| Abstract: | Polyimide hollow fiber membranes were used in vapor permeation for gas phase dehydration on ethanol. Dry air sweeping operation was used and the dry air was supplied by a dehumidification membrane module of compressed air. A integrated membrane process was composed. The effects of some factors, such as the modification of membrane materials, the humidity and current velocity of sweeping air, the operation temperature, on the efficiency of dehydration were discussed. |
