modeling of ideal and real gas behaviors for prediction of performance in membrane permeators

By increasing the pressure, the properties of gas mixtures deviate from ideal state. This study investigates the effect of Real gas behavior on prediction of modeling gas separation hollow fiber membrane modules as a common technology in industrial processes. The principal governing equation are solved using Finite Element Method as a modern numeric method. The validity of the developed models was examined indicating good agreements between prediction and experimental data provided in literature. The results demonstrate the importance of considering nonideal behavior of mixture gases. The findings reveal that comparison to the ideal gas behavior the model with real gas behavior has better predictions. Also among other common equation of states, Soave−Redlich−Kwong equation of state represents better predictions
