摘要
随着社会经济的迅速发展，人类对于化石燃料的需求量越来越大，燃料燃烧后排放的有害物质也越来越多，全球环境污染问题严峻，温室效应尤为严重。CO2是主要温室气体，CO2总排放量的75％是由石化燃料燃烧产生的，我国CO2排放总量的一半来自电力工业。中国作为负责任的国家，到2020年，中国要实现单位国内生产总值CO2排放量比2005年下降40％～45％这一目标。因此，火电厂CO2减排任务重大，采用C02捕集与封存技术能减少电厂80％-95％排放量，理论上具有巨大的减排潜力，是当今世界公认的CO2减排的重要途径。目前电厂捕集技术大体上分作三种：燃烧前捕集、燃烧后捕集和富氧燃烧捕集。
With the rapid development of social economy, the demand for fossil fuels grow fast, emission of harmful substances become more and more, the global environmental pollution problems become more serious, especially greenhouse effect. CO2 is the main greenhouse gas, CO2 is 75 % of the total emissions produced by burning fossil fuels. Half of the total CO2 emissions are from power industry in our country. As a responsible country, by2020, China will implement unit GDP CO2 emissions 40 % - 45 % lower than in 2005. Therefore, the task of CO2 emissions of coal-fired power plant is significant. The CO,, capture and storage （CCS） technology can reduce power plant emissions by 80 % - 95 % and has enormous potential to reduce emissions in theory. CCS is an important way of CO2 emissions in the world. At present, power plants capture technology is generally divided into three types： pre-combustion capture, post-combustion capture and oxygen-enriched combustion capture.
