摘要
主要介绍了异丙醇-水分离的几种工艺和新方法。在介绍异丙醇脱水常规工艺的基础上,重点阐述隔壁共沸精馏、间歇萃取精馏、吸附蒸馏和膜分离法等新工艺,具体分析了各种方法的优缺点及研究情况,并展望了异丙醇-水分离工艺的前景。
This paper introduces several separation technologies for isopropanol - water system, which include not only traditional azeotropic distillation and extraction distillation, but also new membrane separation techniques, such as dividing wall azeotropic distillation, batch extractive distillation, membrane distillation, pervaporation, and membrane contactor. Meanwhile, a brief comparison of characteristics and efficiency for unit operation is made among all the separation methods. Their advantages and disadvantages are discussed specifically, and the future process of isopropanol dehydration technology is prospected.
