Air Emissions Inventory
2008 AIR EMISSIONS INVENTORY SUPPORTING DOCUMENTATION
Emission Source ID No: NS-B
Emission Source Description: VE-North EVE Manufacturing Process
EVE Process Emissions
Page 1 of 13
Process & Emission Description: The VE-North EVE manufacturing process is a continuous chemical reaction.
All emissions from the process are vented through the Nafion Division Waste Gas Scrubber (Control Device ID
No. NCD-Hdr) which has a documented control efficiency of 99.6% for all acid fluoride compounds. Some
emitted compounds are assumed to pass completely through the scrubber, so the control efficiency for those
compounds is assumed to be 0%. The control of emissions of specific compounds will be addressed and detailed
in the following pages.
The EVE process in VE-North emits compounds in the acid fluoride family. In the presence of water (such as in
atmospheric moisture), these acid fluorides can eventually hydrolyze to hydrogen fluoride. For the purpose of this
emissions inventory, a conservative approach will be taken and the acid fluorides will be reported both as a VOC
and as the equivalent quantity of hydrogen fluoride.
Basis and Assumptions:
- The EVE process flowsheet is the basis for relative concentrations of before -control emissions of gaseous
wastes.
- Calculations of point source emissions are based on actual vent flow totals taken from the IP21 Historian.
- All emission determination calculations are available on the EXCEL spreadsheet found at:
S:/Everyone/martinas/Emissions/2008/VEN Air Emissions 2008.xls.

The estimated BF equivalent emissions were determined by multiplying the total emission quantity of
an acid fluoride by the ratio of the molecular weight of BF divided by the molecular weight of the
specific acid fluoride. This is based on the fact that one mole of an acid fluoride will generate one mole
of BF.
For example, if 100 lb. of MAE was emitted:
20 lb/mol BF X 100 lb/yr Equipment MAE = 6.0 lb/yr BF
332 lb/mol MAE
