4. APPROACH TO EMISSION ESTIMATION

5. THE GENERAL EQUATION FOR EMISSIONS ESTIMATION • E = A x EF x (1-ER/100) where: E = emissions; A = activity rate; EF = emission factor, and ER =overall emission reduction efficiency, %

6. TOTAL LOSSES FROM FIXED ROOF TANKS • LT = LS + LW where: LT = total losses, lb/yr LS = standing storage losses, lb/yr, LW = working losses, lb/yr

7. STANDING STORAGE LOSS • LS = 365 VV WV KE KS where: LS = standing storage loss, lb/yr VV = vapor space volume, ft3, see Equation 3-3 WV = stock vapor density, lb/ft3 KE = vapor space expansion factor, dimensionless KS = vented vapor saturation factor, dimensionless 365 = constant, the number of daily events in a year,

8. WORKING LOSS • LW =0.0010 MV PVA Q KN KP where: LW = working loss, lb/yr MV = vapor molecular weight, lb/lb-mole PVA = vapor pressure at daily average liquid surface temperature, psia Q = annual net throughput, bbl/yr KN = working loss turnover (saturation) factor, dimensionless for turnovers >36, KN = (180 + N)/6N for turnovers ≤36, KN = 1 N = number of turnovers per year, dimensionless

9. TYPES OF STORAGE TANKS • 1. Fixed-roof tanks; • 2. External floating roof tanks; • 3. Internal floating roof tanks; • 4. Domed external floating roof tanks; • 5. Horizontal tanks; • 6. Pressure tanks; and • 7. Variable vapor space tanks.
