Pervaporative Separation of Ethanol/Water Mixture Using PDMS/blended PES Composite Membrane: CFD Simulation

Ethanol will be the most favorable fuel in the near future because it is produced from renewable sources and it is environmentally friendly too [1]. Pervaporation as a separationprocess does not need any extra reagent while the other technologies like extraction and extractive distillation need.The most alcohol-permselective polymeric membrane isPDMS [2]. Computational Fluid Dynamic (CFD) technique was found to be practical to simulate the mass transfer inpervaporative membranes [3]. So, in this study conservation equations were solved simultaneously by CFD to improve amodel, capable of predicting mass transfer in the pervaporative synthesized PDMS membrane
