| Abstract: | The polydimethylisiloxane(PDMS)/polysulfone(PS) composite hollow fiber membranes for the process of hydrogen recovery from refinery dry gas is investigated. The effects of some factors, which are the PDMS, catalyst and cross-linker concentration,on gas separation performance of composite membranes were discussed. The influences of feed flow rate, feed pressure, partial pressure of hydrogen in permeated gas and temperature have also been considered and analyzed. |
