2007 Fugitive Emissions Determination
Fugitive Emissions (FE) are a function of the number of emission points in the plant (valves, flanges, pump seals). For
the fugitive 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. Fugitive Emissions from Condensation Reactor System
Condensation Tower (vents to stackl
Valve emissions: 322 valves x 0.00039 Ib/hr/valve = 0.126 Ib/hr VOC from FE
Flange emissions: 644 flanges x 0.00018 Ib/hr/flange = 0.116 Ib/hr VOC from FE
Pump emissions: 6 pump x 0.00115 Ib/hr/pump = 0.007 Ib/hr VOC from FE
Total fugitive emission rate = 0.248 Ib/hr VOC from FE
Condensation Tower VOC
Total Condensation Fugitive Emissions:
VOC 0.248 Ib/hr FE
x 8765 Operating hr/yr
2177 lb FE

C. Acetonitrile fugitive emissions
No normal process vents of AN to stack. Equipment emissions are estimated above for normal process composition
and leaks. A material balance is also done to ensure all AN losses are accounted for. When material balance
shows negative loss, only the estimated equipment emissions are included.
VOC Emission
AN to hydrocarbon waste from VE-S = total HC waste - VE-N waste= 45,371
Assume that: 5% of spent acetonitrile are fluorocarbons.
AN portion of hydrocarbon waste stream:
45,371 kg to H!C waste
x (1-(.05))
= 43,102 kg AN to H/C waste
9,245 kg AN fed
43,102 kg AN to waste
-33,857 kg AN lost = 0 kg VOC
0 lb VOC additional AN loss
Note: Based on this material balance, it is assumed that no AN is emitted to atmosphere from fugitive emissions,
other than what is determined above.
The amount of hydrocarbon sent to waste is probably overestimated due to inaccuracies in calculation of VE-N
portion of the waste.
