2005 Equipment Emissions Determination
Equipment Emissions (EE) are a function of the number of emission points in the plant (valves, flanges, pump seals).
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.

462 valves x valves x 0.00039 1b/hr/valve = 0.180 lb/hr VOC from EE
924 flanges x flanges x 0.00018 lb/hr/flangc = 0.166 lb/hr VOC from EE
0 pumps x pumps x 0.00115 lb/hr/pump = 0.000 lb/hr VOC from EE
Total fugitive emission rate = 0.347 lb/hr VOC from EE
From Acid Fluorides: 0.347 lb/hr VOC from EE
x 3,803 hours/year
x 90% fraction of EE that are acid fluorides
= 1,186 lb VOC
From Non -Acid Fluorides: 0.347 lb/hr VOC from EE
x 3,803 hours/year
x 10% fraction of EE that are non-acid fluorides
132 lb VOC
Total Condensation Tower Equipment Emissions:
VOC: 1,186 lb VOC from acid fluorides
+ 132 lb VOC from non-acid fluorides
= 1,318 lb VOC

Note: Speciated equipment emissions were estimated by assuming that each compound's equipment emission
concentration was equal to that compound's stack emission fraction of the total stack emission.
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. BFP
