چکیده:

Composite membranes are suitable for natural gas sweetening. In this work the effects of preparation parameters were investigated. Increasing PES concentration improvesmembrane selectivity to 18.0. Addition of DMF as support solvent enhances the selectivity to19.68. Longer delay time of 3 minimproves the selectivity to 21.54 and permeability to 4.89 GPU. Increasing PDMS concentration to 10% lead to the selectivity of
