after. Under the Air Pollution Control
Program, McNally Pittsburg has been awarded Contract No. PH-22-68-59
to investigate various high and low sulfur coals and to develop an
appropriate plant design to produce low sulfur coal by conventional
coal cleaning methods.
Subsequently, the Air Quality Act passed in 196? requires that the
Federal Government advise all state authorities on the criteria of
the effects of pollutants on the health and property. The Act also
stipulates that the state authorities are to be advised on the most
effective and economical methods-of controlling pollutants. The
National Air Pollution Control Administration, Division of HEW, has
set as their target that the Air Quality Act of 1967 will be
implemented by the summer of 1970. Responsibility of enforcement
of the program under the Act will be placed squarely on the shoulders
of the state authorities with supplemental help and guidance from
the regional office of the Department of HEW.
A total of 57 air quality control regions have now been designated
under this ambitious program. In each area regional boundaries are
drawn on the basis of meteorological and topographical factors. State
authorities are required to set up their own air quality etandards for
any portion of their territory falling within the air quality control

2. SOURCES OF AIR POLLUTION
There are many varieties of gases and materials which pollute the
air. The primary pollutants, however, are hydrocarbons, oxides of
sulfur, oxides of nitrogen, oxides of carbon and fine particles.
Their sources are also broad but the majority of them come from
internal combustion engines and various industries which are primarily
responsible for oxides of sulfur, oxides of carbon, oxides of
nitrogen, etc.
In spite of legislation on air pollution control, the Clean Air Act
and the Air Quality Act, the nation's air pollution problem is becom-
ing steadily worse. Pollutants in the air not only damage property
and endanger health, they are harmful for farm crops and many kinds
of vegetation. Losses to property values, to crops and vegetation
amount to several billion dollars annually. Apart from the monetary
losses for property, farm crops and other vegetation, there is also
a considerable hazard to health due to continuous exposure to
polluted air.
3. PRODUCTION k CONSUMPTION OF COAL IN THE UNITED STATES
Coal and fuel oil are the principal sources of oxides of sulfur.
Listed below are statistics on the production and combustion of lignite
and bituminous coal for the last four years, given in millions of
tons:

The consumption of coal (26) is expected to grow as follows:
1970 600 M Tons
1980
1990
2000
670 M Tons
890 M Tons
1200 M Tons
NOTE: Numerical number in parenthesis refers to bibliographic
reference. See Pages 76 and 77.
Electric utilities have been the largest single consumer of coal
since the late 19l).0's. With the growth of cities and industries
and a higher standard of living, consumption of electricity per
capita is increasing; consequently the consumption of coal by power
plants will continue to expand. It is estimated that by the year
2000, power plants in the country will utilize approximately 600M
Tons, or half of the above estimated 1200 M Tons, of coal per year.
The above figures also show that by 1970, 600,000,000 tons of raw
coal, having an average 3$ sulfur, will therefore burn approximately
18,000,000 tons of sulfur to release approximately 36,000,000 tons
of SO^ gas into the air. This illustrates the magnitude of air
pollution problem due to 50^ alone, not to mention the pollutants
like other hydrocarbons, nitrogen oxides, carbon dioxide, etc.
Present figures show that more than 20,000,000 tons of SOp gases
are being emitted into the atmosphere annually.
k- OCGURAHCE OF SULFUR IN COAL
Sulfur is found in raw coal in the following different forms:
Free Sulfur
Organic Sulfur
Pyritic Sulfur
Sulfate Sulfur
Occurrence of free sulfur has been reported in some coals but it is
generally disregarded because it exists in only minute quantities.
The amount of sulfate sulfur present in the coal varies considerably;
it increases rapidly with the weathering of coal due to the oxidation
of the pyrite. Pyritic sulfur occurs in coal either as pyrite or
marcasite. Organic sulfur in general occurs in coal in a finely
mixed condition and it is considered as an inherent constituent of
coal. As organic sulfur is intimately mixed with coal, it is difficult
to reduce by beneficiatlon when using conventional methods.
Pyrite occurs in coal in bands, in pockets, or as particles, fine
or coarse, mixed with the coal. Pyrite in bands or pockets or as
coarse particles is easy to separate by mechanical means. Fine pyrite
particles when intimately mixed with the coal are considered to be
-------
The McNally Pirhburg Mfg. Corp. Proposal No.
Page k
The total sulfur content of U.S. coals ranges from 0.20 to 7.0
percent on a dry basis. Pyritic sulfur ranges from lฑQj!> to 80$ of
total sulfur. Generally, organic sulfur predominates in the low
1 sulfur coals.
5. REMOVAL OF SULFUR FROM COAL
During World Wars I and II pyrite from coal was recovered in some
countries to augment their sulfur supply. Most of the pyrite
recovery plants operated successfully during the war days but
eventually closed down for economic reasons rather than for f
technical reason. At present efforts are again being made to re-
move sulfur from coal either as SO, gas or as a sulfur compound, not
due to a shortage of sulfur, but to eliminate the S02 gas one
of the major sources of air pollution.
TECHNOLOGICAL REVIEW
Currently, research towards the reduction of air pollution due
to the presence of sulfur in oil and coal are being directed along
the following lines:
(a) Removal of SO- gas after combustion;
(b) Removal of sulfur compounds from the fuel before burning;
(c) Locate fresh reserves of low sulfur coal; and

Concentration requirements could not be considered, however, since
HEW has as yet been unable to define the concentration requirement.
As a result, a most flexible coal preparation plant with several
alternate coal cleaning processes has been designed. With this
design it will have various techniques available for the recovery
of pyrite from the plant refuse.
SECTION 2
PROJECT ANALYSIS WOBK
From the washability data generated by the Commercial Testing and
Engineering Company and the U. S. Bureau of Mines, approximately
200 coals have been analyzed and categorized into six groupsi
1. Raw coal having total sulfur less than 1.0$, 1.0$ to
1.50$, and 1.50$ to 2.0$.
2. Raw coal cloanable to less than 1.0% total sulfur.
3. Raw coal oleanable to 1 .0$ to 1 .$% total sulfur.
i).. Raw coal oleanable to 1-5$ to 2.0% total sulfur.
5. Raw coal oleanable to 2.0$ to 2.5$ total sulfur.
6. Raw coal not oleanable to lesa than 2.5$ total sulfur.
A. Raw Coal With Low Sulfur Content
Table I shows a grouping of the raw coals whose total sulfur content
is less than 1.0$, 1.0$ to 1.5$, and 1.5$ to 2.0$. It oan be seen
from Table I, Page 1, that raw coal (CT-63 in Pennsylvania) has 0.71$
total sulfur. Although this sulfur content could be reduced to 0.69$
by washing at 1.90 Sp. Gr. recovering 98.6$ clean coal, it would not
be economical to do so. The 0.63$ total sulfur in the raw coal (BM-93
in Alabama) could not be reduced on washing. In these two coals, the
sulfur present is principally in organic form and whatever pyritic
sulfur present is so intimately mixed that it could not be reduced by
beneficiation. It would obviously not be worthwhile in these two
cases to attempt to reduce the already low sulfur level.
The total sulfur content of nine of the raw coals (BM-9lj. in Alabama;
CT-3, CT-14.9, BM-96 and BM-lj.9 in Pennsylvania; BM-103 in West Virginia;
and CT-58, BM-16 and CT-60 in Illinois) shown in Table I, Pages 1 and 2,
is between 1.0$ to 1 .5$. These coals can be utilized in most states
of the U.S.A. within air pollution control limits. In all of these
cases, except for BM-103 and CT-58, the sulfur content could be
reduced to less than 1.0$. The washability data on CT-58 and BM-103
show that the sulfur constituent is so intimately mixed that it
could not be reduced to less than 1 .0$, even by crushing it to
1ljM x 0. It would, therefore, only be economical to use this

CT-58 coal raw. Table I, Pages 3, k and 5, also show that fifteen
coals (BM-91 and BM-95 in West Virginia; CT-16, CT-19, CT-32, CT-28,
BM-39, BM-14; and BM-51 in Pennsylvania; CT-21 and BM-19 in West
Virginia} BM-29 and CT-lj.0 in Ohio; and HM-6? and BM-?0 in Indiana)
have a total sulfur content of between 1.5$ and 2.0$. A washability
analysis of the available data shows that sulfur in nine out of
fifteen coals (CT-16, CT-19, BM-51, CT-21, CT-1;0, BM-6?, CT-32, CT-28
and BM-39) could be reduced to less than 1 . 0$ total sulfur on washing
3/8" x 0 size coal. But the clean coal recovery of three (CT-32j
CT-28 and BM-39) of these coals is quite low, making it uneconomical
to reduce the sulfur to less than 1.0$. It would, therefore, be
advisable to wash these three coals to within a 1.0$ to 1.5$ sulfur
limit. Sulfur of four coals (BM-U4, BM-91, BM-95 and BM-19) out of
the six remaining could not be reduced to less than 1$ even on
crushing to 1UM x 0. These four coals, therefore, can be used
economically only at a 1.0$-1.5$ sulfur level. The washability
analysis indicates that the remaining two coals (BM-29 and BM-70)
could be reduced to less than 1.0$ by washing at 1l|M x 0 size; in
any case, however, crushing of raw coal to 1l)M x 0 to reduce the
sulfur must be considered carefully from an economical standpoint.
B. Raw Coal With Higher Sulfur Content
All other coals whose washability data have been supplied by HEW
are shown in Tables II, III, IV, V and VI based on the total sulfur
that could be logically attained by washing. Categorization of
coals from the washability data has been made based upon the
following:
(a) Theoretical recovery of total sulfur as indicated
by the washability data.
(b) In general, being the nearest to an average condition,
washability of 3/8" x 0 size coal has been used as a
guide more often than 1-1/2" x 0 or 1l)M x 0 sizes in
making the groups. The 1-1/2" x 0 size has been considered
when a satisfactory result is obtainable without crushing
to _j/8" x 0. The lljM x 0 size was considered only when
l!g" x 0 and 3/8" x 0 sizes did not yield satisfactory
results.
(c) Washed coal with a satisfactory recovery at an acceptable
total sulfur level has been the main consideration in
categorizing coals into different groups.
(d) In case of lov; recovery of washed coal (in the lowest
possible sulfur range), the same coal has also been in-
cluded in the next higher sulfur group yielding a higher
recovery of washed coal. To explain, coal from CT-32
(Pennsylvania) on washing at 1.30 Sp. Gr. yields only
37=3$ washed coal with 0.96$ total sulfur. Since such a
low recovery will make washing uneconomical, it was
considered in the next higher sulfur range of 1.0$-1.5$
total sulfur. In this case, the theoretical recovery of
washed coal would be 75.1$ with 1.16$ total sulfur when
washed at 1.90 Sp. Or.
(e) Similarly washed coal with total sulfur on the border line
has also been included in the next higher sulfur group.
For example, coal from CT-52 (Ohio) would theoretically
yield 68.6$ washed coal with 0.97$ total sulfur content at
1.30 Sp. Gr. Since in actual washing at 1.30 Sp. Gr., the
washed coal sulfur would likely be more than 0097$ป it was
also considered for washing at a higher Sp. Gr. of 1.14.0 to
yield theoretically 85.2$ washed coal having 1.30$ total
sulfur.
(f) In case it is not possible to attain a satisfactory yield
at an acceptable recovery, the sulfur content from IV x 0
or 3/6" x 0 size coal, llfM x 0 size has been considered;
the same coal has also been included in the next higher
sulfur group for washing at 3/8" x 0 size. To take an
example, the coal from BM-31 of Iowa State (Table II, Page2)
yields 89.2$ washed coal with 0.91$ total sulfur when
crushed to lljM x 0. When crushed to 3/8" x 0 size, the
washed coal has 1.3$ total sulfur when washed at 1.30 Sp.

Tables II to VI show raw ooala and theoretical yields of the washed
coals, total sulfur, pyritic sulfur and ash percentage from an
analysis of the Department of Health, Education and Welfare data.
g) Our study of 26 Illinois coals washability data reveals that,
in general, Illinois coals are high in sulfur. Total sulfur in
the raw coals studied varies between approximately 1.0$ to 8.0$.
The aulfur exists as either organic or pyritic in a disseminated
form, which makes reduction of aulfur impossible by current bene-
ficiation methods. Out of 26 raw ooala, three contain total sulfur
as low as 1 .0/6-1 .5$ and these would be the only raw coals within
the state which fall within the present/proposed air pollution
control limits. Prom the balance of 23 coals, four can be waahed
to & sulfur level of between 1.5$ to 2.0%, two to a sulfur level
of 2.0$ to 2.5$; for the remaining 1? coals the sulfur level
cannot be reduced to less than 2.$%.
This situation obviously poses some difficult problems for the
coal consumers, the coal operators and the air pollution control
authorities. At this stage of coal technology when most Illinois
coals cannot be reduced to a 1.5$ sulfur level by conventional
beneficiation processes it appears that there may be a difficult
economical period for coal consumers and producers during which
time most of their coal will have to be imported from other
states. This period could extend until economical methods are
developed and put into commercial use for reducing or removing
sulfur from coal, likely with an end result of converting coal
to gas and/or liquid fuels. Similar conditions, although not aa
severe, may exist in other areas of the country.

EFFECT OF CRUSHING UPON THE LIBERATION OF PYRITE
Pag. 11
The size of mineral particles and their distribution in raw
coal is fundamental to washability characteristics of a coal.
Pyrite is one of the constituenta of mineral matter present in
coal and its removal is necessary to reduce a coal's total aulfur
content. Removal of pyrite by conventional coal cleaning process
depends upon its characteristics aa it occurs in the raw coal
and the effect of cruahing upon ita liberation. The following
atudiea have been made on the effect of crushing upon the libera-
tion of pyrite for various coals crushed to three different sizes.
IV x 0, 3/8" x. 0 and 1UM x 0.
Table in Page 12 illustrates the effect of crushing upon the
liberation of pyritic aulfur from Ohio's Seam No. 6. This coal
waa cruahed to lV x 0 and 3/8" x 0. Reduction of size from lV
x 0 to 3/8" x 0 ahows the release of pyritic aulfur making it
possible to recover, theoretically, 89.78$ washed coal at 0.98$
total sulfur by washing 3/8" x 0 size coal; only 67.98$ waahed
coal could be theoretically recovered with 0.97$ total aulfur from
l*s" x 0 aize coal. Recoveries of waahed coal at different theo-
retical total sulfur levels for both l^g" x 0 and 3/8" x 0 aize
coal are ahown by the curve in Figure 1.
Figures 2 and 3 ahow other curves which illustrate the effect of
cruahing upon the liberation of pyritic sulfur (for the coals from
CT-7 and BM-58 in Ohio). Figures k and 5 have curves which show
that, while there is a considerable liberation of sulfur (pyritic)
when crushing coal (from CT-kl and CT-21). in Ohio) from lV x 0
to 3/8" x 0, there ia hardly any effect when crushing the same
coal from 3/8" x 0 to ll^M x 0. The curves for Figures 1|. and 5
serve to show that the total sulfur present In 3/8" x 0 size
coal is more or lesa inherent in nature and cannot be liberated

In the same context, Figure 6 curves show that coal (from BM-105
in Ohio) on crushing from IV x 0 to 3/8" x 0 does not liberate
an appreciable amount of sulfur; however, as the curves indicate,
the same coal when crushed to IkM x 0 does release further sulfur

STUDY OF WASHABILITY DATA
Pugt 19
Using the subject washability data, a prototype coal preparation
plant has been designed to reduce the sulfur in these various
coals, when practical to do so. This broad range of washability
data cover coals with a wide variety of characteristics. It was
therefore necessary to design a plant which would be flexible
enough to handle all types of coals, coming from the various coal
seams. To appreciate the complexity of washing problem from the
several states involved, a few typical washability data from
those supplied by HEW have been selected for the discussion out-
lined below.
The 3/8" x 0 size has been considered primarily because there are
very few coals from which the sulfur can be reduced to an accep-
table sulfur level at a satisfactory yield for the IV x 0 size.
As would be expected, in most coals a greater sulfur reduction can
be attained at lljM x 0 than at 3/8" x 0, but it would be unecono-
mical to crush coal to ll|M x 0; washing of this size coal has not
been considered unless this was the only way to achieve an accep-
table sulfur level.
Figure 7 is an illustration of a 3/8" x 0 size coal (from CT-1| in
Pennsylvania) with a natural cut point at about 1.70 Sp. Gr.
In this case, washing would recover theoretically about 85.756
washed coal with 0.78$ total sulfur. In actual washing, of
course, there will be some deviation from this yield depending
upon the washing efficiency of the equipment used.
Although only a few of the subject coals can be washed at the
iV x 0 size, it is obviously much more economical to wash coal
at coarser sizes than at 3/8" x 0 or ll+M x 0. Coal from CT-ljJ.
in the State of Ohio, as shown in the Figure 8, could be washed
at IV x 0 size to attain a sulfur level of less than l.OOjf.
At about 1.1)5 Sp. Gr., this size would attain a theoretical yield
of 88.2^ containing 0.91$ sulfur.

At the other extreme is the example of Lower Cherokee Seam
from BM-31 of Iowashown in Figure 9. In this case, a low
sulfur level can be obtained only by washing lljM x 0 size coal.
At a Sp. Gr. of about 1.14.0 the theoretical yield would be 89-2$
with an 0.91$ sulfur content. At IV x 0 or 3/8" x 0 sizes,
the sulfur content would be 1.27/2 and 1.09$ respectively when
washed at the same specific gravity of 1.1|0.
Figure 10 illustrates an example (CT-J>lj. in Illinois) of a
coal difficult to clean. Sulfur in the raw coal is 1.32$ and
the sulfur particles are so intimately mixed with the coal that
it is not possible to reduce the sulfur content in the washed
coal to 1.0$ even when washing a lljM x 0 size; at 1.60 Sp. Gr.
the theoretical yield of this coal would be 79.1$ with 1.20$
sulfur, which means that it would not be worthwhile to crush this
coal to U]K x 0.
There are some coals which must be washed at a low gravity to
yield a low sulfur product. Figure 11 shows an example of such
a coal (BM-50 in Pennsylvania). Although sulfur in the raw coal
is 2.38$, washing at about 1.35 specific gravity will theoretically
yield 91.0$ washed coal with only about 0.80$ sulfur.
Some of the other coals from the HEW washability data should be
treated at a high specific gravity; the coal from CT-21 in West
Virginia should be washed at a specific gravity higher than
1.70 to get a theoretical yield of more than 90$ washed coal with
leas than 1$ sulfur. Figure 12 shows the waghability curve for
this coal.
Approximately one-third of all the coal for which washability
data has been supplied cannot be washed to less than the highest
sulfur level of 2.50$ as specified by HEW. A washability curve
of such a coal (from BM-55 in West Virginia) is shown in Figure

The above examples illustrate the wide variety of coals to be
washed in the prototype plant. Keeping in view the complexity of
washing so many coals with such widely varying characteristics,
the prototype plant must be designed with sufficient flexibility
to remove pyribe frnm raw coal under a wide range of conditions.
The plant will, therefore, have a heavy media cycloid for treating
1-1/2" x 0 coals; or coals at a low cut point (down to 3/8" x 0
size) or coals with high near gravity material. McNally Visman
Tricones will be provided to clean 3/8" x 0 and smaller size coals,
or coal requiring treatment at a high specific gravity. Both coal
and mineral tables will also be provided to give added flexibility.

SECTION 5
RANKING OF COAL
A method has been developed for the ranking of coals from the
theoretical recovery of clean coal and total sulfur content of
the clean coal from the available washability data. In arriving
at this method of ranking, the following considerations were
made:
(a) Theoretical recovery of clean ooal.
(b) Total sulfur in the clean coal.
(c) Size of ooal cleaned.
A key to the ranking of ooals is given below. Table VII uses
this key to show the ranking of coals for the States of Alabama,
Illinois, Indiana, Iowa, Kansas, Kentucky, Maryland, Missouri,
Ohio, Pennsylvania, Tennessee and West Virginia, from the data
supplied by HEW. The rank of each coal shown in Table VII indi-
cates the recovery range of the washed coal, total sulfur level
in the washed coal, and the size of the coal washed.
The original reserves of coal seams for the States of Ohio, West
Virginia, and Western Kentucky are indicated for each seam. The
reserve figures shown against each mine in Table VII indicate
coal reserves of the seam in the state. We were asked to obtain
coal reserves for the major seams in the states of Ohio, West
Virginia, and Western Kentucky, which were obtained from the Ohio
State Geological Department, West Virginia State Geological
Department and Tennessee Valley Authority respectively. Table
VIII indicates the coal reserves for the major seams in these
three states.

It can be seen from Table VII that the best coal is ranked as
2A, or 3A-, and that the less desirable
A.^ series,; i.e., Lnj, t-n^, wi- j^
ones are in the C,- series such as
2C, or 3C^. Rank of coal
from uhe Table VII can be interpreted to suit the requirement

less than 1.00$ is assumed:

For example. Ranking 1B2 of BM-91 of Alabama, the "l" means lV' x 0
size raw coal; the "B" indicates a coal which when washed would
yield a clean coal recovery of between 50/6 and 75$, the subscript
"2" means that the total sulfur in the clean coal would be between
1.00# and 1.50#. Similarly, 2A1, of BM-93 in the State of Alabama
signifies a 3/8" x 0 size raw coal which when washed would yield
a clean coal in the range of 75/6 to 100$ having a total sulfur
content in the clean coal of less than l.OjJ.

SECTION 6
PROTOTYPE PLANT DESIGN
The design of the prototype plant, the requirements for which are
outlined in the Contract, requires special consideration to assure
that it will suitably process a wide variety of coals from which
to produce satisfactory clean coals with acceptable sulfur content.
The plant should therefore be very flexible with alternate circuits
and equipment choices which can be run in any combination so that
it will be able to handle coals of different sizes and widely vary-
ing washability characteristics. Recovery and concentration of
pyrite also requires consideration for possible future commercial
utilization. In the absence of established standard methods of
the recovery of pyrite from the waahery refuse, alternate circuits
as well as alternate equipment items are required to determine the
most suitable process for any given coal. All of these points have
been considered in completing the prototype plant design. The
.equipment and its operation are outlined briefly in the following:
(The plant flowsheet C-U527 included in the Synopsis should be used
to follow this description; for convenience the unit numbers from
the flowsheet are indicated in the description).
The process starts with the ROM coal crushed in a rotary breaker (8)
and a crusher (Ij.) and stored in one of the two steel silos (19)ซ
each having a capacity of lj.000 tons. Eight thousand tons of raw

Tailings from the magnetite separator (60) and the minus 1/2mm
fraction from the classifying cyclone (83) underflow are processed
in the flotation cells (9)4.) to recover low sulfur ooal from the
gangue material. Flotation cells are provided in the plant to
determine the feasibility as well as efficiency of recovery of low
sulfur ooal from pulp containing pyrite and coal. In case the
pulp is not required for further processing, the flotation cells
oan be by-passed and pumped to the waste pond through the tailings
sump (101) and the settling cone (128).
The flotation concentrate, or ooal, If found low In -sulfur, will be
filtered (97) and mixed with the coarse washed ooal and conveyed to
loading. If the ooal concentrate from the flotation cell is found
high in sulfur and not worth recovery, the filter will be by-passed
and the concentrate diverted to the waste pond.
Proper reagents to activate coal selectively and depress pyrite along
with other gangue materials present in the ooal slurry feed to the
flotation cell have not yet been developed for all different types
of coals. Work is being done in this field. The prototype plant
will give an excellent opportunity to carry out tests with the
various types of coals selected for processing; thus it may be
possible In the operation of this plant to find a suitable activat-
ing agent for selective flotation of coal. This would not only
provide valuable Information for the recovery of low sulfur ooal
and pyrite, but would also improve upon present techniques in the
recovery of low sulfur coal.
Adequate arrangements for the recovery of the magnetite from the
dilute medium have been provided. The dilute medium will be
thickened in a thickener (51)-) and the magnetite recovered by a
double drum magnetite separator (60) for reuse in the system.

As the washed coal is expected to have a high surface moisture,
we recommend that consideration be given to the installation of
a fluid bed type thermal dryer to dry the fine coal.
Installation of a dryer for this fine coal will generate valuable
information on:
(a) Fuel consumption versus dust loss when operating with
various velocities.
(b) Size analysis of the dust lost to the atmosphere.
(c) Size, analysis from the dryer to the primary dust
collector .
(d) Size analysis of the product over the grate.
(e) Size analysis of the product from the primary cyclone
dust collector.
(f) Selection of dust collecting equipment required to meet
the dust emission code of various states.
(g) Concentration of sulfur in the scrubber effluent.
(h) Loss of solids with the scrubber effluent.
(i) Change in sulfur content of the dried product versus
the dryer feed.
The above information will be valuable to meet the anti-pollution
requirement in designing a full-scale plant.

SAMPLING & TESTING
1 . Detail on Sampling and Testing;
Adequate testing arrangements have been provided in the plant
to evaluate each coal selected for processing, and to evaluate
the performance of individual equipment as well as the whole
plant. The purpose of testing program is:
(a) To evaluate performances of each major piece of
equipment used in the plant.
(b) To evaluate each coal selected for processing.
(c) To evaluate overall performance of the plant for
cost analysis.
(d) To make comprehensive plant studies including
material balances, ash, total sulfur and pyritio
sulfur content for each coal.
In order to provide adequate test data, the plant will be provided
with twenty-nine (29) sampling points, twenty-seven (27) automatic
solid and pulp samplers and two (2) manual sampling arrangements.
Raw Coal Tests: Approximately 8000 tons of each test coal will be
delivered to the plant. As the first lj.000 tons is crushed to 1-1/2"
x 0, a raw coal sample will be collected during one to two weeks
prior to the start of each test.
This sample will be collected by an automatic sampler and will be
based on sampling lots at 2800 tons in seven (7) hours and ij.00 TPH
feed. Sampler will take nine (9) cuts per hour at 55.6 pounds per
cut for a total sample of 500 pounds per hour. Samples will be
sent to two bins set to receive alternate cuts for a total of 250
pounds per hour to each bin.
(The material reporting to the rock bin from the rotary breaker
will be weighed, hand sampled, and analyzed for percent ash,

This will satisfy all conditions for ASTM D2234-65T on Mechanical
sampling of coal and D^920l$ sampling coals classified according
to ash content. It will also provide the proper gross sample to
make the washability study from which plant settings can be made.
The primary gross cample will be screened to produce the following

the following gravities: 1.30, i.35, 1.^0, 1-50, 1.60, 1.90, 2.20,
2.50 and 2.80. The refuse will be visually examined to see if
heavier gravities are required.
Dry ash, total sulfur and pyritic sulfur will be run on each siz

Page 38
The afternoon (P.M.) samples will be used only for material balance
of the plant in terms of percent ash, sulfur and pyritic sulfur.
Laboratory flotation tests will be made on all feeds to the
flotation cells, using reagents to be selected at a later date.
All siza and gravity fractions as well as flotation fractions
will be analyzed for percent ash, total sulfur and pyritic
sulfur.
All test work or daily runs will be completed no later than 5:00
A.M. the following day, at which time the raw data will be fed into
a computer for processing. During separate circuit testing the
completed report for the previous day's run will be available
for operating personnel by 7:00 A.M.
Procedures for Processing Samples: The various automatic samplers
have been numbered on the plant flow sheet for the sake of orderly
planning and discussion of the treatment of individual samples. A
coded system will relate samples to samplers, coal being processed,
tests run, size of product and date of test. It is anticipated that
drying of samples will be done by microwave techniques, which is a
process for continuous and rapid drying of wet samples without
induced heat.

5. Total Plant Circuit;
After the various plant circuits 'are set for their best
performance in sulfur reduction, at least three prolonged
runs will be made with all sampling stations of all
circuits in use so that a complete plant evaluation can
be made of each run. In addition to the sizing-gravity
separations, and ash, sulfur and pyritic analyses, actual
separating gravities and efficiencies of separation may
be determined together with plant material balances.
The plant feed and final cleaned coal products will have
a complete analysis made as shown on the attached CT&E
form to determine how removal of various components is
likely to alter burning and slagging characteristics of
the final product. A minimum of one run must be made
for the total plant after all circuits have been set at

The McNolly Pimburg Mfg. Corp. Proposal No. 62521
Pag,
Page lj.1
NOTE: This means that for every coal tested there should be a
minimum of four test runs made at a single feed rate ohosen
for each circuit in the plant. On the other hand, tripli-
cate runs could be made for each change in type of feed or
setting of equipment if confirming data is required for
statistical reliability. It would thus be possible to
make more than 100 runs on each type of coal delivered to
the plant without exhausting the technological capabilities
of the plant or the technical reasons for making the teat
runs.
Due to the volume of samples scheduled to be processed, it
is the intention routinely to sample makeup water and plant
effluent as well as any pond water or streams which might
be affected by the plant operation, then to process such
samples in one of CT&E's Laboratories. Comprehensive
aaaijaia (See page Itl) of feed and products will also be
processed by one of CT&E's Laboratories normally handling
this type of work. The cost of these additional analyses
would be at standard CT&E prices.
A complete test schedule for testing a candidate coal every
month is given in-Page 14.3.
If deemed advisable, provision can be made at additional
cost to include the following additional types of testsi
1. Abrasiveness test of raw and clean coal products to
determine benefits of removing pyrite.
2. Thermo-gravimetrio and differential thermal analysis
to determine ignition temperatures and profiles of raw
and clean coal products.
3. Neutron activation analysis for trace elements of raw
and clean coal ash contents obtained by low temperature
ashing techniques. These data could be the basis for
correlation studies of particulate air pollution and
high temperature reactions in combustion gases.

2. Testing Program:
The testing program has been designed to permit comprehensive
coverage of all sampling stations or only a few stations as
may be dictated by coals and circuits being tested. Sufficient
personnel and equipment will be provided to perform all
necessary tests on a day's run prior to the start of the next
day's run. Both equipment and personnel are excessive if only
one circuit is being tested. However, it must be recognized
that in addition to the daily testa, a washability is required
prior to each program for each coal. Furthermore, at the end
of each month there will be one or more comprehensive plant
studies including material balances and ash, sulfur, and pyritic
sulfur balances. This work will require substantial personnel
and will have to be performed at hours when it will not inter-
fere with the routine tests.
The laboratory staff will in addition to maintaining the plant
testing program regularly collect samples of water for analysis
comparisons of plant make-up water as well as effluent water.
All water coming onto the property and leaving the property
will be checked.
A monthly test schedule is given in Page 1).3ซ

Storage of Data;
During the operation of the pilot plant for three years,
valuable information on the reduction of sulfur for various coals
will be generated. A substantial amount of test and operational
data will also be available on the plant as a system as well
as on the various Individual regular items of equipment. This
data needs to be preserved in proper order for future use.
Besides this, these data must be properly catalogued and stored
in a manner which will assure ready access for current use
during the test program. For these reasons, it has been
considered wise to include a microfilming arrangement together
with an automatic storage and retrieval system as a part of
the office equipment provided for the laboratory and test
equipment.
Detail on the data handling and storing is given below:
(a) Bata Collection
Standard Register Company Key Punches in plant and lab.
where data is generated.
Key punches 80 column Hollerith preprinted cards with
soft copy snap-out for checking against print-out of
items punched.
(b) Data Input Transmission

connected via telephone circuits (cable, micro-wave,
or telestar) to off-site G.E. 600 computers for re-
mote batch and/or time-sharing service available 214.
hours as needed.
Back up will be provided by two terminals on site
with access to alternate computers via transmission
of duplicate punched tape programs kept for emergency
in office at plant site. Main programs will be stored
in off site computers.
The McNally Pimburg Mfg. Corp. Proposal No. 62521
Page W
NOTE:
(c)
One terminal will be high speed Model 105 Remote term-
inal equipped with Card Reader with capacity of reading
600 cards per minute with input data being compiled
and buffered for transmission to off site computers via
two channel voice grade telephone lines at rate of 125
cards per minute or via four channel lines at rate of
250 cards per minute.
Four channel lines can receive and send at the same
time whereas two channel lines can only send when not
receiving or receive when not sending. In other words,
four channel lines are simultaneous in-out lines.
The second terminal will be a G.E. Termi Net 300 that
can send or receive at 30 character per seconds, either
from punched paper tape or punched cards. Although a
much slower terminal than the Model 105, it is twice
as fast as the 15 character per second terminal usually
used by IBM for time sharing and three times as fast
as the 10 character per second Model 35 teletype terminal.
The Teimi Net 300 terminal will be used to process data
through-out the day, and the Model 105 will be used to
give a high speed completion of calculation in the last
two hours (5 AM-7AM) before the next day's operation
begin.
Data Computation
Two systems will be available for handling input data:
Series 600 3D Resource Remote Batch for handling data
from either terminal.
Series 600 Mark II Time Sharing for handling data from
the Termi Net 300 terminal.
Choice of Basic or Fortran languages are available for
either system, and programs will be written in the most
efficient language for specific programs. Probably some

(d) Data Output
Sach terminal will be equipped with fan-fold ratchet
feed paper for hard copy output, which will be for-
matted for Xerox printing on preprinted report forms.
Xerox Models 2lj.OO or 3600 will be used for this
printing, after the computer output has been checked
for accuracy.
The printers will handle 118 characters per line min-
imum, 136 characters per line maximum, two lines per
second on the Model 105 and four seconds per line on the
Termi Net 300.
(e) Data StoraKe
Xerox printed hard copy will be micro-filmed, using an
Eastman Kodak Model RD 3 Micro-filmer with capacity of
200 lines per second.
Processing of the film will be handled by Kodak Model
DVR Prostar Processor, and viewing on Kodak Model PE 1A
Reader-Printer (30 seconds per page).
A 100 foot roll of 16 mm film will hold 3000 pages of
data or about one weeks' output at maximum testing rate.
Viewing can be accomplished when required at a rate of
eight feet per second.
Film storage will be in coded magazine (closed container)
filed in metal cabinets designed for this purpose-800
rolls per cabinet.
(f) Data Retrieval
General Electric Closed Circuit Video system will be
used to provide access from the plant control room to
needed data stored on microfilm in the office. Voice
communication between plant and office will be pro-
vided by telephone cabled inter-corn system.
The video system will consist of an 8?5 line Model
WE21A2AA GE camera (in the office) cabled to a GE
Model Conrak C2P17 8?5 line Monitor with video am-
plifier (in the plant control room).

This system will prevent unauthorized access to data
stored in the office since hard copies of data can be
held to a minimum and video output will not be perma-
nent .
A Xerox copyflow can also be provided, if necessary,
for high speed print-out of microfilm rolls (20 feet
per minute). This would be an additional cost of

The proposed pilot plant will have its own laboratory facilities.
Besides its own facilities, the plant will also have access to
the well equipped testing laboratory of Commercial Testing and

There is rail-head facility available in the plant for bringing
raw coal to the plant as well as for transporting washed coal
from the plant. The rail track will have facility to accommodate
up to 1^.0 raw coal cars at one time. Although the existing plant
is out of cozmnission, the building, hoppers, settling cone and
some of the equipment are still available in good condition for
use in the proposed pilot plant.

COST ANALYSIS
A. ESTIMATED CAPITAL AND THREE-YJSAR OPERATING COSTS FOR THE
LABORATORY
The recommended pilot plant has been designed with a laboratory
with adequate sampling and testing facilities to assess coals
with a broad range of characteristics as well as the efficiency of
the plant and its principal items of process equipment. Since the
sampling and testing facilities provided in the laboratory have
been explained earlier, they will not be detailed here but a summary
of the equipment Investment and the laboratory operating costs
are given.
The following documents, prepared by the Commercial Testing and
Engineering Company are used for reference:
1. Sampling - Analysis Matrix
2. List of Equipment
3. Estimated Operating Cost
!).. Estimated Start-Up Cost
5. Start-Up Supplies
Since in the event the proposed plant is to be constructed and put
into operation and since it is expected that The McNally Fittsburg
Manufacturing Corporation will be the prime contractor for the
plant construction and operation of the project, a nominal overhead
and profit has been added to the costs estimated by C.T. & E. as
explained below:
(a) The total estimated investment for the equipment shown
under the Sampling - Analysis Matrix is $510,605.05. To
this an overhead and profit has been added at the rate of
five percent ($%) plus five percent (%%) respectively,
making a total of $56lj.,353.00. Add $513,838 for building,
electrical wiring, erection of laboratory equipment, etc.,
making a total $1,078,191.* The price of the equipment
has been included at the current prices quoted by the
-------
The McNally Pitfcburg Mfg. Corp. Propotal No.
Page 51
(b) It is estimated that the total laboratory personnel
requirement will be 62 for the various operations per
the detail shown under Sampling - Matrix. The estimated
wages of the laboratory personnel have been based upon
the prevalent rates of the TJ.M.W. in the State of
Indiana.
(o) .The C.T, & E. s.tart-up cost is estimated 'to be $798,660.00
and on adding overheard and profit at-the .rate-of five
percent (55?) and eight percent (8$) respectively, the
total cost comes to $911 ,5114-.00. It is estimated that
the starting-up and debugging of the plant will require
four (Ij.) to six (6) months.
(d) The total annual operating coat of the laboratory is
estimated to be $1,514.8,560.00. This does not include the
cost of utilities such as water, gas and electricity.
The estimated annual cost for the utilities is $37,314-0.00.
Therefore the estimated total annual operation cost
including utilities comes to $1,585,900.00. Adding over-
head and profit at the rate of five percent (5$) and
eight percent (8$) brings the estimated total up to
$1 ,810,000.00.
Estimated cost of running the laboratory per ton of raw coal
washed:
I. It is envisaged that at the rate of 50 tons of raw coal
per hour, one shift a day and 22 days a month, 8000 tons
of coal will be washed per month, which means 96,000 tons
per year. Considering a six months start-up period of the
plant at a 50jฃ operating rate and at a full 50 TPH for the
three years, the total raw coal processed in 3-1/2 years

II. Cost of R.O.M. Coal
(a) Assuming 80$ raw ooala coming from the eastern region as
Pennsylvania and West Virginia States, 10$ from the aouthern
region as Alabama and Oklahoma atatea and 10$ local coal is from
the state of Illinois. Therefore the average freight from these
regions would be:
Eastern Region - $(5.19 + k.82) = $ 5.00
2
Southern Region - $(16.kO +17.60) = $17.00
2
Local, i.e. Illinois - $3.00
The average freight rate to transport raw coal from these three
regions would be - 80$ of $5.0 + 10$ of $17.0 + 10$ $3.0 or $6.0.
Therefore the price of ROM coal delivered at Terre Haute, Indiana
is $6+1)..50 = $10.50.
(b) At the rate of 50 tons of raw coal per hour, one shift a day and
22 days a month, 8000 tons of coal will be washed per month, which
means 96,000 tons per year. Considering a six months start-up
period of the plant at a 50$ operating rate and at a full rate of
50 TPH for three years, the estimated total raw coal procesaed in
3^8 years would be:

ECONOMIC FEASIBILITY
Page 60
Aside from the great desirability of eliminating pollutants
from the air we breathe, the air pollution abatement requirements
by various Federal laws now in force place the consumers of coal
in a position of having to solve the problem of reducing SOg
content in the flue gas.
As indicated earlier, electric utilities are the largest single
category of coal consumers and, of course, air pollution control
effects will be needed most in the densely populated industrial
areas of states like California, Indiana, Illinois, New Jersey,
New York, Ohio and Pennsylvania. The larger industrial coal
users along with the public utilities can likely justify the
installation of flue gas cleaning processes to recover sulfur
and thus reduce the SOp content of the stack emission to acceptable
levels. Smaller industrial coal users in these industrial areas would
be obliged to burn low sulfur coal as the most economical solution,
in spite of the higher cost, if they are to meet air pollution
control regulations. Relocation of their plants in less densely
populated areas where the need for air pollution abatement is not
so stringent would be only a temporary solution since air pollu-
tion control requirements will most likely be increased in all
industrial areas in the next few years. Thus the demand for low
sulfur coals will surely increase as fast as the supply, which
means that there will be more and more pressure in the immediate
future for developing improved, economical methods for removing
sulfur from coals.
From the data made available to us by the Air Pollution Control
Division of HEW, we have given study of the economics of produc-
ing low sulfur coals careful consideration; although we do not
have sufficient cost data, we can outline the possible credits
which may be realized from using conventional methods of reducing

Tables II to VI show various coals whose sulfur content could be reduced
substantially through normal beneification methods. Outside of
meeting the need for sulfur removal, the reduction in ash content
of the coal during beneficiation alone, in most cases, will Justify
these costs because of: (1) the increase in BTU content; (2) the
reduction in weight prior to shipment; and (3) the substantially
reduced cost in ash disposal costs at the point of usage. Thus,
it can be said that the conventional coal beneficiation operation
will, depending upon the washability characteristics of the coal,
pay for itself fully in most cases by the increase in value of the
washed coal, the meeting of the essential requirement for sulfur
reduction being a substantial, added benefit Another valuable
by-product in many cases, again depending upon the coal characteristics,
will be the recovery of pyrite from the coal refuse stream.
The economics of using low sulfur coals depends upon the following:
(a) Reduction in ash during beneficiation process
(b) Sulfur content in the raw coal
(c) Ease of removal of sulfur from the coal
(d) Sulfur level in the washed, coal
(e) Price of low sulfur coal
(f) Credit for pyrite produced
(g) Tonnage rate of coal washed
(h) Freight costs in transporting raw coal (if coal preparation
plant is not at the mine)
(i) Freight costs in transporting washed coal to point of
usage
These points are explained in further detail below:
(a) Reduction in Ash During Beneficiation Process
As indicated above, there are other advantages in the
reduction of sulfur content of raw coal to meet air pollution
requirements. The process of reducing the sulfur in coal also
reduces the extraneous ash bearing mineral matter. It is
usually easier to remove the ash than it is to remove the
sulfur, but the normal beneficiation process for ash removal
does reduce the sulfur sufficiently in many cases to meet
air pollution control requirements. If it is necessary to
decrease the sulfur content beyond that obtained through
normal ash removal operations, the further sulfur removal will
also likely reduce the ash content to a lower level, but at
the cost of a lower yield of washed coal. FOR EXAMPLE,
Figure 11). shows curves for CT-29 in Pennsylvania.
Washing this coal to 10# ash content, which is normally a
satisfactory ash level, for steam coals, would give a theoretical
recovery of 81 .$% with a total sulfur content of 1.32$. Of
course to obtain a 1% sulfur level in the washed coal, the
theoretical recovery would be only 50g with a 5# ash content.
This amount of sulfur reduction would therefore be very
costly.
The curves of Figure 15 show another example in which a 10#
ash content tor CT-28 in Pennsylvania, the theoretical
yield would be 78.7# with a total sulfur level of 1 .S2J< in the
washed coal. To bring this sulfur level down to 1.00ฃ would
again be costly, since the recovery would be reduced to 3l4..3#
with an ash level of \.Z%.
These two examples also show cases in which to achieve a
satisfactory recovery the ash content should not be reduced
below about 10$ and in which the sulfur content at that ash
level is at a reasonable level.
(b) Sulfur Content in the Raw Coal
The nature and the amount of the sulfur present in the raw
coal has an especially important bearing upon the economics
of the beneficiation process. To meet a low sulfur level in
the washed coal requires that the organic sulfur content in
the raw coal be less than the sulfur level desired in the
washed coal. As an example, if the washed coal is to meet a
maximum level of a \% total sulfur content, the raw coal must
not have more than a content of "\% of organic sulfur. Since
organic sulfur is usually present in coal in a disseminated

beneficiation process. On the other hand, high recoverable
pyrite from the raw coal is desirable from an economic point
of view since the recovery of pyrite as a by-product would
contribute towards the cost of washing the coal.
(c) Ease of Removal of Sulfur From Coal
In the reduction of sulfur to meet air pollution criteria,
the coals selected should have easily removable sulfur in
the raw coal. As indicated previously, organic sulfur and
sulfate sulfur are intimately mixed with the coal. Pyritic
sulfur occurs in coarse particles, in bands, in pockets and
even in finely disseminated form; only the finely divided
and intimately mixed pyrite particles which form an inherent
part of the coal are impossible to remove by present conventional
beneficiation processes. Therefore, pyritic sulfur in coarse
form and occuring in bands or pockets is desirable for the
success of the normal washing process.
As illustrated earlier, the removal of pyritic sulfur from
raw coal also depends upon the siiv, -f -the coal to be washed.
While it might not be possible to remove pyrite sulfur from
a given raw coal crushed to 1-1/2" x 0, most of it could be
removed when it is crushed to 3/8" x 0. Crushing of raw coal
to a finer size for removal of sulfur is an expensive proposition
and generally not worthwhile from economic point of view.
(d) Sulfur Level in Washed Coal
The economics of the removal of sulfur from a raw coal depend
upon the criteria set by the air pollution control authorities
for different areas. The lower the sulfur level required in
the washed coal, the higher will be the cost of washing due
to the lower recovery of the washed coal. It is therefore,
prudent to select the proper raw coal so that the reduction
of sulfur to a desired level will not be done at the cost of
too low a recovery of washed coal.
Ttw McNally Pittsburg Mfg. Corp. Proposal No.
Pag. 66
(e) Tonnage of Coal Washed
The amount of coal to be washed depends upon factors like
financial resources, availability of raw material near to
the preparation plant, and the demands for low sulfur coal
and pyrite. Normally, the larger the capacity of a plant,
the lower will be the operating cost per ton of coal washed.
(f) Price of Low Sulfur Coal
Thซ pr -i.jn in price for low sulfur coal is one of the most
important factors required for the coal companies to justify
l.ives-ment in coal preparation plants for sulfur reduction,
especially in those cases in which to achieve the desired sulfur
level the coal characteristics require washing at a lower
yield than would be necessary to reach economical ash levels.
The price premium for low sulfur co'-.I at present does not
justify any appreciable investmen' jut it is anticipated that
the more stringent air pollution requirement of the future,
when suitably enforced, will create a much greater demand,
even at an enhanced price, for the low sulfur coals. Besides
conforming to the air pollution requirements, the low sulfur
coals will have the following additional advantages:
I. Lower pulverization cost due to lower pyrite content.
II. Reduction in corrosion in the boiler tubes, preheaters,
etc. because of the reduction in the abrasive index
of the washed coal, again due to the lower pyrite
content.
(g) Credit for Pyrite Produced
The pyrite produced as a by-product could be sold to the
sulfuric acid manufacturers or used in other sulfur processes
to recover a portion of the beneficiation costs.
(h) Freight in Transporting Raw Coal
Freight involved in transporting raw coal can play a significant
part in the economics of the process; obviously longer the
distance the raw coal has to be transported, the higher will
-------

that the coal preparation plant be centrally located and, if
possible, near to the raw material and to the clean coal
market.
(i)
Freight Costs in Transporting Clean Coal
The presently known low sulfur raw coal reserves are generally
in the Pennsylvania, West Virginia, Kentucky and Ohio areas.
This means that higher sulfur raw coals in other areas will
likely have to be beneficiated to reduce the sulfur to accept-
able levels. Thus transportation costs of the washed coal will
affect the economics of such operations.

CONCLUSION. ACKNOWLEDQEMBNT & BIBLIOGRAPHY
SECTION 1
CONCLUSION
As explained earlier, the objects for considering the construction
and operation of the proposed pilot plant are:
(a) To demonstrate in actual practice, the percentage of
reduction of total sulfur and pyritic sulfur for a given
recovery of washed coal from a raw coal selected for
processing; it will also be possible in this way to obtain
a comparison of actual performance to the predicted
performance based upon results obtained from the testing
of bulk samples.
(b) To demonstrate the percentage of recovery of pyrite from
the washery refuse for various coals.
(c) To select a suitable process as well as iter^j of equip-
ment for maximum recovery of washed coal at a given
sulfur level.
(d) To evaluate the cost of washing in a commerlcal size
operation for each coal processed.
To meet the above requirement, a test/pilot plant with the best
available processes in current use in coal preparation technology
has been designed. Being a pilot plant for an extensive testing
program, flexibility has been designed into the circuits as well
as in the choice of the process equipment to assure proper assessment
of the wide range of washabllity characteristics likely to be
encountered in the operation of this plant.
Because of the continued growth of mechanical mining practices,
more complex coal cleaning plants are required in order to remove
the extra ash bearing and other extraneous material and to treat
the larger quantity of coal fines produced. In the process of
reducing ash in coal, a portion of the sulfur (depending upon its
nature) present is also removed. Compared to ash removal, sulfur
is usually more difficult to remove because of the nature of the
sulfur content in the coal. Therefore the reduction of sulfur to
a level of less than 1.$% in clean coal is achieved in most cases

Work on the reduction of sulfur from coal haa been attempted
through crushing, screening, gravity separation, froth flotation,
tabling, electro-static separation, electro-magnetic separation
and in many other ways. Some of these processes do yield satis-
factory results in the reduction of sulfur, almost always depending
upon the characteristics of the sulfur in the coal. But there is
currently no suitable conventional, economical process for
removing the finely disseminated pyritie sulfur or organic sulfur
from the raw coal; it is usually accomplished only at a substan-
tial sacrifice in the yield of clean coal.
Another major factor in the demand for coal's sulfur reduction
will be for the gasification and liquefaction of coal. The
present demand for petroleum products in this country is about
four billion barrels per year and by I960 this demand will be
six to eight billion barrels; by the year 2000, twelve to fifteen
billion barrels per year (6). At the present depletion rate,
known oil reserves will last only until the 1980's. According
to the Institute of Gas Technology, Chicago, Illinois, known
gas reserves in this country are approximately 300 trillion
cubic feet; the net addition to the U.S. reserves have been
very low in recent years. At the present rate of consumption,
known gas reserves will last for another 15 year (27). In the
U.S.A. the minimum projected demand for gas through the year
2000, assuming that the gas can be made available, totals over
1000 trillion cubic feet.
Known coal reserves, by contrast to the above, will last until
22&0's (23). The obvious replacement for these depleted oil
reserves is coal, which is the reason for the current development
activity in this field. To meet the requirements for petroleum
products and natural gas substitutes, as well as future anti-
pollution requirements, sulfur removal from the coal will be
necessary either during the gasification or liquefaction process
or prior to it.

Extensive work is being done by various organizations throughout
the world to find improved methods for reducing sulfur in coal,
but emphasis is greatest in the U.S.A. at this time due to the
great need for burning coal with low sulfur emission. Using
current preparation technology, the theoretical as well as the
actual clean coal recovery can be predicted at different ash
levels. Similarly the theoretical as well as the actual recovery
of clean coal can be predicted at different sulfur levels. To
be able to make these predictions, of course, will require exten-
sive field work in the collection of bulk samples, laboratory
tests to determine the washability characteristics of coal, the
extent and the nature of the occurrence of the pyritic sulfur in
the coal, the additional liberation of sulfur by crushing, and
the amount of the organic sulphur present in the raw coal.
From the detailed studies described In this report, made possible
by the extensive test data supplied through HEW, it is evident
that there are problems involved in meeting all of the testing
and operating requirements which have been uncovered by these
studies. Coupling these problems with the amount of test data to
be developed within the time periods outlined has culminated In
the design of an operating and testing facility requiring capital,
testing, and operating costs of magnitudes which deserve careful
thought and study before a decision is made to proceed with the
program as it has thus far been outlined. We would therefore
suggest that consideration be given to the following different
alternates:
1. A 50 TPH prototype plant has been selected for this study on
the basis of various discussions held with HEW officials. From
-------
The McNolly Pithburg Mfg. Corp. Proposal No. 62521
Page 71
that some consideration should be given to the construction of
a full scale commercial plant primarily because the capital in-
vestment will be much more effectively used in building the
larger plant. The laboratory costs would be approximately the
same in either case, and it would be of advantage to conduct
certain tests both at 50 TPH and at the commercial rate of 1000
TPH. At the end of the program the larger plant would be of
substantial value both from a scientific and commercial stand-
point. From a cost standpoint, administrative, office and labora-
tory personnel would be at about the same level for either a
test or a commercial size plant.
Because of freight costs involved in moving the test coals, it
would be desirable to do most of the test work at 50 TPH, but
the capacity would be available both for full scale testing
purposes or for Commercial operation on local or other coals
during non testing periods.
We suggest the question: Should a new commercial size operating
plant be constructed *fr>'ซb could treat and test, say, 1000 TPH,
but which would be designed with sufficient flexibility to handle
and t.est at low (50 TPH) feed rates?
Close cooperation with a large coal company would probably be
necessary to assure that the suggested alternative would become a
financial success; or this 1000 TPH test/operating plant might
also serve a very useful purpose if it were run as a cooperative
venture by a group of coal companies through the National Coal
Association or the Bituminous Coal Research. The additional
cost for the 1000 TPH test and operating capacity should be
worth consideration, especially if the 1000 TPH capacity could
be a deciding factor in the disposal of the facility through some
prearranged agreement with the operating coal company or group
of companies.

2. Since major contributions to both Capital and Operating Costs
are the laboratory and testing facilities and procedures, some
consideration should be given to the use of existing central
testing laboratories (with expanded facilities and manpower if
necessary), rather than to have to build all of the extensive
facilities which are contemplated by this study.
The laboratory and the large manpower requirement are to a major
extent dictated by the short operating and testing cycles which
have been set as objectives for each different coal. Obviously,
either fewer tests or the availability of a longer time period
for the completion of each set of tests would reduce both the
capital and the daily operating costs. In the final analysis,
such savings should be balanced against the present anticipated
requirement for complete and timely test results.
3. Another approach would be to seek cooperation from various
coal operators to use their cleaning plants which are strategi-
cally located in relation to the sources of the coals to be
tested; arrangements could be made to add temporary modifications
to the plant in question both by adding the necessary extra pro-
cessing equipment when required and any necessary sampling equip-
ment to assure the use of the proper cleaning methods and the
collection of samples of the coals at desired points in the plant.
These samples could then be tested at the nearest available,
suitable testing laboratory. If such sampling and testing pro-
cedures could always be supervised by the same personnel, this
would help to attain consistency of results for comparative
purposes; in any event, care could be exercised to assure the
meeting of accepted and consistent sampling and testing standards.
Ij.. Experienced coal washery contractors are able to predict
accurately ash, moisture and sulfur levels in washed coal, pro-
vided washability data is available on reliable samples of the
coal to be washed. This capability is based on the use of bene-

Pag. 73
or the fact that this study has produced no new beneficiation
processes whose effectiveness on a wide variety coals need to
be tested, we recommend that the proposed pilot and testing
plant not be built.
5. If extreme flexibility were required, the future full scale
plant could be designed to produce clean coal which would meet
the desired sulfur level requirements from a very wide'range -
of raw coals; as illustrated by this study, however, low sulfur
levels would sometimes be produced at high costs, either due to
having to clean the coal at fine sizes and/or at a sacrifice in
yield. This suggested approach, combined with some prior tests
on certain coal cleaning and pyrite separation equipment, should
be able to provide all of the results desired from this proposed
Pilot/Test Plant.
Some of the above suggestions, as indicated, have resulted from
the studies made under this contract and are, of course, offered
with the likely disadvantage of an incomplete background of
significant information which might affect you*- Ue'cislon as to
the best course of action.
6. As required by the scope of work, we are to give an estimate
of our costs to develop the estimated cost for analysis of data to
be generated by the prototype plant study and the estimated cost
to develop flowsheets and cost estimates for full-scale plants.
As the washability characteristics of 36 coals to be washed during
3 year period may vary considerably, it is not possible to predict
the number of different full scale plant flowsheets and cost
estimates required.
For the purpose of developing flowsheets from the data generated
in the prototype plant, we assume the following:
a) All plants will have the same capacity, say 1000 TPH.
b) Same design of raw coal receiving and handling system
will be used for all plants.
c) Sams type of clean coal loading system will be used.
Th. McNally Pimburg Mfg. Corp. PropOMl No. 62521
Pag, 7k
d) Maximum coal size 1-1/2" x 0, minimum 1ljM x 0.
e) Plant will be basically a heavy media cycloid and
hydro-cyclone type, and
f) Fluid bed type thermal dryer will be provided.
Taking the above assumptions Into account, our estimated costs
are as follows:
1) For 30# accuracy In the estimate (with a set of flowsheets,
a set of unit lists, and an approximate estimate of the
plant)
-$5,000 for the first plant and $2,500 for each
additional plant requiring a different flowsheet.
2) For 20J< accuracy In the estimate (with a set of flow-
sheets, a set of unit lists complete with specification,
sad an approximate estimate)
-$10,000 for the first plant and $5,000 for each additional
plant requiring a different flowsheet.
3) For 10# accuracy in the estimate (with a complete proposal
together with a set of flowsheets, unit lists, specification
of the plant and equipment, a set of 1/8" design drawings,
and a detailed estimate)
-$50,000 for the first plant and $25,000 for each additional
