2004 AIR EMISSIONS INVENTORY SUPPORTING DOCUMENTATION
Emission Source ID No: NS-C
Emission Source Description: VE-South PMVE Only Manufacturing Process
Process & Emission Description: The VE-South PMVE Only manufacturing process is a continuous chemical reaction. All
emissions from the process are vented through the VE-South Waste Gas Scrubber (Control Device ID No. NCD-Hdr2) 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 PMVE Only process in VE-South 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 PMVE Only process flowsheet is the basis for relative concentrations of before -control emissions of gaseous wastes.
- The flowsheet is based on a 67:33 PAF/COF2 precursor feed ratio. In 2004, the precursor feed ratio was 100% COF2 during a
PMVE Only Campaign.
- Accordingly, a flowsheet correction was made.
PAF ratio is 0.00 COF2 Ratio is 1.00.
- 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/cecilkd/Emissions/2004/VES 2004 Emissions.xls.

The estimated HF equivalent emissions from Equipment Emissions were determined by multiplying the
COF2 HF Potential (0.606 lb. HF/lb. COF2) by the COF2 Equipment Emissions
for the Compound
0.606 lb/yr HF x 84.64 lb/yr Equipment COF2 = 51 lb/yr HF
