摘要
主要介绍了分离异丙醇-水共沸物的几种方法,其中不仅包括传统的苯共沸精馏工艺,而且还包含:吸附蒸馏、萃取精馏、渗透汽化法、加盐萃取共沸精馏等几种新工艺,并对这几种方法进行了比较。
This paper introduces some methods that separate azeotropic water/IPA mixtures, which not only includes traditional azeotropic distillation,but also includes some new technologies,such as:adsorptive distillation,extraction distillation,pervaporization,adding salt extraction-azeotropic distillation and distillation-pervaporization hybrid process. Meanwhile,a brief comparison was made among all the separation methods.
