几种化工分离技术的发展与应用

Development and Application of Several Chemical Separation Technologies

化工分离操作是石油化工、精细化工、生物化工、制药等行业生产过程中最重要的单元操作之一,以生产过程中混合物的分离、产物的提取或纯化为研究对象。在低碳经济、可持续发展的背景下,化工分离操作朝着两个方向发展:一是传统分离技术改进发展以及新技术的不断出现;二是各种分离技术的耦合使用。文章主要就最近几年化工分离方法的发展及应用情况进行阐述。

Chemical separation operation is one of the most important unit operations in the production process of petroleum chemical, fine chemical, biological chemical, pharmaceutical industries, and so on. In the background of low-carbon economy and sustainable development, chemical separation is developing towards two directions： one is the improvement of traditional separation techniques and emerging of new techniques constantly; the other is the coupling of various separation techniques. In this article, development and application of chemical separation methods in recent years were introduced.
