For the equpiment emission calculations the inventory shown below is conservative and based on plant and process diagrams. Note that the calculations below include equipment emissions inside buildings as well as vessel emissions outside (fugitive emissions). A. Fugitive Emissions from Crude E-fluids tote: This 180-gallon tote is filled with dry crude E-fluids from the 55 gallon drum. This material then gets transported to the Polymers area for use. This tote can hold several batches of material. This filling activity occurs on the outside of the E2 building. Assume the filling is at 30 degrees Celsius and assume that one batch of E-fluids displaces 33% of the tote, or 60 gallons of volume, during filling. These emissions will be "Fugitive" in nature. Calculations: PV = nRT (assumes the Ideal Gas Law) 33% Tote Volume = 60 gallons / 7.48 gal/ft3 = 8.02 ft3 Contents of vessel Component MW Kgs Moles Mol % Vapor Pressure psia Partial Pressure* (psia) El 286 22.00 0.08 15.09 9.70 1.46 E2 452 189.20 0.42 82.12 0.85 0.70 E3 618 8.80 0.01 2.79 0.17 0.0047 Total L 220.00 1 0.51 1 100% * Partial Pressure = Vapor Pressure multiplied by MoI% divided by 100% Tank temperature = 30 degrees Celsius is equal to 545.69 degrees R R = 10.73 psia-ft3/lb-mol/degR For E1: n = moles of E1 = (Partial pressure of E1) * (Volume) / (R) / (Temperature) n = 1.46 psia x 8.02 ft3 = 0.0020 Ib-mol E1 10.73 psia-ft3/lb-mol/degR 545.69 degrees R 0.0020 Ib-mol E1 x 286 Ib E1 = 0.57 Ib El/batch Ib-mol E1 For E2: n = moles of E2 = (Partial pressure of E2) * (Volume) / (R) / (Temperature) n = 0.70 psia x 8.02 ft3 = 0.0010 Ib-mol E2 10.73 psia-ft3/lb-mol/degR 545.69 degrees R 0.0010 Ib-mol E2 x 452 Ib E2 = 0.43 Ib E2/batch Ib-mol E2 For E3: n = moles of E3 = (Partial pressure of E3) * (Volume) / (R) / (Temperature) n = 0.0047 psia x 8.02 ft3 = 0.000007 Ib-mol E3 10.73 psia-ft3/lb-mol/degR 545.69 degrees R 0.000007 lb-mol E3 x 618 Ib E3 = 0.004 Ib E3/batch Ib-mol E3 DEQ-CFW 00086128 • • E-Fluids Process Total Fugitive Emissions from E2-Fluids process Chemical Ib/batch No. of batches lbs El 0.57 77 44.2 E2 0.43 77 33.3 E3 0.004 77 0.3 Total 1 1 77.7 B. Equipment Emissions From Valves, Pumps and Flanges Fugitive/Equipment Emissions Page 10 of 11 The emission rates for valves, flanges, etc. have been established by the DuPont Company. The emission rates from these types of equipment in the E-fluids process is considered "Excellent" and therefore the following rates are use: valve = (0.00039 Ib/hr), flange = (0.00018 Ib/hr) Calculations: Valve emissions: 134 valves x 0.00039 Ib/hr/valve = Flange emissions: 20 flanges x 0.00018 lb/hr/flange = Total equipment emission rate VOC: 0.0559 Ib/hr VOC x 1,128 operating hrs/year 63.0 Ib/yr VOC 0.0523 0 Ib/hr VOC 0.0036 0 lb/hr VOC 0.0559 0 Ib/hr VOC By Component: We will assume that equipment emissions are the same composition as the crude E-fluids (i.e. 10% E1, 86% E2, and 4% E3) Total Equipment Emissions from E-fluids process: Chemical Chemical Fraction Total Equipment Emission Rate Ib/yr) Total Equipment Emission Rate Ib/yr E1 10% 63.0 6.3 E2 86% 63.0 54.2 E3 4% 63.0 2.5 Total 63.0 Where the Chemical Emission Rate equals the Total Equipment Emission Rate multiplied by the Chemical Fraction DEQ-CFW 00086129 E-Fluids Process 2002 Emissions Accidental Releases Page 11 of 11 01, =idental Releases t® AfMq§phere A.
