چکیده انگلیسی
This study reports selectivities and permeances of pure nitrogen, oxygen, ethylene, ethane, propylene and propane and their mixtures through composite poly(dimethylsiloxane) (PDMS)-polysulfone membrane at ambient temperature. It was observed that both propylene and/or propane significantly plasticized PDMS coating in pure as well as mixed gas permeation experiments. Above the plasticization pressure, the permeance order was PC3>PC3>PC2>PC2>PO2>PN2, which matched the solubility order. However, permeance order was changed to PC3>PC3>PC2>PC2>PO2>PN2 below the plasticization pressure, showing that propylene was more permeable than propane. Furthermore, plasticization caused coupling effects for ethylene, ethane and nitrogen in the presence of propylene and propane.
