Abstract:
A set of non-crosslinked Carboxymethylcellulose(CMC) membranes were prepared with different concentrations of polymer. Then, the permeability of pure CO2, N2 and CH4 was measured through these membranes in dry state to investigate the influence of polymer concentration and applied feed pressure on permeability and selectivity of these membranes. As expected, the permeability of CO2 through CMC membranes was higher than the other gases because of the polar carboxyl groups of CMC which increased the solubility of CO2 by enhancing the interactions between this gas and the polymer. A comparison of permeabilities revealed that the permeability of gases decreased by increasing the CMC concentration or decreasing the feed pressure. Also, the permeability ratio of CO2/ CH4 and CO2/ N2 increase as CMC concentration increased. The applied feed pressure had no significant effect on the permeability of N2, while, the permeability of CO2 and CH4 increased
