BUTYRALDEHYDE STORAGE TANK
(BS-1)
EMISSIONS DETERMINATION
Butyraldehyde (BA) emissions from Storage Tank Condenser (BCD-1):
BA (breathing losses) to condenser = 2,482 lb/yr
BA Vapor Pressure at 71.37 °F = 1.844 psi
BA Vapor Pressure at 32 °F = 0.558 psi
0 lb (O.558psi) lb
BA emissions from condenser = 2,482 n X 1.844 psi = 751-

FUGITIVE EMISSIONS CALCULATIONS
i. FIXED LOSSES
A. Unloading System
Leak rate = (pump losses + liquid valve losses + gas valve losses + flange losses) x
(weight fraction BA) x (total hours)
= [(1)(0.109) + (9)(0.016) + (1)(0.012)+ (27)(0.0018)] (1.0) (8760 hrs.)
= [0.109 + 0.144 + 0.012 + 0.0491] (1.0) (8760)
= (0.314 lbs./hr) (8760 hrs/yr.)
= 2,750lbs./yr.
B. Vapor Return System

C. BA Storage Tank
1. Liquid Flanges/Valves
Leak rate = (liq. valve losses + flange losses) (weight fraction BA) (tot. oper. hrs.)
= [(2)(0.016) + (8)(0.0018)] (1.0) (8760)]
= [0.032 + 0.014] (1) (8760)
= 406lbs./yr.
2. Vapor Flanges/Conservation Vents
Leak Rate = (C/V losses + vapor flange losses) (weight fraction BA) (Tot. oper. hrs.)
= [(2)(0.224) + (12)(0.0018)] (0.143) (2.57) (8760)
= [0.448 + 0.0216] (0.143) (2.57) (8760)
= 1,511lb/yr.
