摘　　要：采用聚酰亚胺中空纤维膜以气流吹扫操作方式进行乙醇气相脱水研究 ,干燥的吹扫气流由压缩空气膜法脱湿组件提供 ,此两过程构成了集成膜过程 ;讨论了膜材料改性、吹扫气流的湿度和流速、操作温度等条件对乙醇脱水效率的影响 .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.
