【 摘 要 】

Membrane-based techniques are always praised as energy-saving and efficient methods to retrofit some conventional technological processes that are usually high energy-consumption, especially distillaiton in separation of azeotrope. This work reviews the recent progresses of separation processes by membrane-based techniques for liquid mixtures which are difficult to be separated by normal distillation. Membrane-based techniques such as membrane distillation, pervaporation, and membrane structured packing are concretely described. In addition, a membrane hybrid process is presented. Compared with conventional separation, membrane-based techniques and membrane hybrid processes will play important role in the separation of liquid mixture due to the investment, operating cost, safety and separation efficiency.
