Modeling and simulation of pervaporation process was considered in this paper. Pervaporation process has been modeled based on conservation law of mass and energy. The model was developed in Matlab environment and the model equations were solved by numerical methods. It was used for simulation of pervaporation process on separation of an azeotropic mixture of isopropanol-water. Initially, the performed simulation data was compared with a published experimental data and the developed model was validated with errors of 7% on temperature; 1.9% and 2.2% on permeate flow rate and water content, respectively. Later, the developed model was implemented for simulation of the pervaporation process under adiabatic and interstage heating conditions. The simulation results showed that under adiabatic condition and feed temperature of 100˚C results on retentate temperature of 65˚C and required membrane area of 5610 m2. But, by applying interstage heating condition and using of 4 sequential stages, the required membrane area can be reduced more than 5 times, 1028 m2.
