摘要
渗透气化是一种新型的膜分离技术,因其具有独特的优势已被广泛应用于乙醇-水的分离。从渗透气化的原理和特点出发,介绍了渗透气化膜材料以及渗透气化与精馏、化学反应耦合等技术,并概述了国内外渗透气化膜分离技术在乙醇-水分离中的应用现状。
Being a new membrane separation technique,pervaporation has great advantages in ethanol and water separation.The characteristics and principles of pervaporation,membrane materials,and techniques of pervaporation integrated with fine distillation and reaction were introduced in this paper.In the end,the present status of pervaporation in ethanol industrial application was also summarized.
