CO_2 Capture and Resource Recovery Technologies for Coal-fired Power Plants

温室气体CO2的减排问题已经引起了国际社会的极大关注。针对于CO2的集中排放源,介绍了火力发电厂各种CO2分离捕集技术的发展现状。直接从火力发电厂的烟气中分离并捕集CO2,然后对其进行储存或加以利用,是目前控制和减缓温室气体排放的重要措施之一。基于经济可行性,还介绍了包括EOR在内的各种CO2资源化技术,并展望了CO2减排技术的发展前景。

The international societies have paid great attention to the mitigation of the greenhouse gas CO2. The development status of technologies for separate and capture of CO2 from coal-firod power plants is introduced, which are the important emission fountains of CO2. Separating and capturing CO2 directly from the coal-fired flue gas and then depositing or making use of it is one of the important measures to control and reduce the emission of greenhouse gas. Based on the economy feasibility, the CO2 resource technologies are also intrgduced including the EOR technology, and the development foreground vista of CO2 mitigation is shown.
