摘要:

目前全球气候变暖已是不争的事实,二氧化碳排放控制技术正受到越来越多的关注。本文全面介绍了近期国内外燃煤电厂二氧化碳捕集封存与利用技术的研究进展,对以氨水作为吸收剂的化学吸收法、二氧化碳碳化封存技术以及二氧化碳捕集与矿化封存一体化技术做了重点介绍和客观评价。其中,二氧化碳捕集与矿化封存一体化的新工艺,可以克服以往工艺能耗高、效率低的缺点,同时还能生产有经济价值的副产品来降低CCS的成本,有着良好的发展前景。

Abstract:

As global warming worsens, carbon dioxide emissions control technology attracts more and more attention. This paper introduces the development of carbon dioxide capture,utilization and storage technology in domestic and oversea countries. Then give main attention and evaluation to the technology of carbon dioxide capture using aqueous ammonia solution, carbon dioxide storage by mineralization, and a novel process integrating carbon dioxide capture with mineralization. The integrative process is a promising technology to overcome the barriers of high energy penalty and low efficiency, and produce high value byproducts to decrease the cost of CCS.
