INTRODUCTION
Background
The Mobil Oil Corporation operates an integrated petroleum refinery
o
at this location with a rated capacity of 20,700 m (130,000 bbl) of
crude oil per day. Major products from this refinery include refinery
fuel gas, LPG, aviation gasoline, motor gasoline, jet fuels, distillates,
fuel oil, weed oil, sulfur and coke. This refinery was modernized in
1967, making it a new refinery.
The Mobil Torrance refinery employs about 600 people. The facility
operates three 8-hour shifts, 7 days per week, year around.
On November 6-7, 1975, a process inspection was conducted at this
facility by NEIC personnel. The inspection was preceded by a letter to
the Company on September 8, 1975, announcing NEIC's intention to inspect
the facility and requesting substantial amounts of process information
[Appendix A], Subsequent to the inspection, Mobil personnel transmitted
the requested information via mail.
During the inspection, an examination was made of the manufacturing
equipment, potential air pollution sources, and air pollution control
equipment. The purpose of this inspection was to evaluate the degree of
compliance of this facility with the requirements of the Federally
approved State Implementation Plan as required by Section 110 of the
Clean Air Act, as amended.

Company personnel were highly cooperative throughout this inspection.
They supplied all EPA requested information during the inspection inter-
view or by subsequent letter.

PROCESS DESCRIPTION
The Mobil Torrance Refinery processes California crude oil when
it is available but does process some imported crude when necessary.
Crude oil is delivered to the refinery via pipeline or tank ships. Primary
products from this refinery include LPG, gasoline, jet fuel, diesel fuel,
fuel oil, petroleum coke and sulfur.
Major processes used at this refinery include crude desalting,
atmospheric distillation, vacuum distillation, delayed coking, catalytic
cracking, hydrocracking, catalytic reforming, hydrotreating,
alkylation, hydrogenation, hydrogen production, and sulfur recovery. A
simplified process block flow diagram for the facility is shown in Figure 1.
POTENTIAL SOURCES OF AIR POLLUTION EMISSIONS AND RELATED CONTROL EQUIPMENT
Although the Mobil Refinery is a complex facility, there are
relatively few large discrete potential sources of air pollutant emissions.
With the exception of the fluid catalytic cracking (FCC) unit, the major
unit processes at the refinery are closed systems and release of materials
to the atmosphere is discouraged because such releases would result in
loss of product. The process heaters attendant to these units constitute
the main emission sources. There are also a myriad of relatively small

potential sources of emissions related to the very operation of the
refinery. Such sources include leaks from valve and pump seals, pipe
flanges, etc., evaporative losses from storage tanks, process wastewater
drains, etc. Potential sources of emissions and their related control
equipment are discussed herein.
Process Heaters and Boilers
There are 41 process heaters and boilers ranging in size from 1.3 X
109 to 1.1 X 1011 cal (5 X 106 to 450 X 106 Btu)/hr. A complete listing
of these units is presented in Appendix C. Four of the process heaters
are currently idle.
The majority of these units utilize refinery fuel gas as fuel. The
remainder can be fueled with either refinery gas or fuel oil.
With the exception of the carbon monoxide (CO) boiler at the FCC
unit which will be discussed later, none of the process heaters or
boilers have been equipped with emission control devices or monitors.
The main refinery boiler (75F-1) is equipped with an Environmental Data
Corp. DIGA-13 Opacity, N0X, and S02 monitor.
Sulfur oxide emissions from these units are controlled by limiting
the sulfur content of the fuels burned. Refinery gas must be desulfurized
3 3
to less than 1.1 gm/m (50 grains/100 ft ) of sulfur compounds. Fuel
oil used in stationary fuel burning equipment is produced in the refinery
from low sulfur crude. Its sulfur content is less than 0.5% by weight.
The fuel gas data [Appendix D] indicates that the fuel gas used at Mobil
3 3
contains 0.2 gm/m (8 grains/100 ft ) of sulfur and the sulfur content of
the fuel oil is 0.37% wt.,
-------
6
Internal Combustion Engines
There are 13 active and 3 inactive Clark Super Two Cycle stationary
internal combustion engines in use at the refinery and all are used to
drive compressors. All use natural gas for fuel and have a total energy
requirement of 3.0 X 1010 cal (120 X 106 Btu)/ day. None of these
internal combustion engines have emission control equipment; however,
none would be expected for this type of equipment.
Storage Tanks
There are 162 storage tanks at this facility ranging in size from
800 to 382,000 m^ (5,000 to 2,400,000 bbl) and are used to store a wide
variety of hydrocarbon materials. Due to the volatile nature of some of
these compounds, the potential exists for substantial emissions of
hydrocarbon vapors from these tanks. Where such a potential exists, the
materials are stored in specially constructed tanks, i.e., pressure
vessels, floating roof tanks, etc-, or are stored in tanks which are
hard piped via manifold systems to a vapor recovery system.
The vapor recovery system consists of a pipe network serving 46
hydrocarbon storage tanks, various processing units (used during their
shutdown periods), two truck loading facilities, and several additional
connections at the LPG loading racks. Vacuum is maintained by a bank of
compressors which discharge into the refinery fuel gas system.
In addition, 70 of the storage vessels are floating roof tanks that
are designed to minimize hydrocarbon losses [Appendix E].
-------
7
Blowdown Systems
The majority of process units have emergency relief valves which
are connected to a manifolded header system. Should a situation arise
such that it is necessary to rapidly release quantitites of liquids and
gases from a unit, they are routed to the manifold system and ultimately
combusted in a flare.
There are six flares at this refinery, however, there are only four
operating at once. All six flares are equipped with John Zink Co.
smokeless-flare tips [Appendix F]. Each flare is monitored by a closed
circuit television and the flow to each flare is measured using an
Electronic Flow Meter, Model VLP-4S.
Most of the blowdown systems are operated only on an as-needed
basis, i.e., intermittently.
Vacuum Jets
The only vacuum jet systems in use at this facility are at the
vacuum crude distillation units. These units operate as closed systems.
Gases from the vacuum towers are compressed, scrubbed through a diethanola-
mine (DEA) absorber to remove ^S and discharged to the refinery fuel
gas system.
Fluid Catalytic Cracking Unit
Spent catalyst from the FCC unit is continuously removed from the
reactor portion and introduced through piping into the catalyst regeneration
-------
8
portion. Here the petroleum coke, tars, and other residual deposits
which form on the catalyst surface are burned off the catalyst fines.
The recovered catalyst is then recycled to the reactor. Catalyst particles
which are entrained in the exhaust gases are partially captured by a
series of cyclone separators internal to the regenerator unit. Particles
captured by these cyclones are returned to the regenerator.
The regenerator unit exhaust gases contain considerable amounts of
carbon monoxide, particulate matter, aldehydes, sulfur oxides, ammonia,
and oxides of nitrogen. In order to minimize the emissions of carbon
monoxide (CO) and to recover the fuel value of this material, the
regenerator exhaust gases are combusted in a waste heat boiler. The CO
boiler exhaust gases are then passed through a Buell electrostatic
precipitator (ESP) consisting of two parallel banks with two stages per
bank.
This Buell ESP unit requires ammonia injection, i.e., ammonia gas
is injected into the inlet gas stream to the ESP to improve the ionization
of the gas.
The CO boiler at the Mobil refinery has had numerous problems,
i.e., the heat exchanger tubes in the economizer section have developed
leaks on several occasions, thus causing the CO boiler to be shut down.
When this is done, there are emissions to the atmosphere and a violation
of Rule 71 (CO Emissions) and there are possible violations of Rules 50
(Opacity) and 54 (Particulate Matter). On January 15, 1975, Mobil was
granted an emergency variance [Appendix G] as a result of these problems.
This variance included a compliance schedule that ended on December 31,
1975. Mobil has met all dates included in the compliance schedule and
has replaced all tubes in the economizer section of the CO boilers.
-------
9
The emissions from the ESP are monitored by a Lear Seigler RM-4
Opacity Monitor. This unit has a recorder and an alarm located in the
FCC control room.
Product Loading Racks
LP gas, various grades of gasoline, diesel fuel, weed oil and
carbon black oil [Appendix H] are all shipped from the refinery via
truck or trailer. All three loading racks are incorporated into the
vapor recovery system.
At Mobil the truck and rail loading racks for LP gas use an equaliz-
ing line during loading. After the filling operation is completed the
loading hoses are back-evacuated through the vapor recovery system.
All truck loading facilities are equipped with tight neoprene seals
for the truck hatches and vapor return lines to the main vapor recovery
system. The recovery system discharges into the refinery fuel gas
system and operates as a closed system.
Wastewater Treatment Facilities
The wastewater collection system at Mobil is divided into two
systems. The first collects all sour water from the sour water strippers
and is discharged from the strippers to the county sewer at a rate of
2,200 m (576,000 gal)/day. The second system collects water from the
demineralizer, cooling tower blowdowns, desalter brine, boiler blowdown,
zeolite brine, potassium cresolate (KCR) treater, waste heat boiler
blowdown, pump and compressor jacket water, and wastewater from house-
keeping. These waters are treated in a wastewater treating system [Fig. 2]

consisting of a covered API* separator, and an enclosed gas flotation
system (gas flotation accomplished by using nitrogen). After this
treatment, the wastewater is discharged to the county sewer at a rate of
3 6
11,700 m (3.1 X 10 gal)/day. All vapors emitted from this system are
collected and incinerated in the waste treatment incinerator (discussed
later).
Sulfur Plant
There are three Claus units [Fig. 3] and two Stretford-Bevon tail
gas units [Fig. 4] at the Mobil sulfur recovery plant. Each Claus plant
is rated at 90.7 m. tons (100 tons)/day and each Stretford-Bevon unit is
rated at 9 m. tons (10 tons)/day. Current operations are only producing
sour gas sufficient to produce 110 to 140 m. tons (125 to 150 tons)/day
of sulfur; therefore, these sulfur recovery units are not running at
full capacity.
In the Claus process, hydrogen sulfide (H2S) is burned to form
sulfur dioxide (S02). The S02 and H2S react in the presence of a
catalyst to form elemental sulfur and water vapor. A typical sulfur
removal efficiency for a three-stage Claus plant, such as these, is 97%.
The Bevon process [Fig. 4] first converts all sulfur compounds
[sulfur dioxide (S02), sulfur (Sx), carbononyl sulfide (COS), and carbon
disulfide (CS2)] to H2S by reduction, hydrogenation and hydrolysis over
a catalyst.
The Stretford process then converts the H2S to elemental sulfur by
absorption in an oxidizing alkaline solution containing sodium vanadate.
The vanadium is oxidized back to the pentavalent state by blowing air,
with sodium anthraquinone disulfonate (also contained) working as an
oxidation catalyst.

Any residual sulfur leaving the Stretford absorber, in the off-gas,
is normally COS with a trace of ^S (less than 10 ppmv). At Mobil, the
off-gases from this absorber are vented to the atmosphere.
There are no monitors on these two emission sources, but the LAAPCD
has proposed that these sources be continuously monitored.
These two sources are also piped to the sulfur complex incinerator
and the off-gases from these units could be incinerated in an emergency.
Incinerators
There are two incinerators at the Mobil refinery [Appendix I]. The
wastewater treatment facility incinerator serves primarily as an odor
control device. This unit incinerates all vapors collected at the
wastewater treatment facility. There are no monitors on this incinerator.
The incinerator at the sulfur complex can be used to incinerate the
off-gases from the Bevon-Stretford units or Claus units in case of an
emergency; however, in normal operation it only handles vapors from the
sulfur storage and day tank. There is an Intertech URAS-2T S02 analyzer
that monitors the emissions from this unit.
EMISSIONS DATA
Source Test Data
NEIC personnel requested that Mobil supply copies of all source
tests conducted at the facility since 1972. The LAAPCD was requested to
do likewise. The data obtained is summarized below.
-------
15
FCC Unit Emissions. Mobil submitted a copy of the source test
conducted on the electrostatic precipitator (ESP) exhaust stack attendant
to the FCC unit. This test [Appendix J] was conducted on May 30, 1974
by Truesdail Laboratories, Inc. of Los Angeles, California. Details for
the operating conditions at the FCC stacks are presented in Appendix J.
From these data it is not possible to determine whether the test was
conducted at start-of-run conditions on the FCC unit or near the turn-
around time.
According to the Truesdail test results, the total emissions from
both stacks of the ESP unit amounted to 5,300 dry m3 (185,500 dscf)/
minute a particulate emission rate of 8.3 kg (18.4 lb)/hr, a SO2 emission
rate of 565 ppmv, a N0x emission rate of 180 kg (396 lb)/hr, and an
ammonia discharge rate of 25 kg (52 lb)/hr using EPA Method 5 sampling
techniques.
It should be pointed out that Truesdail adjusted the weight of
material collected during the sampling run for ammonium sulfate concen-
tration. The particulate matter collected was analyzed for ammonium
(NH^+) ion. All ammonium ion found was considered to be complexed as
ammonium sulfate. The calculated weight of ammonium sulfate was sub-
tracted from the total weight of sample collected before the emission
rates were calculated.
Truesdail's rationale for making this "correction" is not directly
stated in the test results. However, it appears that the reason is
related to the fact that Mobil must inject ammonia gas into the ESP unit
to obtain desirable operating conditions. The ammonia apparently
improves the ionization of the gases within the ESP. The injected
ammonia reportedly reacts with sulfur compounds present in the FCC
regenerator off-gases to form ammonium sulfate. Since Mobil must add
the ammonia to obtain the desired ESP operating efficiency, Truesdail
apparently rationalzies that they should not be penalized for the result-
ing formation of ammonium sulfate.

The LAAPCD tested the FCC Unit stack on September 20, 1973 (test
C-2047) and on March 28-29, 1974 (test C-2122). Test results for
the two dates were respectively as follows:

discharge allowed by Rule 54; however no citation was issued to Mobil by
the LAAPCD.
Sulfur Recovery Unit. The LAAPCD source tested the stacks at the
sulfur recovery complex on August 20, 1974 (test C-2081) and December
12, 1974 (test C-2234) [Appendix K]. During the December 12 test, only
the B tail gas unit and the incinerator were operating.

Computed Emission Rates
Theoretical emission factors for various emission sources found
at petroleum refineries are listed in Table 9.1-1 on page 9.1-3 of
the EPA publication AP-42 Compilation of Air Pollutant Emission Factors,
-------
18
Second Edition (second printing with Supplements 1-4). These emission
factors were used to compute the emission rates in Table 1. Emissions
from hydrocarbon storage tanks have not been calculated for this report.
They will be included in a separate report being prepared by NEIC which
will summarize storage tank emissions from all refineries in Los Angeles
County.
Boilers and Process Heaters. As can be seen from the listing of
process heaters and steam boilers shown in Appendix C, a substantial
number of these units can be fired with both fuel gas and fuel oil.
Theoretical emissions from these units are calculated using different
factors for each fuel type used. It can be seen that a wide range of
emissions can exist depending on the available fuel situation. Table 1
summarizes the theoretical emissions for two possible situations: 1)
all units are being utilized (100% of capacity) and all units are fueled
with fuel gas, and 2) all units are in operation at 100% of capacity and
fuel gas is curtailed so that fuel oil is being used in those units
which can use oil. Realizing that a wide variety of unit/fuel combinations
exist, for this analysis situation (1) is considered the most frequent
operating mode, and situation (2) is considered the least probable mode.
For these calculations, the heat content of refinery fuel gas was
assumed to be 11.4 X 10^ cal/m^ (1,280 Btu/scf) and that of the fuel oil
to be 9.4 X 109 cal/m3 (142,000 Btu/gal).
The process heaters and boilers are major contributors of nitrogen
oxides. Depending on the fuel use pattern at the refinery, calculated
nitrogen dioxide emissions for these units range from 350 to 730 kg (780
to 1,620 lb)/hr as N02- If the refinery is on fuel gas curtailment
these units are also potential large sources of particulate matter, 170
kg (375 lb)/hr and sulfur oxides, 450 kg (1,000 lb)/hr as S02-

Fluid Catalytic Cracking Unit. Table 1 summarizes the calculated
theoretical emissons from this unit. These theoretical emissions were
also calculated using AP-42 emission factors for FCC units with attendant
CO boilers and electrostatic precipitators. The calculated value for
particulate emissions using the average emission factor value listed in
AP-42 is 50 kg (105 lb)/hr. This value is in excess of the maximum
allowable emission rate under the LAAPCD Rule 54 which is 13.6 kg (30
lb)/hr. However, it should be emphasized that the AP-42 emission factor
is an average value for the industry and that the Mobil precipitator may
be more efficient than the average unit. Truesdail Laboratories' test
in May 1974 and the LAAPCD tests of September 1973 and March 1974
indicated a much lower emission rate. As noted before, Truesdail's
calculations are subject to varying interpretations.
The calculated emission rates for other pollutants from the FCC
unit indicate that substantial amounts of sulfur dioxide, hydrocarbon,
and nitrogen dioxide are emitted from this unit. The calculated theoretical
values are 520 kg (1,150 lb)/hr, 230 kg (515 lb)/hr and 75 kg (165
lb)/hr, respectively.
Other Sources. Table 3 summarizes the calculated theoretical
emission rates from other sources within the refinery. In general, AP-
42 gives only hydrocarbon emission factors for these sources. The major
source appears to be leakage from pipeline valves and flanges and process
drains, which amounts to 70 kg (150 lb)/hr and 275 kg (610 lb)/hr,
respectively.
SUMMARY OF VIOLATIONS
A review of the LAAPCD records indicates [Appendix L] that Mobil
has had 28 citations since January 1972. There have been no citations
to Mobil since April 27, 1975. On April 7, 1975, the company was cited
-------
21
for excessive visible emissions (Rule 50) from the Zinc Thermal Oxider.
This case was dismissed as a result of the company plea. Another citation
was issued on April 27, 1975, for excessive visible emissions (Rule 50)
from the sulfur recovery tail gas unit. The company pleaded nolo contendre.
INSPECTION SUMMARY
At the time of this inspection, all major process units except the
CO boiler were in operation.
All process units, storage vessels, potential pollution emission
points and pollution control devices in use at the refinery were observed
during the inspection. No visible emissions were detected from any of
the process heaters or incinerators. The flare systems also appeared to
be operating correctly.
During the physical inspection, it was noted that the piping and
handrails at the sulfur recovery plant were severely corroded and the
oxidized Stretford reagent was very black; it should be red-brown. In
addition, a moderate ammonia odor was noted. The Intertech SO2 analyzer
was reading 100 ppmv SOg on the incinerator stack.
The Lear Siegler opacity meter at the FCC unit was reading 9-10%
opacity on the FCC emissions when observed.
General housekeeping at the refinery appeared to be very good. The
main process areas were neat with no noticeable spills, leaks, etc.
The Mobil-Torrance refinery has a rather unique group called "en-
vironmental inspectors." This group of five Mobil employees are charged
with inspecting the refinery in the same manner the LAAPCD inspectors
would. This program has drastically reduced (to zero) the number of
citations that Mobil has received from the LAAPCD since mid-1975.

Dear
Pursuant to the authority contained in Section 114 of the Clean Air
Act, as amended, representatives of the EPA will conduct, within the
next year, inspections of the Allied Chemical Corp. operations to
ascertain compliance with the Federally approved California State
Implementation Plan.
Representatives from the Environmental Protection Agency will
observe the facility's process operations, inspect monitoring and
laboratory equipment and analytical methods, review source test data,
examine appropriate records, etc. A process and air pollution flow
diagram or a blueprint of the facility and production information should
be available for the EPA personnel at the start of the inspections.
Detailed information about air pollution sources will be discussed
during these inspections. Attached is a partial list of the information
that will be needed in order to complete these inspections. We would
appreciate it if you could inform the appropriate company personnel
about the forthcoming inspections so that the necessary information will
be readily available and the inspection can be expedited.
If you have any questions concerning these inspections, please feel
free to contact Arnold Den, Chief, Air Investigations Section, Region
IX, San Francisco, at 415/556-8752.
A representative of the EPA (Dr. Wayne Smith or Mr. David Brooman,

In the Hatter of )
MOBIL OIL CORPORATION j Case Ko. 1183-48
Bnergency Variance—Sec. 24292(a) of )
the California Health and Safety Coda )
FINDINGS 0?* THE HEART HG BOARD
This petition for a variance came before the Hearing
Board on January 14, 1975, pursuant to notice duly given. All
Hearing Board members were present. Petitioner was represented
by John A. Lllygren, Attorney at Law. Respondent, Air Pollution
Control Officer, was represented by John H. Larson, County
Counsel, by his deputy John V. Khitsett.
Petitioner is operating an oil refinery at 3700 kest
190th Street in the City of Torrance. Part of the refinery
consists of a fluid catalytic cracking unit and its control
equipment. Part of the control equipment consists of a carbon
monoxide boiler end an electrostatic precipitator. One section
of the carbon monoxide boiler is known as the economizer
section. On January 10, 1975. a leak developed In the econo-
mizer section which made it necessary to shutdown the carbon
monoxide boiler for repairs. While this is down, experience
has shown that there will be a violation of Rule 71 of tho
Rules and Regulations of the Air Pollution Control District
end Section 24280 of the California Health and Safety Code,
and a possible violation of Rules 50 and 54 and Section 24242
on en Intermittent basis, particularly during start up.
Upon reading and filing the verified petition, the
Hearing Board further finds that petitioner is in violation
of Rule 71 of the Rules and Regulations of the Air Pollution
Control District and Section 24280 of the California Health
-------
end Safety Code end will periodically violate Rules 50 end 54
and Section 24242 until the carbon monoxide boiler is started
up and is back in service in approximately ten days; that,
due to conditions beyond the reasonable control of petitioner *
requiring compliance would result lii the practical closing and
elimination of a lawful business; that such closing would be
without a corresponding benefit in reducing air contaminants;
that, due to no fault on the part of petitioner, an emergency
exists, and, good cause appearing therefor, an emergency
variance should be granted.
The Hearing Board further finds that this is a
recurring condition due to the failure of tubes in the econo-
mizer section. This appears to be due to a physical weakness
and petitioner has a program in progress to replace the tubes
vith a different material and to use helloarc welding Instead
of conventional welding. It expects that when this i3
completed, the frequent breakdowns will be eliminated.
Petitioner has heretofore filed a compliance schedule and
increments of progress showing the date of completion of the
above-mentioned corrective program as December 31» 1975.
Respondent united with petitioner in requesting the adoption
of this compliance schedule and increments of progress.
NOW, THEREFORE, petitioner is granted en emergency
variance from Rules 50, 54, and 71 of the Rules and Regulations
Of the Air Pollution Control District and Sections 24242 and
24280 of the California Health and Safety Code to commence
forthwith and continue until January 22, 1975* Petitioner's
compliance date as to this episode is January 22, 1975.
Petitioner's compliance schedule and Increments of
progress are adopted a3 follows and petitioner is ordered to
comply therewith:
1. Date contracts were awarded September 16, 1974
2. Submission to District of written „ ,,
proposal October 11. 1974
-------
3. Initiation of on-site construction October 31. 1975
4. Construction or Installation completed December 31, 1975
5. Final completion (expected end of
breakdowns) December 31, 1975

The test rocultc indicate that there were come rnercaptanc present in the flue
Coo al tail-gas Unit B. This in ieflected on the table on pace 6, v.hich j.hovc
tl)al tlie total sulfur (us SO2) is higher than ;dl the individually neasured
culfur compounds added together.
The total sulfur at the incinerator outlet shows there arc some sulfur co:;:-
pounds coming into the incinerator from other Gourcc_ besides the tiul-Gas
unit outlet B.
SAMPLING /-in ANALYTICAL PROCCDUR^S
Gas Flow Rate
The cos f]ov/ rates at the tail-gas Unit E and the incinerator outlet vero
determined by traversing the staclis with a Type-S pitot tube, Pagnehc-lic
gage and a theinomctcr.
Determination of COS, CS2 ^2^
Gas camples were taken directly from the stack in 2-litcr evacuated flask.",
and v.'cre a^aly^ed for COS, CS2 and I'.^S by Gas chromatography \n th a flo.T.e

The Inspectors entered the defendant corporation's
petroleum refinery complex and contacted Mr. J.R„ Thomas,
Environmental Surveillance. Mr. Thomas conducted the
Inspectors to the sulfur recovery area where they were
joined by Mr. William Frazcr, Shift Superintendent. No
emissions or mal-odors were noted by the Inspectors in
this area.
The Inspectors entered the sulfur recovery area control
room to see the tail gas incinerator temperature chart.
They reported that the chart had recorded a steady 1200°F.
during the time when they were observing the excessive
emissions. Other charts of equipment in the sulfur
recovery area had recorded considerable variations during
the past hour of operation. Mr. Thomas and Mr„ Frazer
did not comment on the recording charts or on the emissions
described to them by the Inspectors.
The Inspectors informed Mr. Thomas and Mr. Frazer that
a report would be written on their observations and that
a citation would probably be issued against the defendant
corporation for excessive emissions.
On April 28, 1975, Inspector Powell contacted Mr. Ron
Wilkness, Supervisor, Environmental Surveillance, and
Mr. Worth Dickey, Environmental Engineer, at the defendant
corporation's petroleum refinery complex on a follow-up
investigation. They accompanied him to the sulfur recovery
area where he reviewed the operations of the previous night
and he verified that conditions in the Sulfur Recovery Unit
#1 and Tail Gas Incinerator Unit "B", concurrent in time
with the previously observed sulfur emissions, could have
led to excessive sulfur emissions from the tail gas
incinerator stack.
In normal operation, the Sulfur Recovery Units' off-gases
pass to the tail gas unit where the residual gaseous sulfur
is precipitated out of the gas stream, then the excess air,
hydrogen gas and traces of hydrogen sulfide are burned off
in the Tail Gas Incinerator. If liquid sulfur passes from
the Sulfur Recovery Units to the Tail Gas Unit, there will
be excessive sulfur emissions exiting the incinerator stack.

(Cont. Page 3)
Inspector Powell examined the record charts for the line
burner (which accepts off-gas from the Sulfur Recovery
Units) and noted that during the time when the Inspectors
observed excessive sulfur emissions, there were reduced
line burner temperatures plus increased fuel gas and air
supply to the line burner. Inspector Powell is of the
opinion that the indicated line burner upset resulted from
a slug of liquid sulfur coming from the Sulfur Recovery
Unit. A natural result of the line burner upset is excessive
sulfur emissions from the tail gas incinerator stack.
As a result of the observations by Inspector Brewer and
Schreckengost and the investigation by Inspector Powell,
a notice was served by Inspector Powell, on April 29, 1975,
to the defendant corporation charging a violation of Rule
50 of the Rules and Regulations of the Air Pollution Control
District, The notice was served to the defendant corporation
through Mr. Carl Mehl, Environmental Control Manager,
