摘要
渗透蒸发由于其对近沸物和恒沸混合物高效的分离性能而成为当今一个基本的分离操作单元。本文首先对渗透蒸发装置及分离性能表征简要总结,然后重点概述了对沸石膜的渗透蒸发应用和渗透蒸发过程影响因素,最后针对当前研究现状,展望了沸石膜在渗透蒸发方面的发展前景。
Pervaporation was nowadays considered as a basic unit operation for separation of liquid mixtures because of its efficiency in separating azeotropic and close-boiling mixtures.The pervaporation device and the separating performance characterization were summarized briefly,and an overview of the pervaporation application and the pervaporation affect factor through zeolite membrane was focused on.For the current research status,further prospects in this field were also discussed at last.
