ENVIROTECH i DOHRMANN 3240 Scon boulevard Santa Clara, California 95050 Telephone (408) 249-6000 Telex 346 395 July 3, 1975 Mr. Paul Fetzcr Continental Oil Co. P.O. Box 605 Westlake, LA 70669 Dear Mr. Fetzer: We have completed the analysis of your samples. Project No. 1048B. The results are summarized in the attached Application Report. Also attached are copies of other pertinent literature. This sample analysis exemplifies the method of determining organic chlorocarbons in aqueous solutions of inorganic chlorides. We have prepared a standard consisting of a one percent solution of sodium chloride and 834 ng/jul of organic chlorine (from 1, 2 - dichloroethane). The standard was analyzed for chlorine under normal system operating conditions. In addition, the furnace inlet temperature was reduced to 200 C to assure that all inorganic salts (including ammonium chloride) remained in the boat. Analysis under these conditions yielded 835 ng/pl Cl, which is essentially the same as the value of the prepared standard. Following analysis of several samples, the boat should be rinsed with deionized water to remove the salt accumulation. If you have any questions concerning these results, please feel free to contact us directly or Mr. John Zimmerman, our sales engineer in your area. Sincerely: MKC:ki cc: Mr. Homer Hackett Mr. John Zimmerman Dohrmann ~ L'nvirotech P.O. Box 42295 Houston, TX 77042 (713) 4G7-0G24 M.K.

INSTRUMENTAL.CONDITIONS: As per Application Note MC-201, except inlet between 170 - 400 CC. SAMPLE TREATMENT: Two standards were mixed using 1, 2 dichlorocthane. 911 ppm iii water and 834 ppm in 1% NaCl solution. Mininert sample vials (with sliding sheath - valve and septum) were used.

Also same concentrations in the range of 1000-2000 ppm Cl are recommended with sample volumes of 2 /il. RECOMMENDATIONS: The MCTS-20 System with SBI Single Boat Inlet is well suited for analysis of these samples. WC 000011383 -jv _ 3/11/76 VC' PLAITT - bill?SCO'! CCMIbOLS Follo;vin.i is a sunnary of developments leading no our current program to control VCM emissions to comply with che proposed EPA regulation: (1) The T?A rirst proposed regulations on December 24, 1975. Teas2 regulations could require all vent streams from any emission source to contain less than 10 ppm of VCM excluding the oxychicrination vent which -i-j required to emit no .''.ora than 0.02 pounds/100 pounds of EEC produced. Compliance is required 9G days from the effective date (r.cv estimated to be in October, 1975), but EPA can grant a waiver of compliance of up to two /ears from the effective data. From various EPA drafts of the standard and discussions with EPA va believe re understand what a control device must do to reduce vent concentrations of VCM. (2) Either catalytic oxidation (being developed in E&D) or incineration have been considered at suitable control methods. During the pre paration of the 1276 Capital Budget projected operating cost savings were believed to favor catalytic oxidation for which $5,171-2! was budgeted. (3) Early in 1976 it was learned that the feed to the catalytic oxidizer would be flammable and potentially unsafe. The cost to correct this has eliminated much of the economic incentive for this process. Xn additd :.r., there was insufficient time to complete the necessary cm sir. :erir.; to meet the timetable of the standard. This has. forced subst:_zufcion to the incineration scheme and, therefore, that design is L-eir.g developed. The project cost, however, has remained at approx imate. * 51MM, Both systems have planned to use cl.amshell neutralisa tion -o destroy the dSlate hydrochloric acid formed from scrubbing the . .-'v.bus Cion :::;s es .

VVC 000011384 SUMMARY PAGE TWO (5) Many options of size ana configuration of the incineration system have been considered. Balancing economics, pollution and logistical concerns, a single train is judged best consisting of: (1) A 48MM BTU/hcur incinerator rich a waste heat boiler (2; A hydrogen chloride scrubbing unit (3) A 4,200 lb./hour dry hydrogen chloride recovery unit (6) A light and a heavy by-prcduct stream are produced in the VCM plant. The "light ends" consisting mostly of ethyl chloride and chloroform are currently sold. The "heavy ends" or tars are shipped tc ??G and incinerated for a fee. Our planned incinerator capacity will be sufficient to burr, vents and Lars but not "light ends" and plans are to use it this way. Although continued sales of "light ends" are anticipated, the incinerator will be designed so that they may be burned, ihouid this be desirable, the feed would be switched to "light :nds" and the tars bached out by sending them again to PPG, for example. The v;astc heat boiler will produce steam for plant use. The entire incineration crain will be constructed so a parallel unit can b- easily installed later if we expand the plant or if the EPA react:2 a second incinerator to maintain compliance while operating the zh~z when the other incinerator malfunctions. vve 000011885
