Samel son D. Dupre L. Atwell L. Joiner The various vinyl vent sources .-mre discussed relative to the operation of the Terminal (Refer to simplified diagram of Mantua VCM Stg. System SK-1). Maximum vents from the VCM Storage Tanks and Refrigeration System were determined by stack sampling (Reference Report Br 20139 dated 1/12/76, Table 1 attached). Vents from other sources were calculated. The methods considered to dispose of the VCM vent sources were discussed. 1. EDO Absorption - Too complex, expensive, and could cause VCM Spec, problems (EDC), 2. Catalytic or Thermal Decomposition - Difficult to operate, creates other emission. problems (HCL). 3. Carbon Adsorption The carbon adsorption system as shown on SK-2 was selected as being the best for the Terminal. This system is simple to operate and eliminates future emission problems by concentrating the VCM for return to storage. The system is marketed by Oxycatalyst. Mo systems are in service at this time for VCM, however one unit is sold which will ship in October of this year. Teneco has a carbon system using steam for regeneration, however this creates other emission problems. The technology for using activated carbon to adsorb vinyl chloride is sound (Reference attached Calgon Tech nical Data). One problem is heat formation which Oxycatlyst feels they have solved with their bed design. VCM emission from the system is guaranteed at 10PPM or less. An Order-of-Magnitude installed cost is $261,000 based on budget quotations for all of the equipment. It was agreed to develoo an ACT Estimate based on the Carbon 3ed Adsorption System Design. In view of tne latest developments it was also agreed to include in the ACT Escmato tne cost to make Terminal Vaive Stem and Pumo Seal Leakage comely ,vito ::-,e proposed EPA Vinyl Regulations. An Order-ofMagnitude cost mo m 'e schedule for the latter were requested by -June 1.
