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. Equipment Emissions from Condensation Reactor System Assume that: 100% of process materials are VOCs ; 90% are acid fluorides that are emitted from the stack; 10% are non-acid fluorides that are emitted from the stack.

For example, the stack emission of HFP 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).
