Abstract: As a new technology of carbon dioxide separation from flue gas，membrane absorption has caught more attention. An introduction of the fundamentals of membrane absorption is presented，together with an analysis of membrane absorption from three aspects，including system process，absorption solution，and membrane contactors and membrane materials. In conclusion，the prospect of future development is discussed.

摘要： 在介绍膜吸收法的基本原理的基础上，主要从系统工艺、吸收液以及所采用的膜接触器结构和膜材料等3个方面对膜吸收法分离烟气中二氧化碳的研究现状进行了分析，并对膜吸收法的发展方向进行了展望。
