摘要
论述了两种膜法分离技术———渗透汽化法和蒸汽渗透法从近似共沸物中分离无水乙醇的研究现状,列出了渗透汽化法中具有工业应用前景的复合膜材料及中空纤维膜组件的研究结果,并对两种膜法分离技术进行了较全面的比较。
In this paper,two technologies of membrane separation of anhydrous ethanol,namely,pervaporation and vapor permeation,from near azeotropic ethanol-water are presented,and the progresses are also discussed.The research results of composite membrane and hollow fibre module with industrial prospect are listed.The overall comparisions have been made between the two membrane separation technologies.
