四氢呋喃-水共沸物体系分离方法

Separation methods for tetrahydrofuran-water azeotropic system

从工业化分离方法与新型分离方法 2个层面分别介绍近年来四氢呋喃-水共沸物分离的研究进展。工业化分离方法主要包括萃取精馏和变压共沸精馏,新型分离方法中主要讨论了吸附法与渗透蒸发方法。对于工业分离方法,以后的发展方向将是在保证分离要求的前提下,进一步减少能耗、满足绿色环保的要求。

The research progress on separation of tetrahydrofuran-water azeotrope in recent years is reviewed from the aspects of industrialized separation methods and novel separation approaches. The industrialized separation methods reviewed mainly include the extractive distillation method and the pressure swing azeotropic distillation method. Novel separation approaches discussed mainly include the adsorption and pervaporation methods. As for the industrialized separation methods,the future direction will develop towards reducing energy consumption and meeting the requirement of environmental protection regulations in the premise of ensuring requirements of separation.
