Process simulators are commonly used for effective modeling, simulation, and optimization of separation techniques. A novel mathematical model was developed to determine the component fluxes, separation factor and pervaporation separation index (PSI) considering the effects of different physico-chemical parameters (temperature, pressure, feed concentration), on the pervaporative separation of benzene from model pyrolysis gasoline (benzene/1-octene) with a fabricated insitu(nano)silver/polyvinyl alcohol membrane. The simulation was done using MATLAB R2013 software. Estimation of PSI, the unique performance parameter, precisely provides the pervaporation separation efficiency. The maximum simulated and experimental PSI values for 0.3 mole fraction of benzene in feed at 303 K and 1 mm Hg downstream pressure are 14.25 kg/m 2 /h and 14.26 kg/m 2 /h, respectively. The error functions are presented in terms of Objective Function, Standard Deviation, Standard Error and Root Mean Square Error; all of them were ≪1. Good agreement between the experimental and simulated values endorsed the validity of the model.
