Compressibility Factor Calculator for Natural Gas

Use our compressibility factor calculator online tool.

Our calculator is based on Standing and Katz model, and the pseudocritical property-calculation methods of Sutton are valid only for mixtures of hydrocarbon gases.

Our calculator is based also on Wichert and Aziz to take on account significant fractions of acid gases, specifically carbon dioxide (CO2) and hydrogen sulfide (H2S).

Our calculator is also based on a new explicit z-factor is developed as a multi-stage correlation based on Hall and Yarborough’s implicit correlation.
