摘要: 目前,对于燃煤电厂燃烧后烟气中CO2的捕集方法主要包括化学吸收法、吸附法、膜分离法和低温蒸馏法。化学吸收法是目前最成熟的CO2捕集方法,但是吸收剂再生能耗较高,且存在二次污染、设备腐蚀等问题。因此开发新型高效、低能耗的捕集技术尤为重要。本文主要从两个方面(膜材料的设计、膜分离过程系统设计的优化)对燃煤电厂烟气中CO2膜分离技术进行综述,并总结了实际燃煤锅炉烟气中共存气态组分和细颗粒物对膜分离CO2的影响,最后对膜法分离燃煤电厂烟气中CO2的发展趋势进行展望。分析表明,近年来膜材料开发、膜分离过程系统的设计及优化等方面的研究发展迅速,使得膜分离法在CO2捕集效率及能耗等方面展现出巨大的潜力,因此膜分离法在燃煤电厂烟气中CO2捕集领域有广阔的应用前景。

Abstract: At present,the method of capturing CO2 in flue gas after combustion of coal fired power plant mainly includes chemical absorption,adsorption,membrane separation,low-temperature distillation. Chemical absorption is the most mature method,but the energy consumption of absorbent regeneration is higher,and there are some problems such as secondary pollution,equipment corrosion and so on. So it is very important to develop new technology with high efficiency and low energy consumption. This paper mainly reviewed the application of membrane separation technology in coal-fired power plant CO2 capture. The development in the membrane material design,optimization of membrane separation processes,and the influence of coexisting gaseous components and particles on the membrane separation CO2 in the flue gas of the coal fired boiler was summarized. At last,future trends of membrane technology has been put forward. Analysis showed that recent advances in the development of membrane materials and the optimization of membrane separation process have been rapidly developed. Therefore,membrane separation has shown a significant potential in high CO2 capture efficiency and low energy consumption. So the membrane separation has broad application prospects in the field of CO2 capture in the flue gas of coal-fired power plants.

Key words: coal-fired power plant, flue gases, CO2 capture, membrane material, system design
