Evaluation of CO2/CH4 Gas Separation in PVA and PVC Mixed Matrix Membrane Permeation Models

The purpose of this paper is to examine, predict and compare gas transport behavior of mixed matrixmembranes (MMMs) combined with porous particles with different polymeric matrix . In this regard, composite flatsheet membranes are prepared from different amounts of poly(Polyvinyl alcohol) (PVA) and poly vinyl chloride(PVC)Gas permeability were studied for the prepared membranes. Then these membranes modelled was performed byMaxwell, and the results of Maxwell model with the experimental data were compared and the percentage of error wasshown. Studied results showed that despite higher permeability emissions of carbon dioxide with PVC membrane gridwith carbon nanotubes in the membrane of PVA but Maxwell model for PVA membranes without any additive as apolymeric membrane has provided more acceptable results.
