Compressibility Factor Calculator for Natural Gas

This is a sample of the compressibility factor calculator. To access the working calculator, please sign up for free membership trial.

The application presented here can be used to calculate the compressibility factor or z factor of natural gas, at given conditions of temperature and pressure. Other gas contents such as Nitrogen, Carbon Dioxide and Hydrogen Sulfide also have effect on the compressibility factor of the gas stream as a whole. This calculator is based on Brill and Beggs correlation for natural gas compressibility factor (z factor) calculation.
