Calculate volume stock tank vapors to size Vapor Recovery Unit

Calculate volume stock tank vapors to size Vapor Recovery Unit

(OP)
I need to calculate volume stock tank vapors (scfd) to size Vapor Recovery Unit. The total volume needs to account for flash losses, working and breathing losses.

The facility currently has a 3-phase production separator which operates at normal operation pressure 50 psi ( min 35 psi, max 70 psi). The separator dumps the oil into 2-500 bbl oil tanks. The water is dumped into 2-500 bbl water tanks and gas is sold through a meter run. The gas needs to be pressurized to a range of 35-70 psig to be able to be transferred to the main compressor.

Production separator normal operation pressure: 50 psi.
Temperature: 90 F

Oil production rate: 250 bbl/day              
Water production rate:     3500 bbls/day        
Gas production rate:250,000 scfd.    

API gravity: 39
SG of water: 1.135

Gas analysis:
Mole %
N2    1.8938
CO2    0.2237
H2S      0.0047
C1    80.7232
C2    8.0648
C3    4.2067
iC4    0.8600
nC4    1.6946
iC5    0.7648
nC5    0.3976
C6+    1.1661
Totals    100

Could someone please provide me some help, guidelines, publications, or excel calculations to get me started on this exercise. I appreciate any help.

Thanks in advance!!
