DeBernardi, Plant Manager Conoco Chemicals Continental Oil Company Post Office Box 60S Westlake, LA 70669 Dear Mr. DeBernardi: I would like to thank you fdr assisting us in our development of new source performance stand ard (NSPS) for distillation operations in the synthetic organic chemich Is manufacturing industry (SOCMI), by providing information on your ethyl ene dichloride and vinyl chloride processes, The following informatio i based on our telephone conversation on October 16, 1980, and a lett er from you to Mr. D.R. Goodwin dated May 26, 1978. Could you pie ase review the following information and write to me as to whether or not this is correct? Ethylene Pichloride Process Totally, there are four distillation units in this process, There are two steam stripping units. These are nonvacuum operations, The noncondensables frcm the steam stripper, mainly CO^, are sent to the incinerator. EDC purification coijisi^ts of the other two distillation units. These are also oper ted under nonvacuum conditions, The noncondensables from both the EDC purification columns are sent to the incinerator. Vinyl Chloride Monomer Proce ss : There are three nonvacuum distillation operations in this process. The quench tower is the first distillation unit. The noncondensables from this are sent l;o the next distillation unit. Economics / Engineering VVC 0000123T7 2- - The next distillatio imit is the HC1 removal column. The noncondensables are further processed and are recycled to the oxychlorination reactor. The third distillat ion unit has no noncondensables exiting the accummulator. Ther e is a manual vent which is routed to the incinerator. The Incinerator: The incinerator is designed to treat offgases from (1) direct chlorination, (2) 1 oad:.ng, (3) distillation offgases, and (4) liquid by-products. The incinerator is followed by a HC1 removal scrubber. This incinerator sy stem has cost approximately $13 million. The oxychlorination reactor vents are not routed to the incinerator due to the large vo Lume and very low heat content. All the noncondensahlei from various distillation units are routed to the incinerator ay liatural flow. No devices like compressor, blower, etc., are present for this purpose. Further Information Requsst^d: Having found the above information very useful, we would like to request the following information for a better understanding of controls for chlorinated hydrocarbons fr0m distillation units. Provide the data on flow and compositions (both organic and inorganic) for the following s treams: Offgases from th tvo steam strippers in the EDC process before they combine with tHe inlet gases to incinerator. Offgases from EDC purification columns in the EDC process before they combine with the inlet gases to incinerator. Total offgases entering the incinerator. What is the material of construction of pipes carrying the noncondensables from distillation units ? Does the presence of chlorinated hydrocarbon require any special mat erial? Provide a rough skei: ch of the layout of the EDC plant marking only the distillation un ts and the incinerator, indicating the distances in between these un ts. vvc 0000l2a78  What types of valve|s a e used in the pipeline from distillation units to the incinerate r (e.g., flow control valve, flame arrestor, backflow control valve etc.)? Note: Questions 3 and 4 wiil be useful to cost a typical piping system. Please feel free to contact me if you have any questions.

Box 60630 New Orleans, LA 70160 Dear Sir: Per your letter of Octobe r 5, 1980 stating that the Conoco VCM Plant permit (No. 1424T) reques t as been approved by the Assistant Secretary of the Louisiana Environ njent al Control Commission, we would like to point out an error in the emis ion allowable total for hydrocarbons. The Environmental Protection Age icy is requesting that we send them a letter of approval from the Stat e of Louisiana with correct emissions allowable totals, therefore, we asq that you re-issue the letter of approval using the corrected numbers. The following maximum emi ssipns allowables would apply for the permit: Particulates Hydrocarbons Sulfur Dioxide Carbon Monoxide Nitrogen Dioxid HC1 & Cl 86.83 23.39 68.45 17.73 244.97 434.69 On Page 3 of the revised Emiksion Inventory Questionnaire issued to your office on August 21, 1980 the emission rates for alkanes/paraffins should be 1.19 lbs./hr. and 4.89 to ns/yr. instead of 1.98 lbs./hr. and 8.12 tons/yr. A mistake was made when otaling the emission rates from the individual point sources. (See attached sheet) We ask that you make thes e re visions as soon as possible since the EPA is delaying action on our PS D a implication until we send a letter of permit approval from the State, If there are any questions concerning these modifica tions, please contact Gar|y Fo shee at (318) 491-5062. ^ J.
