The expansion will be accomplished by adding a parallel train to the VCM system and debottlqnec cing existing equipment. The technology will be based on a well proven system. Process emissions wivt be controlled by recovering hydrocarbon as much as practical and then b|y incineration to meet the NESHAP Standard of less than 10 ppm VCM in any veny gas. Process incinerato rs J/ill be controlled with wet scrubbers and the new heater will use LoNOx b urnirs. Sulphur oxide emis sions will be controlled by using fuel of less than 0,72 sulfur content. The debottleneckinh techniques employed will result in hydrocarbon and CO being reduced by 4603 and 1768 tons per year respectively. Dispersion modeling supplied by the company indicates that ambient air quality standards will not be violated. Table I shows the effect of this plant expansion on emissions of the facility as a whole. NSPS does not apply to this facility.
