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 PPVE 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 bothas a VOC and as the equivalent quantity of hydrogen fluoride. Basis and Assumptions: - The PPVE 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/cecilkd/EmissionsNES 2004 Emissions.xls.
