引言 醇／水体系分离一直是化工生产中的重要环节，高效的醇／水分离技术能够使醇的产量大大提高，满足日益增长的工业生产需求。传统的分离方法如精馏、萃取等已经相当成熟，但是这些方法在工业生产过程中能耗巨大，越来越受到面临能源资源匮乏的当代社会的关注和制约。在此背景下，

英文摘要：

Non-porous polyether sulfone hollow fibers （with a 5μm poly （dimethylsiloxane） coating） were used as structured packing in the distillation of ethanol-water solutions. In this novel membrane contaetor, liquid flowed through the lumens of the fibers, and vapor flowed countercurrently outside the fibers. The results showed that the new membrane contactor gave better, more productive separations than traditional packing in distillation. The minimal HETP of hollow fibers could reach as low as 5.8 era, and the contaetor worked well above the limit where flooding normally occurs in conventional cases. The overall masstransfer coefficient and individual mass-transfer coefficients based on the gas side and liquid side were calculated respectively. The theoretical analysis indicated that the resistance in the liquid was responsible for more than half of the total resistance.
