For the equipment emission calculations the -inventory shown below is conservative and based on plant and process diagrams. Note that the division scrubber efficiency is 99.6% for control of acid fluorides. A.

For example, the stack emission of BFP from the EVE process was 663 lb., with the total stack emission from the Vinyl Ethers North processes being 13,747 pounds. The total equipment emissions were 1,435 pounds (less ADN and AN since they are only emitted through equipment). Therefore, the BFP equipment emissions from the EVE process were determined by: 580 lb. BFP X 2,022 lb. Total equipment emissions less ADN and AN 50,666 lb. Total stack emmisions = 23.1 1b.
