Propane: Liquid to Gas Phase Conversion
Propane: Liquid to Gas Phase Conversion
(OP)
I need to know how to claculate what volume of propane GAS will result from 3200 liters of LIQUID propane. Can one of you chemical/petroleums help me with this?





RE: Propane: Liquid to Gas Phase Conversion
The gas volume is similar. You know the mass of gas, you need to calculate or lookup the density which is a factor of pressure and temperature. Density of propane density is available from the ASHRAE data books, Perry's Handbook of chemical engineers or you can calculate it.
For a gas, density = P*MW/(Z*R*T).
Density is lb/ft3
P is pressure, psia
MW is molecular weight, 44 for propane
Z is the compressibility factor, it depends on the pressure and temperature. For 100 or 200 psig and ambient temperatures, you can take it as 1.0.
R is the gas constant, 10.73 psia*ft3/lbmole/R
T is the temperature is degrees rankine.
