2.1 BENZENE/TOLUENE COLUMN RECOVERY SYSTEM 

(Figure 2.1, points 2 and 3) 

The recovered liquids from the benzene/toluene recovery system were 

obtained at point 2. Point 3 was a sample of the non-condensables from 

the recovery system to the plant fuel. Both samples were taken simultaneously. 

The liquid sample at point 2 separated into a hydrocarbon and a 

water layer. The samples were shaken to form a single phase and then 

injected into the gas chromatograph. Results are shown in Table 2.1. 

The volumes of each layer were measured and the percent water layer 1s 

reported in Table 2.1. The liquid flow rate was determined by recording 

the time required to accumulate a total volume of five gallons. The 

total condensabies recovered were directed into the five gallon container 

by closing off th" normal recovery drain valve and shunting the flow to 

the container by opening the sampling valve. 

Results of the analysis of point 3 samples are shown in Table 2.2. 

Flows at point 3 were obtained from a plant orifice which was connected 

to a square root differential pressure meter. The results of these 

flows are shown in Table 2.2. The orifice calibration sheet and example 

calculations are contained in the Appendices. 

2.2 COLUMN HOT WELL VENTS 

(Figure 2.1, sample points 6, 7, 8, 9) 

This section includes the results of testing at the ethyl benzene 

column hotwell liquid (point 6) and vent to the atmosphere (point 7). 

Also discussed are results from the vents of the PEB hotwell (point 8) 

The sample location numerical designations are not sequential. Potential test locations in the process were identified prior to a preliminary survey at the facility. During the initial visit, it was 

determined that some of the proposed locations either did not exist 

or could not be sampled. To maintain continuity for the overall 

project record, the original location designations were retained, 

therefore, results for test Points 1, 4, 5, and 10 do not exist.

and the styrene purification hot well (Point 9) . The four sampling 

points were tested simultaneously. The results of the analyses are 

contained in Tables 2.3 through 2.6. 

Flows were monitored at the hot well vents (Points 7, 8, and 9) 

before and after testing with a 4-inch vane anemometer, which was 

adapted to fit the two and one half Inch vent pipe. The four-Inch 

diameter was used in the calculations for total flow. Calculations and 

data are contained in Appendix A. Flows of the liquids were not determined. 

The liquid samples were analyzed at the Raleigh, N.C. Laboratory. 

They were thoroughly mixed and injected into the gas chromatograph. 

There was no apparent water/hydrocarbon phase separation in these 

samples. The main constituent was water with trace amounts of hydrocarbons present. The results of the liquid samples are listed in Table 

2.3. 

2.3 STEAM SUPERHEATER (Figure 2.2) 

The purpose of this third series of tests was to determine the 

destruction efficiency for the incineration of benzene in the process 

heater. The fuel input to the boiler (Point 12), and the outlet to 

atmosphere of the steam superheater (Point 11) were tested simultaneously and the results obtained by on-site analysis. The benzene 

concentration found in the first run at the outlet location was much 

higher than expected. Blank tests on the sampling system confirmed that 

residual organic contamination was present 1n the apparatus. The 

sampling procedures were changed so that glass sampling flasks were used 

in place of the EPA Method 110 flexible bag system. An initial run 

indicated that the modified procedure had eliminated the contamination. 

However, subsequent samples yielded results that were variable and 

1 

The test plan included measurement of flow and VOC concentration from 

the vent to atmosphere of a collector pump for the ethyl benzene recycle 

column and styrene purification column hot well overflows. At the time 

of testing, it was determined that the pumping rate from the collector 

was metered based on a constant level control and operates continuously. 

Therefore, there was theoretically no net displacement of air to the 

atmosphere during operation. Preliminary flow measurements confirmed 

that no flow to atmosphere was occuring, therefore no samples were 

collected for VOC and benzene determination.

inconsistent. In an attempt to clarify the results, blanks on the glass 

sampling system and the gas chromatograph injection system were run. A 

satisfactory blank of the system was not achieved. Appendix A contains 

the blank series that was run during testing. Gas chromatograph results 

reported in the following tables are uncorrected for blanks. These 

results are continued in Tables 2.7 and 2.8. Table 2.9 contains results 

of the benzene destruction efficiency and flow data. 

The study of the superheater revealed problems in the testing 

procedures. (The sequence of problems are presented with the Superheater 

Study in Appendix A. The first problem in testing was the contamination 

of the Method 110 Sampling Apparatus. The first test run at the Superheater outlet revealed a high level of benzene (^ 60 ppm). The source 

of this high level was due impart to the memory effect of the sampling 

apparatus being previously used for testing the high levels of benzene 

at the hotwell vents. A blanking study of the sampling apparatus revealed 

the sample bags contained a 20 ppm level of benzene after being purged 

with nitrogen; a check of the flowmeters in the system revealed a 20 ppm 

benzene level of contamination. The blanking procedure was carried out 

on the detection instruments and a nitrogen purging of the sample loop 

gave benzene results of no lower than 4 ppm. An alternative to the 

sampling procedure was adapted since adequate cleaning of the Method 110 

apparatus could not be achieved. 

The sampling system was adapted in order to obtain grab samples in 

a glass flask. The glass sampling bomb method also encountered difficulties. 

The cleaning of the glass bomb with isopropyl alcohol was believed to 

interfere with the benzene reading due to similar retention times. The 

10 cc syringe used for sample injection from the glass sample bomb was 

determined to be too small a volume to adequately flush a GC sample loop 

of 2-4 ml total volume. A blank procedure was attempted on the glass 

bomb sample method and the result was approximately at 2 ppm of benzene. 

Blanking of the sampling loop and gas chromatograph between each test 

run yielded results at the 1 ppm level. This consistent background of 

benzene was considered to be due in part to the time for an unheated 

sample to purge back to zero. 
P.6 

Ambient samples were obtained with an OVA total hydrocarbon analyzer 

and the result was benzene levels ranging from 5-10 ppm. The testing of 

the superheater was ended and hypotheses on the testing procedures were 

derived from subsequent lab studies and information gathered during 

testing. Some of the conclusions are: 

1. The sampling appratus cannot be adequately cleaned by 

simple purging after exposure to high level aromatics (example • 

benzene). 

2. Glassware exposed to aromatic compounds cannot be cleaned 

using purging and solvent rinses alone. 

3. An unheated sample loop on the gas chromatograph does not 

purge to zero quickly. 

4. The syringe used for sample injection was too small to 

adequately flush and fill the G.C. sample loops. 

With these testing problems in mind the preparation, sampling 

and analysis procedure for further testing of this type have been modified 

to accomodate these conclusions. 

Due to the configuration of the stack and absence of adequate 

ports, an outlet volumetric flow rate could not be measured. Since it 

is necessary to calculate the benzene removal effeciency on a mass 

basis, a combustion calculation using the fuel and flue gas analysis was 

performed to calculate a combustion dilution factor for adjusting the 

measured inlet and outlet benzene concentrations to the same volume 

basis. 

A carbon balance based oh the combustion calculations yields 

significantly different exhaust gas C02 concentrations from those 

directly measured. Based on this difference, it is probable that the 

fuel gas analyses are Inaccurate. Due to the difficulty of achieving 

accurate results on the GC system used for C, - Cg analysis when C1 

exceeds 5 volume %, the results for methane are probably low, and since 

hydrogen was determined by difference, that result is probably high. 
P.7 

Due to the difficulties encountered with interferences, blanking, 

analysis, and combustion calculations the flue gas analysis obtained at 

the superheater cannot be used with confidence. These sampling and 

analysis problems have been subsequently remedied and tests conducted 

after this do not contain data with these problems.
