燃煤烟气CO₂捕集技术的发展与应用

The Development and Application for CO₂ Capture from Coal-Fired Flue Gas

CO2捕集技术主要有吸收分离法、吸附分离法、低温蒸馏法、化学循环燃烧、膜分离法、水合物等。本文对这些技术进行了分析比较,探讨了各技术的优缺点与适应场合。根据电厂燃煤烟气的特点,化学吸收法技术可靠性强、经济性高,能够满足发电厂对燃煤烟气捕集回收CO2以减少污染物排放的要求。

The technology of carbon dioxide capture mainly includes the methods of absorption separation, cryogenic distillation, chemical circulation combustion, membrane absorption and hydrate. Comparative analysis is made in this paper with focus on the characteristics and applicable ranges of these technologies. According to the characteristics of flue gas from coal-fired power plant, chemical absorption technology has the advantage of reliability and economy and achieves the goal of reducing carbon dioxide emissions.
