0 1998 - Waste Fluorocarbon Tanks Emissions
This system includes the Waste Fluorocarbon Storage Tank (Receiver), Reactor Tank, Shipping
Tank, and Catch Tank
Neutralized waste mixed fluorocarbon generated in 1998 = 1,552,326 lb.
Waste Fluorocarbons generated in 1998 =
315, 621 The
KOH as 45 wt. %
1,131,900 lb.
Water added to process for maintenance reasons
1,452 lb.
Miscellaneous material shipped as RCRA waste for billing
reasons, but was not RCRA waste.
103,640 lb.
WASTE FLUOROCARBON STORAGE TANK (RECEIVER TANK) EMISSIONS
BASIS:
• Tank Volume = 1150 gallons = 153.7 cu. ft.
• Control of venting tank high pressure is locked out until pressure >_ 700 kPa = 101.5 psig
• Maintenance vents can be done to allow for work to be done on the system using the
0 service manifold.
• Both emergency vents and maintenance vents go to Waste Gas Scrubber
• Fluorocarbon liquid SPG = 1.4
Summary - maintenance vents and pressure relief device vent.
HF Emissions* - assume that all vapor is HF (MW=20) and is scrubber in WGS at 99.6%
efficiency.
Actual emissions = 2.95 lb. HF/yr
VOC emissions* — Assume vapor is Freon® 113 (MW = 187) and scrubber has no effect.
Actual emissions = 1346 lb. F-133/yr = 0.67 Ton/yr
'Calculation is based on change in pressure and tank weight during the venting time frame. See
attached spreadsheet.

•
BASIS:
• Tank Volume = 1150 gallons = 153.7 cu. ft.
• Control of venting tank high pressure is locked out until pressure >_ 700 kPa = 101.5 psig
• Maintenance vents can be done to allow for work to be done on the system using the
service manifold.
• Both emergency vents and maintenance vents go to Waste Gas Scrubber
• Fluorocarbon liquid SPG = 1.4
No emissions of material from reactor are present for 1998.
WASTE FLUOROCARBON SHIPPING TANK EMISSIONS
Neutralizing waste fluorocarbons generates nonvolatile water soluble fluorocarbon salts. The
shipping tank vents to the waste gas scrubber which would remove any acidic or water soluble
component that might enter the scrubber.
There are no emissions from this shipping tank for 1998.
