Diisocyants (-Isocyanato-1-(isocyanatomethyl)-1, 3,3-trimethylcyclohexane (IPDI)), polyols (Polycaprolactone) and chain extender (1-4butanodiol) were incorporated in preparation of polyurethane based membranes. The prepared membranes were characterized by Fourier Transform Infrared spectroscopy (FTIR), permeability and selectivity of prepared membranes was measured by gas permeation cell. The effect of Mw content of polycaprolactone (750, 1000, 1250, 1600 and 2000), feed pressure (0.1-0.4MPa), operating temperature (20-50oC), and hard segment combination of (diiosocyante +chain extender) effect on transport property of CO2/CH4 and CO2/N2 selectivity were investigated. CO2/CH4 gas mixture selectivity enhanced 46% in PUM15 (2000Mw) as compared to membrane sample PUM1 (750Mw) is 2.4% and CO2/N2 selectivity is 51% in PUM15 (2000Mw) as compared to membrane sample PUM1 (750Mw) is 2.6%.The results revealed that PUM15 (Mw2000) display CO2 permeability of 39.7 Barrer, higher than the PUM1 (750) is 4.3 Barrer. As the operating temperature increased from 20to 50oC CH4 permeability increased about.9 to 8.6 Barrer for 750Mw (PUM11) and 2000Mw (PUM15) membranes samples. The correspondence decrease in the CO2/CH4 selectivity as compared to CO2/N2 is 46% and 51%. This is supported that high molecular weight polyurethane membrane are good CO2 selective as compared to lower molecular weight polyurethane membranes. Because the heat trapping capabilities of this gas molecule into Environment may cause global warming.
