                                  PREFACE

     The wood treatment engineering assistance project was funded by  EPA's
Control Technology Center (CTC).  The CTC was established by EPA's Office
of Research and Development (ORD) and Office of Air Quality Planning  and
Standards  (OAQPS) to provide technical assistance to State and local  air '
pollution  control agencies.  Three levels of assistance can be accessed
through the CTC.  First, a CTC HOTLINE has been established to provide
telephone  assistance on matters relating to air pollution control
technology.  Second, more in-depth engineering assistance can be provided
when appropriate.  Third, the CTC can provide technical guidance through
publication of technical guidance documents, development of personal
computer software, and presentation of workshops on control technology
matters.
     The engineering assistance projects, such as this one, focus on
topics of  national or regional interest that are identified through
contact with State and local agencies.  In this case, the CTC was
contacted  by the Virginia A1r Pollution Control Board with a request for
information about odor (and potential air toxics) control at creosote wood
treatment  facilities.  Specifically, the agency requested available
information on controls designed to limit emissions during the time the
treated wood is withdrawn from the retort and is cooled outdoors.  As a
result, the EPA's Emission Standards Division (ESD) contracted with the
Midwest Research Institute (MRI) to conduct an engineering evaluation of
the wood preserving process.  This report presents the results of that
evaluation.  The report discusses the history of the wood preserving
industry,  the various techniques used to preserve wood, and the air
emissions  associated with the Boulton process.

                             1.0  INTRODUCTION

     Wood preservation  is the pressure or thermal impregnation of
chemicals into wood to  a depth that will provide effective long-term
resistance to attack by fungi, insects, and marine borers.  By extending
the service  life of available timber, wood preservation reduces the
harvest of already stressed forestry resources, reduces operating costs in
industries such as utilities and railroads, and ensures safe working
conditions where timbers are used as support structures.
     The three preservatives predominantly used in the U.S. for wood
preservation are pentachlorophenol; creosote; and aqueous formulations of
arsenic, copper, chromium or ammonia.
     The wood preservation process deposits or fixes these chemicals in
the wood, and the toxic nature of the chemicals effectively prevents the
attack of living organisms on the wood.  Because the chemicals are also
toxic to varying degrees to humans and aquatic organisms, their use in
industry must be carefully controlled.  This document will discuss each of
the preservatives and the various processes used to treat a variety of
wood products concentrating on the use of creosote for the treatment of
crossties.  Of particular concern will be the emission sources associated
with the release of odor and air toxics and the technologies  currently in
use to control them.

-------
            2.0  THE WOOD PRESERVING  INDUSTRY—PAST AND PRESENT

2.1  HISTORICAL SKETCH
     The  need  to protect wood  from  various  forms  of decay  has  been
recognized  since ancient times.   The  use  of chemical  preservatives  to
perform this function did not  come  into widespread use  in  this country
until the early 1900's.  At that  time, the  expansion  of railroad  systems
throughout  the country created a  need for a durable,  weather-resistent
material  from  which railroad ties could be  made.  Wood treatment  with
creosote, an oily liquid mainly consisting  of aromatic hydrocarbons, was
found to  fill  the need, resulting in  large-scale  use  of creosote-treated
products.
     The  need  for a building material that  could  survive in marine
environments presented another use  for preserved  wood.  Again, creosote
was found to be effective in most instances, providing protection to
docks, underwater posts, and wharfs.  However, attack by the marine borer
Limnoria  trlpunctata, commonly known  as "gribble," can destroy creosote-
treated wharfs.  This led to the  discovery  that a dual treatment  of copper
arsenate  salts followed by creosote was successful in resisting gribble
attack.
     There was also a need for a  clean, more paintable product not having
the appearance or odor of creosote-treated "wood.  Therefore, an intensi-
fied search for alternatives to creosote was undertaken.  Two types of
preservatives were identified to  achieve this:  waterborne preservatives—
inorganic salts in a water carrier, and pentachlorophenol  (PCP)—a
crystalline compound applied in a light oil  carrier.   Both provided
protection from decay while producing a product that  could be used in many
applications where creosote-treated products could not.
     With treated  wood products successfully demonstrated,  utility
companies, construction companies, steamship lines, road maintenance
organizations, and various  other groups saw  potential  uses  for treated
wood.  These uses  would ultimately include poles,  pilings,  plywood,  fence
posts, guardrails,  bridge structures,  boardwalks,  and  other lumber and
timber products.   New demands  for treated  wood created a need for more
versatile products  and a much  greater  production capacity.

-------
2.2  CURRENT INDUSTRY STATUS
     A recent survey of the wood preserving industry reports that  588  wood
preserving plants were in operation in 1986.:  Most treatment plants (508)
used only one type of preservative:  414 treated only with waterborne
preservatives, almost all of which were arsenicals; 58 treated only with
creosote; and 36 treated only with pentachlorophenol.  The other 80 active
plants used various combinations of two or more preservatives.  The total
industry consumption of preservative and fire retardants in 1986 was
reported as follows:1
     1.  117 plants treating with creosote solutions consumed 89.9 million
gallons of creosote and creosote-coal tar, and 16.5 million gallons of
petroleum solvent to treat 119 million ft  of wood products.
     2.  96 plants treating with pentachlorophenol consumed 22.1 million
pounds of pentachlorophenol and 32.4 million gallons of petroleum solvent
to treat 50 million ft3 of wood products.
     3.  475 plants treating with waterborne preservatives consumed
130.8 million pounds of preservative salts to treat 375 million ft3 of
wood products.
     4.  79 plants treating with fire retardants consumed 24.6 million
pounds of fire retardant chemicals to treat 10 million  ft3 wood
products.  A more detailed products breakdown  1s presented in Table 1.
     Seventy-five percent of the' wood treatment plants  in the U.S.  are
concentrated in two distinct regions.   One area extends from east Texas to
Maryland and corresponds roughly to the natural  range of southern pines,
the major species utilized.  The second,  smaller area is located  along  the
Pacific coast, where Douglas fir and western red cedar  are the  predominant
species.  The remaining 25 percent of plants are scattered throughout the
U.S.  Table 2 presents  the distribution of wood  preserving plants  in the
U.S. in 1986 by State and region.   The production of treated wood  in 1986
is listed 1n Table 3 by U.S.  region for 518 reporting plants.  Table 4
presents the production data for pressure  treating plants  1n  1986 by type
of preservative used.

                     3.0  OVERVIEW OF WOOD PRESERVATION

     This chapter discusses the types  of  preservatives used to treat
various wood  products and the processes by which these preservatives are
applied.  The wood  treatment process generally has two stages, a
conditioning  stage  that serves to  remove  moisture from the wood (which
allows for greater  penetration of  preservative)  followed by a treatment
stage during  which  the preservative  is forced  into the wood,  usually by
means of pressure.
3.1  WOOD PRESERVATIVES
     Wood preservatives fall  into  two general  classes:  oils,  such  as
creosote and  petroleum solutions of pentachlorophenol, and waterborne
salts that are  applied as water solutions.   Preservatives vary greatly in
effectiveness and in  suitability for different purposes and use
conditions.   The effectiveness of  any preservative depends not only  upon
Its composition but also  upon the  quantity  injected into the wood, the
depth of penetration,  and the conditions  to which  the  treated  material 1s
exposed in service.2
     Table 5  shows  the types  of preservative oils  and  waterborne salts
that are used to treat various types of wood products  and  the  minimum
required preservative  retention (pounds of preservative  per cubic foot of
wood) for each  product/preservative combination.  Although  the majority of
wood products are treated with waterborne preservatives, this  report is
concerned with  the  odors  that  are emitted when creosote  or  creosote
solutions are used.  Therefore, the following discussions focus primarily
on creosote and creosote  solutions and the types of wood treatment
processes that use  these preservative oils.
3.1.1  Preservative 011s
     Creosote and solutions with heavier,  less volatile petroleum oils
often help protect wood from weathering but may adversely Influence its
cleanliness,  odor,  color, paintabllity, and fire resistance.  Volatile
oils or solvents with oilborne preservatives, if removed after treatment,
leave the wood cleaner than the heavier oils but may not provide as much

     3.1.1.1  Coal Tar Creosote.  Coal tar creosote, a black or brownish
oil made by distilling coal tar, is highly toxic to wood-destroying
organisms and has a long record of satisfactory use as a wood
preservative.  The American Wood Preservers'  Association describes
creosote, as used by the wood preservation industry, as:  "a distillate of
coal tar produced by high temperature carbonization of bituminuous coal;
it consists principally of liquid and solid aromatic hydrocarbons and
contains appreciable quantities of tar acids  and tar bases; it is heavier
than water, and has a continuous boiling range of at least 125°C,
beginning at about 200°C."'*
     The first fractions from coal tar distillation contain the light (or
low molecular weight) oils, and the residue left after completion of the
process is the pitch.  The higher boiling point liquid fraction recovered
between these two general classes of materials is creosote.  Relative
concentrations of creosote components can vary because the character of
the tar, details of the distillation process,  and proportion of distillate
included in the creosote fraction all influence the composition of the
creosote.  Table 6 summarizes the chemical and physical  properties of
creosote, and Table 7 lists the major components of creosote.
     Most of the 200 or more compounds in creosote are polycyclic aromatic
hydrocarbons (PAH's).  Only a limited number of these compounds (less than
20) are present in amounts greater than 1 percent.   The  major  polycyclic
aromatic hydrocarbons in creosote listed in Table 7 generally  comprise at
least 75 percent of the creosote.
     The many components in creosote complement each other in  effecting
wood preservation.  The lighter molecular weight PAH's  in creosote are
generally more toxic to decay organisms.   The  heavier molecular weight
components of creosote help "retain" the lighter, more toxic components
within the wood by minimizing leaching or volatilization.   The  heavier
residues of creosote, when impregnated into wood, prevent moisture changes
and subsequently minimize splitting  of wood.
     The advantages of coal  tar creosote include:   (1) relative
insolubility in water and low volatility,  which impart to  it a  great
degree of permanence under the most  varied use  conditions;  (2)  ease of
application; (3)  ease with which its depth of penetration  can be
                                    12

determined; and (4) general availability and relative  low  cost  (when
purchased in wholesale quantities).  Some disadvantages of coal  tar
creosote are:  (1) creosote-treated wood usually cannot be painted
satisfactorily, (2) the odor of creosote-treated wood  is unpleasant to
some persons, (3) creosote vapors are harmful to growing plants, and
(4) creosote-treated wood can cause skin irritation or burns when it  is
handled.3
     3.1.1.2  Creosote Solutions.  Either coal tar or petroleum  oil can be
mixed with coal tar creosote, in various proportions, to lower
preservative costs.  The creosote solutions have a satisfactory  record of
performance, particularly for crossties where they have been most commonly
used.3  Mixtures of coal tar and coal tar creosote commonly contain about
20 to 50 percent tar by volume.   In general, mixtures of  coal tar
creosote and petroleum may contain 30 to 70 percent petroleum by volume,
but the content is usually about 50 percent.2  (For crossties and
switchties, the tar content is about 40 to 50 percent.)3   Creosote-coal
tar solutions penetrate the wood with greater difficulty because they
generally are more viscous than straight creosote.  However, high
temperatures and pressures during treatment, when they can safely be used,
will often improve penetration of high viscosity solutions.
     Creosote petroleum solutions and creosote-coal tar solutions help to
reduce checking (splitting) and weathering of the treated wood.
Frequently posts and ties treated with standard formulations of these
solutions performed better than those similarly treated with straight coal
tar creosote.3
     3.1.1.3  P;ntach1oropheno1  Solutions.   There are several  types of
pentachlorophenol  solutions used in wood preservation:  mineral spirits,
heavy petroleum oils, and liquid petroleum gas are all solvents that can
be used with pentachlorophenol  for wood treatment.   Pentachlorophenol
solutions generally contain 7.5 percent (by weight) of this chemical
although solutions with volatile solvents may contain lower or higher
concentrations.
     The performance of pentachlorophenol  and the properties of the
treated wood are influenced by  the properties of the solvent used.   Heavy
petroleum solvents are preferable for maximum protection,  particularly
                                    15

-------
 where  the treated wood  1s used  1n  contact  with  the  ground.   The heavy oils
 remain 1n the wood for  a long time and  do  not usually provide a clean or
 paintable surface.  Therefore,  volatile solvents, such as  liquified
 petroleum gas and methylene chloride, are  used  with pentachlorophenol when
 the  natural  appearance  of the wood must be retained and the  treated wood
 requires  a paint coating or other  finish.
 3.1.2   Waterfaorne Preservatives
     Standard wood preservatives used in water  solution include acid
 copper chromate, ammoniacal copper arsenate, chromated copper arsenate
 (Types I,  II, and III), chromated  zinc  chloride, and  fluorchrome arsenate
 phenol.   Waterborne preservatives  leave the wood surface comparatively
 clean, paintable, and free from objectionable odor.   Typically,  they must
 be used at low treating temperatures (100° to 150°F)  because  they are
 unstable  at  higher temperatures.3
     The  chromated zinc chloride and fluorchrome arsenate phenol
 formulations are not as leach resistant  as other waterborne preservatives
 or oils and, therefore, are recommended  for above-ground, light-duty uses
 only.  The anaoniacal copper arsenate and chromated copper arsenate
 formulations are included in specifications for such  items as building
 foundations, building poles, utility poles, marine piles, and piles  for
 land and fresh water use.3
 3.2  CONDITIONING TREATMENTS
     With  most wood treating methods, the presence of significant amounts
 of free water in the wood cell  cavities  may retard or even prevent the
 entrance of the preservative liquid.7  Therefore,  the moisture content of
 the wood must be reduced prior  to treatment.  Moisture reduction can be
 accomplished by using artificial conditioning treatments or by allowing
 the wood to air-season (I.e., storing the untreated  wood outdoors in
 piles).  Unseasoned wood that is exposed to the  open air,  but protected
 from rain, will  gradually dry out until  it  comes into approximate
 equilibrium with the relative humidity of the air.   Frequently, timbers
must be treated  without  waiting  for them to air-season because of
unfavorable climatic conditions  or  because  rush  orders make  it necessary
to treat the wood  immediately.7
                                    16

-------
      Wood 1s conditioned by one  of  the following three primary methods:
 (1)  stearaing-and-vacuum, (2) bo11ing-under-vacuum (commonly referred to as
 the  Boulton process),  and (3)  vapor drying.  These conditioning treatments
 remove  a substantial  amount of moisture from the wood and  also heat the
 wood to a more favorable treating temperature.2   The steaming-and-vacuum
 process is employed mainly for southern pine, while the Boulton or
 boillng-under-vacuum  process is  used for Douglas fir and sometimes for
 hardwoods.  Vapor  drying is used for seasoning railroad ties and other
 products.3
 3.2.1  Steaming-and-Vacuum Process
      In the steaming process,  the wood  is steamed  in  the treating  cylinder
 (retort)  for several hours,  usually at  a maximum temperature of  245°F.3
 When the  steaming  is completed,  a vacuum is  immediately applied.   During
 the  steaming period, there is  practically no reduction  in the moisture
 content of the wood.   In fact, some water actually  is added by condensa-
 tion in the early  part of the  steaming  period when  the  wood is cold.2
      When the  steaming is discontinued  and a vacuum is  applied, the
 boiling point  is lowered and part of the water in the wood, especially
 that near the  surface, is forced out mechanically by the steam generated
 in the  wood cells  or is  evaporated during the vacuum period.  Most of  the
 water removed  by the vacuum after steaming 1s taken out during the early
 part of the vacuum period when the wood  is hottest and evaporation is most
 rapid.  From the standpoint of moisture removal,  there is little need to
 continue  the vacuum much  longer than 2 hours.
     Among  the principal  advantages of steaming  are:  steam heats the wood
 faster  than any of the other heating mediums; it  is easily  applied and
 requires  no special equipment; the temperature can be controlled easily;
 and  the wood is left clean after  steaming is completed.2
     The  principal  disadvantages  are:   wood  surfaces are exposed to the
actual  steam temperature during the  entire steaming period  (which could
damage temperature-sensitive woods); only a  limited amount  of moisture can
be removed  during the entire steaming period; and it is generally
necessary to use considerably higher temperatures than would be needed,
for example, in the use of the Boulton  process.
                                    17

-------
 3.2.2  Boulton (Boiling-Under-Vacuum) Process
     In the  Boulton process, the treating cylinder  1s  filled with hot
 preservative oil  so that all the timbers are covered  (although  some
 unfilled  space may be  left above the oil surface).  The  preservative is
 then kept heated  while a vacuum is applied.  In  this case,  the  oil  serves
 to keep the  wood  hot while the vacuum lowers the boiling point  of the
 water  in  the wood and causes part of the water to evaporate.2  The
 evaporated moisture and some of the accompanying vapors  from the  oil  pass
 through a condenser.  The condensate can then be weighed or measured  to
 determine how much water has been removed from the charge,  and  the
 volatile  oils evaporated from the creosote and condensed with the water
 may be separated  from the water and returned to  the preservative  tank.2
     The  vacuum during the boiling period usually reaches 22 inches or
 more, and the entire cycle may last anywhere from 10 to  36  hours.  The
 average temperature of the preservative during the Boulton1z1ng cycle
 typically ranges  from 180° to 220°F depending upon the type  of wood being
 treated and  Its Intended use.  This temperature  range, lower than that  of
 the steaming  process, 1s a considerable advantage 1n treating woods that
 are especially  susceptible to Injury from high temperatures.7  In general,
 the minimum,  rather than the maximum,  specified temperatures are used and
 the boiling period 1s only as long as  is necessary to prepare the timber
 for subsequent  Impregnation of preservative.
     While originally intended for use with straight coal-tar creosote,
 the Boulton process also can be employed with creosote mixtures or any
 preservative oils that will  not foam or cause problems during the
 conditioning period.   The Boulton  process is  entirely  unsuitable for
 waterborne preservatives, however,  because  the  water in the  solution would
 evaporate even more readily  than that  in the  wood.7
     The chief advantages of the Boulton process  are:   (1) milder
 temperatures are used  (as compared  to  the steaming process)  with minimum
effect  on the strength  and on the physical condition of the  wood,' (2)  the
moisture content of the wood  never  increases, and (3) a greater  moisture
reduction can be obtained than  is possible with the steaming process.2
     The chief disadvantages  of the Boulton process are that (1)  it  1s
suitable for oil-based  preservatives only, (2)  1t often costs more than
                                   18

-------
 air-seasoning,  (3)  It  heats the wood more  slowly than  steaming or boiling
 at high temperatures without vacuum, and (4)  It  usually  requires  a
 considerably  longer time  than the steaming-and-vacuum  process.
 3.2.3  Vapor-Drying Process
     During the vapor-drying process, the  wood in the  treating cylinder  is
 exposed to hot vapors  produced by boiling  an  organic solvent,  such as
 xylene; the vapors  are then condensed.  As condensation  takes  place, the
 latent heat of the  solvent  1s given up and the moisture  vaporizes.  The
 resulting mixed vapors of water and the solvent  are then passed through  a
 condenser so  the water can  be separated and drained away and the  solvent
 recovered and reused.  The  best results are obtained with solvents that
 have a boiling range of 280"  to 320"F.3
 3.3  PRESSURE PROCESSES
     Most of the wood-preserving methods in use may be classified  roughly
 as either pressure  processes,  in which the wood  1s placed in a treating
 cylinder or retort  and Impregnated with preservative under considerable
 force, or nonpressure processes,  which are carried out without the use of
 induced pressure.    In nonpressure processes, the preservative  1s applied
 to the wood by brushing or  spraying or by dipping, soaking, or steeping
 the wood 1n the preservative.   However,  the majority of wood treated
 annually 1s impregnated by pressure methods in closed cylinders.7
 Therefore, only pressure processes are discussed  1n the following
 sections.
     Pressure processes differ  in details,  but the general  principle is
 the same.   The treatment 1s carried out  1n  steel  cylinders  or retorts,
most within the limits  of 6 to 9 feet  in diameter and up  to 150 feet  or
more in length and are  built to withstand working pressures up  to
250 ps1.7   The wood 1s  loaded on special  tram  cars and  run  into the
retort, which is then closed and filled  with preservative.   Applied
pressure forces preservative Into the wood  until  the desired amount has
been absorbed.  Three processes, the full-cell, modified  full-cell, and
empty-cell,  are 1n common use.
                                    19

-------
 3.3.1   Full-Cell  Process
     The full-cell  (Bethel) process is used when the retention of a
 maximum quantity  of preservative is desired.  Timbers typically are
 treated full-cell with creosote when protection against marine borers is
 required.  Waterborne preservatives are generally applied by  the full-cell
 process, and control over preservative retention is obtained  by regulating
 the concentration of the treating solution.3
     Steps in the full-cell process are listed below:
     1.  The charge of wood is sealed in the treating cylinder,  and a
 preliminary vacuum  is applied for 0.5 hour or more to remove  the air from
 the cylinder and  as much as possible from the wood.
     2.  The preservative, at ambient or elevated temperature depending  on
 the system, is admitted to the cylinder without breaking the  vacuum.
     3.  After the  cylinder is filled, pressure is applied until  the wood
 will take no more preservative or until  the required retention of
 preservative is obtained.
     4.  When the pressure period is completed,  the preservative  is
 withdrawn from the  cylinder.
     5.  A short final  vacuum may be applied to  minimize dripping of
 preservative from the charge.
     When the wood  is steamed  before treatment,  the preservative is
 admitted at the end of  the vacuum period  that follows  steaming.  When the
 timber has received preliminary conditioning by  the Boulton  or boiling-
 under-vacuum process, the cylinder can be filled and the  pressure applied
 as soon as the conditioning period  is completed.3
 3.3.2  Modified Full-Cell  Process
     The modified full-cell process  is basically the same as  the full-cell
process except for the  amount  of  initial vacuum.  The modified full-cell
process uses  lower levels  of vacuum; the actual  amount 1s determined by
the wood species  and the  final  retention desired.  This process is used
only on material  2 inches  or less  in thickness.3
                                   20

-------
 3.3.3   Empty-Cell  Process
     The objective of  empty-cell  treatment is to obtain deep penetration
 with a relatively  low  net  retention of preservative.   For treatment with
 oil preservatives, the empty-cell  process should always be used if it will
 provide the  desired  retention.  Two empty-cell  processes,  the Rueping and
 the Lowry, are commonly employed;  both use the  expansive force of
 compressed air to  drive out part  of the preservative  absorbed during the
 pressure period.
     3.3.3.1  Ruepinq  Process.  The Rueping empty-cell  process has been
 widely used  for many years in both Europe and the United States.   The
 following general  procedure is employed:
     1.   A1r under pressure is forced  into the  treating cylinder,  which
 contains the charge  of wood.  The  air  penetrates  some species  easily,
 requiring but  a few  minutes' application  of  pressure.   In  the  treatment  of
 the more resistant species, common practice  is  to maintain air pressure
 from % to 1  hour before admitting  the  preservative, but  the necessity for
 long air-pressure periods does not seem fully established.  The air
 pressures employed generally range between 25 and  100 ps1 depending on the
 net retention  of preservative desired  and the resistance of the wood.
     2.   After the period of preliminary air pressure, preservative is
 forced  Into  the cylinder.  As the  preservative  1s pumped 1n, the air
 escapes  from the treating cylinder into an equalizing or Rueping tank at a
 rate that keeps the pressure constant within the cylinder.  When the
 treating  cylinder is filled with preservative, the treating pressure is
 raised above that of the initial air and is maintained until the wood will
 take no more preservative,  or until enough has been absorbed to leave the
 required  retention of preservative 1n the wood after the treatment.
     3.  At the end of the  pressure period, the preservative 1s drained
from the cylinder,  and surplus preservative is removed from the wood with
a final vacuum.  The amount recovered may be from 20 to  60 percent of the
gross amount Injected.3
     3.3.3.2  Lowry Process.   The  Lowry process  is often called the empty-
cell  process without Initial  air pressure.  Preservative is admitted to
the cylinder without either an Initial  air pressure or a vacuum, and the
air originally in  the wood  at  atmospheric pressure 1s  Imprisoned during
                                    21

-------
the filling period.  After the cylinder is filled with the preservative,
pressure is applied, and the remainder of the treatment 1s the same as
described for the Rueping treatment.3
     The Lowry process has the advantage that equipment for the full-cell
process can be used without'other accessories;  the Rueping process usually
requires additional equipment, such  as an air compressor and an extra
cylinder or Rueping tank for the preservative,  or a suitable pump to force
the preservative into the cylinder against the  air pressure.  Both
processes, however, are widely and successfully used.3

                      4.0  AIR EMISSIONS AND CONTROLS

     The operation of equipment used for treating wood with  creosote
solutions results in the emission of odor-causing air  contaminants  and
possible air  toxics.  For the purposes of  this  study,  it  was not  possible
to quantify emissions.  However, a Toxic Chemical Release Inventory
Reporting Form  (EPA Form R) completed by Koppers1 Salem,  Virginia,
facility in compliance with Section 313 of Title III of the  Superfund
Amendments and  Reauthorization Act of 1986 was  obtained and  is  presented
in Appendix A.  Koppers reported emissions of the following  in  1987:
                                       Annual emissions,  Ib/yr
                                       Fugitive          Stack
     Biphenyl                              280             10
     Dibenzofuran                          640             10
     Anthracene                           730               4
     Naphthalene                         5,900            480
The primary sources of emissions and odor  have  been Identified  as:
     1.  The  treated charge immediately after removal  from the  retort;
     2.  The  vacuum system; and
     3.  Displaced air from working tank blow backs;
Information found in the literature and observations made during plant
visits (see Appendix B) aided in identifying the above  sources.
4.1  TREATED  CHARGE
     One source reports that emissions from treated wood immediately after
removal from  the retort usually exceed 60 percent opacity beyond the
opaque water  vapor breakoff point and continue to exceed 40 percent
opacity for up to 20 minutes.    Heat from the treated charge causes some
of the lower boiling organic compounds to volatilize as aerosols,  forming
a dense white emission plume.   Emissions  of 60 percent  opacity or  more
beyond the opaque steam plume  from the open end of  the  retort continue
only during the few minutes  it takes  to  remove the  treated wood and
recharge the retort.8   However,  during a  recent visit to one  facility it
was noted that a charge pulled 14 hours earlier was  still  showing  evidence
of visible emissions and odor  (see  Appendix B - Koppers trip  report).
                                    23

-------
     Several techniques for controlling fugitive emission losses from
treated charges have been suggested with varying degrees of success.  One
approach is to construct a ventilation hood or building to collect organic
vapors coming off the charge.  The hood would need to cover the entire end
of the retort, a section of track and switches, and a complete tram or
trams.  Such a structure, perhaps exceeding 150 feet in length, would
require enormous gas exhaust rates, and the associated emission control
devices would also be very large.  Such hooding and ventilation systems
could be economically unfeasible for the retrofit of existing uncontrolled
plants.8
     Low boiling point organics may be controlled by reducing the
temperature of the freshly treated wood.  To drop the temperature of the
wood, heat must be conducted and/or convected out of the wood.  Fourier's
equation provides the basic relationship that describes steady-state heat
conduction.
where:
         q = heat conduction in x direction, Btu/h
         A - cross-sectional area normal  to heat flow,  ft2
     dt/dx = temperature gradient in x direction, °F/ft
         k = thermal conductivity of conducting medium, Btu/h«ft«°F

The thermal conductivities of water and air at  32°F are reported as 0.343
and 0.0140, respectively.9  Thermal conductivity is moderately dependent
on temperature.  Nonetheless, the thermal  conductivity  of water is between
20 and 25 times greater than the thermal  conductivity of air in the
temperature range of 32° to 200°F.  Thus,  water will  cool the wood ties
faster than air.
     Two processes aimed at cooling the freshly treated ties using water
have been demonstrated.  In the first, a  manifold containing spray nozzles
is mounted a few centimeters from the open end  of the retort.  The nozzles
are positioned to blanket the entire opening and emerging charge with
water sprayed at about 300 gallons/minute  as the charge is slowly pulled
                                    24

-------
 from the retort (no faster than 17 feet per minute).8  In theory, the
 water spray will  cool  the  ties  and scrub and condense the escaping
 vapors.   In reality, this  method has  enjoyed limited success.   While
 controlling some  of the  initial  vapors, the water spray actually does very
 little to cool  the  ties.   The ties that are stacked in the center are not
 subjected to the  spray so  the charge  as a whole is not significantly
 cooled.
      The second process  involves using  water to quench the ties  while
 still  in the retort.   Following  the final vacuum and before the  retort
 door is  opened  to remove the treated  ties,  the  retort is  filled  with water
 to quench the ties.  The water  is  then  emptied  and the ties are  removed.
 This water quench cycle may have to be  repeated or be designed with  a
 circulating water system if the  void  volume  in  the retort is not great
 enough to allow sufficient cooling water  into the  retort  to cool  the
 ties.  This system  has been demonstrated  to  be  successful  in controlling
 emissions from  a  plant treating  approximately 430  air-dried ties  per
 charge with a void volume of approximately  15,000  gallons  (see
 Appendix  B - Jennison-Wright trip  report).
     One  obvious  drawback to these two methods  is  that the  contaminant 1s
 merely transferred from the air  to the water, resulting 1n the need  for
 treatment of an additional effluent stream.  Facilities using these
 methods to cool the ties will recycle the water and remove the insolubles
 periodically.  A cooling system or a large-capacity water system will  be
 needed to keep cooling water temperatures low to maintain the
 effectiveness of the quenching system.
 4.2  VACUUM SYSTEM
     During  the Boulton process  and the final vacuum applied during the
 Rueping process, volatile organics are evaporating from the creosote
 solution  and exiting the  retort  through the vacuum system.  In the two
 plants visited,  one plant uses a reciprocating vacuum pump while the other
uses a steam jet ejector  to induce a vacuum of 22 to 24 inches  of mercury
on the retort.  Both plants have a single-pass,  water-cooled condenser in
 line between the vacuum source and the retort to condense  the vapors.
     Koppers uses  two steam jet  ejectors to  Induce the vacuum on  the
retorts.   A 4-inch steam  jet is  used to  draw the system pressure  down to
                                    25

-------
between 22 and 24 Inches of mercury, usually taking  between  1  and
2 hours.  Ideally, once the vacuum has been obtained,  the  operator will
switch over to a 2-Inch steam jet to maintain the vacuum for the remainder
of the cycle to save energy.  However, during periods  of high  steam demand
there may not be enough steam available from the plant's boiler to
maintain a 24-Inches (mercury) vacuum using the 2-inch steam jet.
Therefore, the 4-inch steam jet may remain on during the entire vacuum
cycle if the steam demand (I.e., heat for retorts, working tanks,
buildings, etc.) for the rest of the plant is high.
     Odors emanating from the steam jet suggest that the single-pass,
water-cooled condenser may not be capable of condensing all  of the
organics, allowing them to become entrained in the steam jet.  There are
several possible solutions to eliminate this odor.  The first  is to
install a larger condenser capable of reducing the organic content in the
vapor further.  Secondly, the vacuum system can be modified  to include two
steam jet ejectors in series with a barometric (direct contact)
intercondenser between them.  In this type of ejector  system, the
barometric intercondensers condense the oily vapors entrained in the steam
and flush them out with the intercondensed water.10  A third option would
be to replace the steam jet ejectors with a vacuum pump and route  the
exhaust vapors to an activated carbon adsorption system or to an
afterburner.  Both are extremely efficient methods to remove organics from
the exhaust gas.
     The steam jet ejectors should not be used with the latter two control
options.  Water may preferentially adsorb onto carbon in the activated
carbon system and impede the diffusion of organics  into the pore  spaces.
The steam jets also will  generate a larger volume of  gas to be  treated by
either method and lower the average Btu  value of the  steam, which  is a
factor to consider if an afterburner is  used.
     Incineration of air contaminants  in an afterburner is  a proven method
for controlling emissions during  the operation of the vacuum cycle.8  The
volume of the contaminated gaseous  effluent varies  from about 300 to
1,200 scfm.   Precautions  should be  taken  to keep gas  velocities well  above
flame propagation velocities to prevent  flashback.  This can  be
accomplished by narrowing  the  throat diameter leading into  the
                                    26

-------
afterburner.   The afterburner should  be  designed for an exit  temperature
of  1500°F  and a retention time of  0.3 seconds or more in the  combustion
zone.8  Source tests  have shown afterburner efficiencies of 99  percent
when operated at 1400°F exit  temperature.8
     Studies  have shown that  afterburner operating costs can  be reduced by
recovering the heat from the  afterburner exhaust gases.   A shell-and-tube
heat exchanger can be installed at the outlet from the afterburner to heat
boiler feed water or  to supplement the steam producing facilities of the
wood-treating plant.
4.3  WORKING  TANK BLOW BACKS
     A working tank blow back  event occurs  when,  at the  end of  a treatment
cycle, the creosote solution  is sent  back to the  work  tanks.  The air
displaced  by  the filling of the work  tanks  is at  equilibrium with the
preservative  in the tank.  If  30,000  gallons of preservative fill each
retort, as  is the case with Koppers,  then approximately  4,000 cubic feet
of air are  displaced  when the  solution is sent back to the work tanks.
Each of the two plants visited  use a  water  scrubber system to control blow
back vapors.   The vapors are bubbled  through water and/or brought into
contact with  a water  spray and  vented to the atmosphere.  The effective-
ness of these systems  as scrubbers would be  expected to approach zero if
the water  is  allowed  to reach saturation and 1s not changed periodically.
     Another  option for controlling blow back  vapors is to incinerate them
in an afterburner.  It  is  worth  noting that  in the  Koppers and Jennison-
Wright treatment  process,  a vacuum cycle always follows a blow back to the
work tanks.   As discussed  in the previous section regarding the control  of
vacuum system vapors, an afterburner  is a proven method of controlling
emissions during  the operation of the vacuum system.
     It should be possible to control  blow back vapors by firing the
afterburner 15 minutes  earlier  (the approximate time needed to empty  the
retort) and ducting the blow back vapors  to the afterburner.   Immediately
after the blow back,  the vacuum system is cut on and the exhaust vapors
are ducted to the afterburner.  During the Boultonizing cycle, the
afterburner will be controlling vapors from the vacuum system  and from the
blow back simultaneously.
                                    27

-------
     During blow backs, Koppers Indicated that 1t uses pressure built up
1n the retort to force the preservative back  up through the bottom of the
work tank.  Problems arise when an operator does not closely monitor how
much preservative 1s being blown back and begins to blow air up through
the working tanks.  Air bubbled up through the work tanks picks up
volatile material and carries  it out the vent.  This scenario can be
prevented by emptying the retorts using a centrifugal  pump.10
                                   28

-------
                              5.0  CONCLUSIONS

      The  operation  of equipment  used  for treating wood  with  creosote
 solutions results in the emission  of  odor-causing air contaminants  and
 possible  air toxics.  Information  found in the literature  and  observations
 made  during  plant visits suggest that there are three primary  sources  of
 air emissions at creosote wood treatment plants.   Table 8  lists  these
 emission  sources and the available techniques  demonstrated to  control
 them.
      At this time,  no reliable quantitative estimates of emissions  from
 these sources or possible emission reductions  from the  respective control
 devices have been made.  Koppers has  quantified and reported emissions of
 biphenyl,  dibenzofuran, anthracene, and naphthalene in  its 1987  Toxic
 Chemical  Release Inventory Reporting  Form (Appendix A)  totaling  over
 8,000 pounds per year.  Approximately 80 percent  of the  emissions were
 reported  as  naphthalene.
     As a  result of the plant visits  to Koppers and Jennison-Wright,
 information  is available to compare and contrast  the  two facilities  and
 make qualitative assessments of emissions.   Table 9 presents a comparison
 and contrast of the two plants and the methods  and  practices used to treat
 their respective charges.  In order to establish  a  baseline for
 comparison,  it is worth noting that both  plants are treating railroad  ties
 for the same customer (Norfolk & Southern)  to the same target retention of
 preservative (about 8 lb/ft3), and using  the same 60/40 creosote/coal  tar
 preservative solution.   However, the  plants differ  in several respects.
 The most noteworthy of these is that  Koppers treats mostly unseasoned  ties
 and Jennison-Wright treats  only air-dried (seasoned) ties.   As a result,
 Koppers has  a much longer treatment cycle because it must Boultonize the
 ties to remove moisture  from the sapwood of the charge.
     The Boulton cycle  used by Koppers to condition unseasoned ties may
 significantly increase  the  odor or air toxic release over that of a
facility treating seasoned  ties not requiring moisture removal.  The
 following two process conditions clearly support this  suggestion.  First,
the Koppers process  has  a treatment time of approximately 24  hours,  which
 is two to three times longer than the time required at Jennison-Wright.

-------
The extended treatment time is the result of the addition of the 16 to
IS hour Boulton cycle.  The vacuum system, identified as a major emission
source, runs continuously during the Boulton cycle.  The extended
operation of this emission source creates a greater potential for the
release of odor and air toxics.
     Secondly, the Boulton cycle results in an additional blow back of
preservative to the work tanks.  This Increases, perhaps doubles, the
potential for odor and air toxics to be emitted.  As presented in Table 9,
although Koppers has twice the number of blow backs and approximately
twice the void volume in the retort (measure of how much preservative is
transferred to and from the working tanks) as Jennison-Wright, Koppers'
20,000 gallon water scrubber system is 25 times smaller than that of
Jennison-Wright.  A qualitative assessment suggests that a substantially
higher potential for emissions during blow back periods exists at Koppers.
     A final comparison from Table 9 shows that the volume of wood per
volume of void space is approximately the same for the two plants.
Koppers has slightly less void space per cubic foot of wood in and around
the charge (about 7 percent less).  This suggests that Koppers may be able
to quench and cool the ties in a manner similar to Jennison-Wright.
However, the Koppers charge did appear hotter than the Jennison-Wright
charge (before quenching) and may require more cooling water to
appreciably lower the temperature of the charge.

  IV.  Process Description

      The Koppers facility, located in Salem, Virginia,  is a wood
preserving plant that treats 20 to 25 percent seasoned and 75 to
80 percent unseasoned (green or undried) cross ties and  switch ties  for
the Norfolk & Southern Railroad.  The plant treats approximately
3,000 ties per day and operates 24 hours per day, 5 days per week.   The
plant has been in operation since 1955.  A process flow  diagram for  the
Koppers wood treatment process is presented in Figure 1  and photographs
from the plant visit are attached.

      A.  Wood Treatment Process

      The Koppers plant operates three steel treatment cylinders or
retorts, each 8 feet in diameter and 140 feet long.  The retrofits operate
on a staggered schedule.  Approximately 1,000 ties (approximately
3,200 ft  of wood) are treated per charge in each retort.  The charge  is
rolled into the retorts on 16 small raiTears each of which holds
approximately 70 ties with small wood spacers between each tie.  After the
charge is loaded and the door is closed, the retort is filled with about
20,000 gallons of a 60/40 creosote/coal tar mixture (just enough to  cover
the ties) from one of four 50,000-gallon working tanks.

      The creosote and coal tar are mixed off site by the supplier.   The
plant is designed to use creosote solutions containing no more than
7 percent naphthalene.  Excessive quantities of naphthalene in the
preservative can precipitate and clog various transfer pipes.  Koppers
specifies to their preservative supplier that the creosote solution
contain 7 percent naphthalene.

      After the retort is filled and sealed, the contents are heated to
between 190° and 200°F and 24 inches of mercury vacuum is pulled on the
system for 16 to 18 hours (Boultonlzing).   This lowers the moisture
content of the unseasoned wood  by removing  water from the sapwood and
replacing it with the creosote  oil.   Water  and vapors are carried out
under induced vacuum to a condenser;  the condensate is sent to an effluent
treatment system.  At the end of the Boultoning cycle, the creosote
solution is pumped from the retort back to  the work tanks.   The  vacuum is
maintained in the retort for an additional  one-half hour  to reduce further
the moisture content of the wood.   By monitoring how much water  has
condensed in the condenser, the operator knows when the optimum  moisture
content has been reached.   At that point, 50 psi  pressure is  applied for
30 minutes to an hour to force  the residual  creosote  solution into the
wood.   Next, 30,000 gallons of  the creosote  solution  from the working
tanks  is reintroduced into the  retort,  heated  to  between  190°  and  200°F,
and pressurized  to between 160  and 170  psig  for  2 to  4 hours  depending on
the species of wood (Rueping process).   The  creosote  used in  the  Rueping
process must contain less  than  3  percent water in order for proper
treatment to occur.   The Boultonizing cycle  dehydrates the  creosote
solution in addition to  the charge that  is being  treated.

-------
      The Rueping process compresses the air in the interior wood  cells
and forces the preservative into the wood.  The pressure  is maintained
until the target preservative retention level is reached.  Koppers1  target
retention as specified by the Nolfolk & Southern Railroad  is 7 to  8  pounds
of preservative per cubic foot of wood with 65 percent of  the annual  rings
in the tie being treated for red oak.  When this is accomplished,  the
pressure is relieved and the retort is emptied of preservative.  The
expanding air in the interior wood cells expels the preservative leaving
an empty, treated cell (i.e., the creosote adheres to the  cell walls).
The vacuum (22 to 24 inches of mercury) is then reapplied  for about  1 hour
to extract residual creosote that tends to drip upon removal of the
charge, thus producing a cleaner product and allowing recovery and recycle
of excess preservative (which currently costs $0.80 to $1.40 per
gallon).  A diagram depicting the pressure fluctuations during a treatment
cycle is shown in Figure 2.

      Following the final vacuum, the retort door is opened, the rail
bridge is lowered, and the charge is pulled from the retort by a small
locomotive.  During the site visit, a small amount (approximately
5 gallons) of creosote spilled from the retort into the sump below when
the retort door was opened.

      B.  Effluent Treatment System

      Koppers is in the process of closing its wastewater treatment
lagoons and is installing an aboveground effluent treatment system.   The
effluent treatment system will  handle condensate exiting the condenser and
the scrubber water used to treat the working tank vapors.   These effluents
are initially fed into one of two 28,000-gallon naphthalene recovery
tanks, which are kept at about 100°F.   The naphthalene (mp = 176°F)
contained in the effluent crystallizes and falls to the bottom of the
tanks where it is heated to melting and drained off the tank bottom.  The
recovered naphthalene is returned to the working tanks for reuse.   The
aqueous fraction of the effluent from the naphthalene  recovery system is
sent to one of two 150,000-gallon effluent holding  tanks.   The effluent is
then sent to an activated sludge tank  for biological removal  of other
dissolved organics.   From there it is  pumped to  an  oil/water separator
that currently serves as a holding basin.   After testing  for phenol and
other organic compounds,  the effluent  is  sent  to a  7 acre  spray irrigation
field.  A soon-to-be-constructed city  sewer line will  be the  ultimate
disposal route for the effluent in the holding  basin.

  V.  Odor Sources

      The three predominant sources  of odor (and  potential  air  toxics)
identified at the Koppers facility are:

      1.  Treated wood  exiting  the retorts;
      2.  Steam jet  injectors;  and
      3.  Blow-back  vapors  from  work tanks.

               Pressure fluctuations in  the  retort during the treatment cycle at
               Koppers1 Salem, Virginia  wood treatment plant.

-------
Visible emissions were observed from a charge that had been pulled  out
14  hours prior to our visit and was being unloaded into another  railcar.
During the visit, a freshly treated charge was pulled from the center
retort.  As the retort door opened, a dense, white plume of gas  exited the
treatment chamber and continued to be emitted as the charge was  being
pulled from the retort.  The charge, approximately 130 feet long, fumed
and emitted a white vapor cloud and a strong creosote odor.  There  was a
noticeable odor of creosote coming from the stock yard where the treated
ties are stored.

      The steam jet injectors used to produce the vacuum in the  retorts
are also a source of odors.  To induce the vaccum on the retorts Koppers
uses two stream jet injectors.  A 4-inch steam jet is used to draw  the
system pressure down to between 22 and 24 inches of mercury.  This  usually
takes between 1 and 2 hours.  Ideally, once the vacuum has been  obtained,
the operator will switch over to a 2-inch steam jet to maintain  the vacuum
for the remainder of the cycle to save energy.  However, during  periods of
high steam demand there may not be enough steam available from the  power
plant's boiler to maintain a 24 inch of mercury vacuum using the 2-inch
steam jet.  Therefore, the 4-inch steam jet may remain on the entire
vacuum cycle if the steam demand for the rest of the plant is high  (i.e.,
heat for retorts, working tanks, buildings, etc.).   The single pass water
cooled condenser, operating between the retort and  the steam jet, may  not
be  capable of removing all of the organics, which become entrained  in  the
steam jet.  A large, dense steam plume was emitted  from the 4-inch
Injector, and a strong creosote odor was noted when the wind shifted.   The
2-inch injector emitted significantly less visible  emissions than did  the
4-inch injector.

      Working losses from the four creosote working tanks  could  be  a
significant contributor to the odor problem.   A working tank blow back
event occurs when the creosote is sent back to the  work tanks.   The air
displaced by the filling of the work tanks is at equilibrium with the
preservative in the tanks.  The 30,000 gallons of preservative  used to
fill a retort will displace approximately 4,000 cubic feet  of air when  the
solution is sent back to the work tanks.   This event  will  occur twice
during the Koppers treatment cycle.   It takes approximately 15  minutes to
empty the retort of preservative.   The work tanks are equipped  with a
common scrubber consisting of a horizontally  mounted  20,000-gallon tank
half full of water with a spray system inside.   When  a blow back  occurs
the  displaced vapors from the work tanks  enter the  top of the scrubber and
contact the spray.  The exhaust gas  is  then vented  to the atmosphere.   Its
effectiveness as a scrubber would  be expected to  approach zero  if the
water is not changed periodically  and  allowed to  reach  saturation.   At
that point it could only serve as  a  condenser.  We  did  not  witness  a blow
back event during our visit.   Currently the plant has no formal procedures
in place for periodically changing or  regenerating  the  scrubber water.
The plant manager stated that no procedures are  in  place because  the
scrubber has been very effective at  controlling blowback odors.   He  states
that monitoring the water level  alone  has maintained  the effectiveness of

-------
the scrubber.  If it becomes necessary to change the water or empty the
scrubber, the water will be sent to the effluent treatment system.

  IV.   Process Description

       The  Jennison-Wright facility, located in Toledo, Ohio, is a wood
 preserving plant that treats air dried cross ties and floor block
 material.   In the tie treating operation, approximately 430 ties are
 treated  per charge with between two and three charges treated per day.
 The plant  has been in operation since 1905 and operates 20 hours per day,
 5 days per week.  A process flow diagram for the Jennison-Wright wood
 treatment  process is presented in Figure 1.

       A.   Wood Treatment Process

       The  Jennison-Wright plant operates three treatment cylinders or
 retorts, each 6 feet in diameter.  Cylinders 1 and 2 (see Figure 1) are
 about  80 years old and are used to treat floor blocks.  Each are a
 100 feet long.  The floor blocks are loaded into cages and rolled into the
 cylinders  on railcars.  The creosote solution is introduced into the
 cylinders  from a dedicated working tank.  The treatment cycle is short
 (about 2 hours) and is designed only to coat the outside of the blocks
 with preservative.

       The  focus on our visit was to characterize the treatment process and
 odor control techniques associated with cylinder 3, a new, 120-foot-long
 cylinder installed in 1987 to treat railroad ties.  The new cylinder was
 installed  to replace an old, worn out cylinder.   The purpose of the
 installation was to improve production schedules and quality so the
 facility can function in a more cost-effective,  environmentally acceptable
 manner and, thus, enhance the company's competitive position.   Because
 cylinder 3  is a new source, the State of Ohio Environmental  Protection
 Agency required Jennison-Wright to file a permit to assure compliance with
 current State air quality requirements (permit attached).   The permit
 specifies  that all new sources must employ best  available  technology (BAT)
 for control of air emissions.

       Jennison-Wright treats railroad ties to varying preservative
 retention  specifications.   Ties treated for Jennison-Wright  stock are
 treated to  a retention level  between 4 and 5 pounds of preservative per
 cubic  foot.  The Grand Truck railroad specifies  product retention of
 7 pounds per cubic foot,  and the Norfolk and Southern railroad requires
 retention of 8 pounds per cubic foot and sterilization of  the  ties in the
 treatment cycle.   The process used to treat ties  for the Norfolk and
 Southern railroad was observed during our visit.   Jennison-Wright
 considers annual  production information to be confidential.

      Approximately 430 ties  (1,148 3  of wood) are treated per charge in
 cylinder 3 using  the  Reuping  process,  which compresses  the air in interior
wood cells and forces preservative into the wood.   The  charge  is rolled
 into the retorts  on 14 small  rail cars  each  of  which  holds  approximately
 30 ties.   After the charge is loaded and the door  is  closed, the retort is
 filled with about 17,000  gallons  of a  60/40 creosote/coal  tar  mixture from
one of three,  50,000-gallon working tanks.

      After the retort is filled, the contents are heated to 205°F  and  the
pressure in the retort is raised to about 30 psig for approximately
4 hours.  The initial pressure requirement is a function of how readily
the charge accepts the creosote and obtains its target retention of 7 to
8 pounds of preservative per cubic foot of wood.  By holding the
temperture of the ties at 205°F for 4 hours, the ties are sterilized to
prevent decay that destroys the wood from within.  Following the
sterilization cycle, the pressure is stepped up approximately 10 psig
every 15 minutes until the pressure in the retort reaches 200 psig.  The
pressure (200 psig) is maintained until the target preservative retention
level is reached.  Again, the rate of increase in system pressure is
dependent on the type of wood being treated and how readily the wood cells
accept the creosote.

      When the target retention level is reached, the pressure is
relieved, and the retort is emptied of preservative.   A moderate pressure
of about 10 psig is maintained in the retort to aid the pump in
transferring the creosote back to the work tanks.  The expanding air in
the interior wood cells expels the preservative leaving an empty, treated
cell.  A vacuum (25 inches of mercury) is then applied for 1 hour to
extract residual creosote that tends to drip from the charge, thus
producing a cleaner product and allowing the recovery and recycle of
excess preservative.  A diagram depicting the pressure fluctuations during
a treatment cycle is shown in Figure 2.

      Following the vacuum cycle, 17,000 gallons of water are pumped into
the retort to quench the treated ties, lower their temperature,  and reduce
fugitive emissions of lower boiling point organics typically associated
with odor.  The quench water is recirculated in a closed loop system
through a 500,000-gallon fixed-roof tank that is half full  of water.  Blow
back vapors generated from the displacement of air in the work tanks are
introduced into the vapor space in the tank.

      A cone-shaped water scrubber is mounted on top  of the tank.   The
diameters of the scrubber at the top and bottom are approximately 5 feet
and 15 inches, respectively, and it is approximately  6 feet in height.  A
manifold encircles the scrubber midway up the cone and supplies  eight
spray nozzles inside the scrubber with water (24 gallons per minute) taken
from inside the tank.   The spray scrubs and condenses vapors and carries
the condensate back down into the tank.   We observed  the scrubber  system
in operation during a blow back of creosote to the work  tanks.   No visible
emissions were observed from the scrubber during the  blow back.  We were
not in a position to detect whether there were odors  coming  from the
scrubber.

      For the purposes of our visit and  to illustrate the effectiveness  of
the water quench system,  Jennison-Wright personnel  opened the  retort door
and allowed us to view the charge in the retort after the pressure cycle
(before the vacuum was applied)  and after the  vacuum  cycle  (before the
water quench cycle).   Following the pressure cycle, a white  vapor  cloud
exited the retort as  the  door was  opened.   Along  the  end  of  the  charge,
excess preservative and expanding  air  could be seen exiting  the  hot  ties.

                 Jennison-Wright's Toledo, Ohio wood treatment plant.

The ties appeared wet with preservative as excess preservative dripped and
fumed from the charge.  After the vacuum cycle was completed, the door was
once again opened.  The charge still  appeared hot, and a white plume of
vapor exited the retort although not  as profusely as was observed before
the vacuum cycle.  The charge appeared dry with little or no excess
preservative dripping from the charge.  After the water quench cycle the
treated charge was removed.   The ties appeared to be substantially cooler,
and almost no visible emissions were  observed.  We did not detect a strong
odor of creosote from the freshly treated charge.
