摘要：

Experimental data of the pervaporation of aqueous ethanol solutions through aromatic polyimide hollow fiber were obtained. The effects of temperature, pressure and the composition of aqueous ethanol solution on permeability and selectivity were experimentally examined. The values of the separation factor of water were between 16-55. It was found that the overall permeation coefficient defined with fugacity difference across a membrane was the most rational for the simple evaluation of permeation fluxes in polymide, because the values of the permeation coefficient defined with the fugacity difference were kepe constant for the data over wide ranges of feed compositions and temperatures. The permeation coefficient for water was three times that in vapor permeation at higher temperature, and that for ethanol was twenty times higher.
