How to Calculate and Solve for Petrosky-Farshad Gas Solubility in a Fluid | The Calculator Encyclopedia

To calculate the petrosky-farshad gas solubility, three essential parameters are needed, and these parameters are gas specific gravity (γ_g), petrosky-farshad gas solubility parameter (x) and pressure (P).

The formula for calculating the Petrosky-Farshad gas solubility:

R_s = [(^P/_112.727 + 12.340)γ_g^0.8439 10^x]^1.7384

Where:

R_s = Petrosky-Farshad Gas Solubility
γ_g = Gas Specific Gravity
x = Petrosky-Farshad Gas Solubility Parameter
P = Pressure

Let’s solve an example;
Find the petrosky-farshad gas solubility when the gas specific gravity is 16, the petrosky-farshad gas solubility parameter is 22 and the pressure is 80.

This implies that;

γ_g = Gas Specific Gravity = 16
x = Petrosky-Farshad Gas Solubility Parameter = 22
P = Pressure = 80

R_s = [(^P/_112.727 + 12.340)γ_g^0.8439 10^x]^1.7384
R_s = [(⁸⁰/_112.727 + 12.340)16^0.8439 x 10²²]^1.9384
Then, R_s = [(0.709 + 12.340)16^0.8439 x 10²²]^1.9384
R_s = [(13.049)16^0.8439 x 10²²]^1.9384
R_s = [(13.049)10.379 x 10²²]^1.9384
So, R_s = [1.354e+24]^1.9384
R_s = 8.925e+41
