2004 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.
Condensation Tower (vents to stack)
Valve emissions: 462 valves
x valves x 0.00039 lb/hr/valve =
0.180
lb/hr VOC
Flange emissions: 924 flanges
x flanges x 0.00018 lb/hr/flange =
0.166

Pump emissions: 0 pumps

*Valve and Flange Factors can be found on Fugitive Emission Leak rates worksheet
Condensation Tower VOC
From Acid Fluorides: 0.347 lb/hr VOC from EE
x 6,163 hours/year
x 90% fraction of EE that are acid fluorides
= 1,922 lb VOC
From Non -Acid Fluorides: 0.347 lb/hr VOC from EE
x 6,163 hours/year
x 10% fraction of EE that are non-acid fluorides
= 214 lb VOC
Total Condensation Tower Equipment Emissions:
VOC: 1,922 lb VOC from acid fluorides
0 = + 214 lb VOC from non-acid fluorides
2,135 lb VOC

From Non -Acid Fluorides: 0.122 lb/hr VOC from EE
x 6,163 hours/year
x 98% fraction of EE that are non-acid fluorides
= 734 lb VOC
Total Refining System Equipment Emissions:
VOC: 15 lb VOC from acid fluorides
+ 734 lb VOC from non-acid fluorides
= 749 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 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).
