z Factor

Compute z factor from pseudo reduced pressure and temperature

Gas compressibility factor (z-factor) is an important parameter widely used in petroleum and chemical engineering. Accurate and fast calculation of this parameter is of crucial need and challenges a large number of simulators used in engineering. In this app, we are presenting a better way for calculation of this parameter.

This application uses a 2-10-10-1 neural network to calculate compressibility factor (z-factor) of natural hydrocarbon gases based on Standing-Katz and Katz charts.
