How to Calculate and Solve for Petrosky-Farshad Gas Solubility Parameter | The Calculator Encyclopedia

The image above represents petrosky-farshad gas solubility parameter.

To compute for the petrosky-farshad gas solubility parameter, two essential parameters are needed and these parameters are API Gravity (°API) and temperature (°Rankine) (T).

The formula for calculating the petrosky-farshad gas solubility parameter:

Rs = [7.716(10-4) (°API)1.541] – [4.561(10-5) (T -460)1.3911]

where:

Rs = Petrosky-Farshad Gas Solubility Parameter, x
°API = API Gravity
T = Temperature (°Rankine)

Let’s solve an example;
Find the petrosky-farshad gas solubility parameter with an API Gravity of 11 and a temperature of 90.

This implies that;

°API = API Gravity = 11
T = Temperature (°Rankine) = 90

Rs = [7.716(10-4) (°API)1.541] – [4.561(10-5) (T -460)1.3911]
Rs = [7.716(10-4) (11)1.541] – [4.561(10-5) (90 – 460)1.3911]
Rs = [7.716(10-4) (11)1.541] – [4.561(10-5) (-370)1.3911]
Rs = [7.716(10-4) (11)1.541] – [4.561(10-5) (NaN)]
Rs = [7.716(10-4) (40.2518)] – [4.561(10-5) (NaN)]
Rs = [0.03105] – [4.561(10-5) (NaN)]
Rs = 0.03105 – NaN
Rs = NaN

Therefore, the Petrosky-Farshad gas solubility parameter, x is NaN.
