膜分离技术是当代化工领域的高新技术。由于它是解决人类面临的能源、资源、环境等重大问题的新技术，所以近30多年来取得了极为迅速的发展。渗透汽化膜分离技术是一种新型膜分离技术，是典型的节能技术和清洁生产技术。用于恒沸体系分离，与传统的恒沸蒸馏和萃取精馏相比，节能1/3~1/2，运行费节约至少50%。本文介绍了国内外渗透汽化脱水膜工业应用情况，并重点介绍了渗透汽化汽油脱硫膜、透甲醇膜、透乙醇膜、透碳酸二甲酯膜、芳烃/烷烃分离膜研究进展及其应用的可能性。

Membrane separation technology is contemporarily a high and new technology in chemical engineering. It has been consequently developed rapidly in recent 30 years due to the availability of solving many serious problems,such as energy,resources and environment. Membrane separation technology of pervaporation as a novel separation technology is typically energy-saving and cleaner-production technology. Compared to the conventional azeotropicdis-tillation and extractive distillation applied to azeotropic systems,pervaporation process could lead to an energy saving of 1/3~1/2 and decrease operating costs even no less than 50%. The industrial applications of the pervaporation dehydration over the world are introduced,and re-search progresses and industrial feasibilities of several pervaporation membranes are shown in this paper,which cover gasoline desulfurization membranes,methanol and ethanolpermselec-tive membranes,dimerthyl carbonate/methanol and arene/alkane separation membranes.
