摘要
近年来,许多国家(地区)开展钢铁工业CO_2捕捉与封存(CCS)技术研究。在CCS成本中,CO_2捕捉成本约占70%,因此,降低CO_2捕捉成本是CCS首先要解决的问题。目前钢厂开发的CO_2捕捉工艺主要以化学吸收法和物理吸附法为主,并在试验规模取得成本降低的效果。介绍日本新日铁和JFE、韩国浦项、中国台湾中钢等开发的CO_2捕捉技术,并对CO_2捕捉技术的工业化应用前景进行分析。
The iron and steel industries in several countries（regions） have been carried out the development of carbon capture and sequestration（CCS）technology in recent years. The carbon dioxide capture cost approximately accounts for 70 percent of the total cost of CCS. Therefore,the reduction of the cost to capture the carbon dioxide becomes the major problem. The carbon dioxide capture processes developed by the steel works so far are mainly chemical absorption methods and physical adsorption methods,the costs in experimental scale have been reduced. The carbon dioxide capture technologies developed by Japanese steel works,such as Nippon Steel and Sumitomo Metal,South Korea＇s POSCO and ChinaTaiwan＇s China Steel etc are described and the industrial application potentials of the technologies are analyzed.
