摘要
全球气候变化问题日益严重,CO2捕集与封存(CCS)技术被看作是最有发展前景的解决该问题的技术之一。CCS技术主要包括3个环节:CO2捕集,运输和封存。首先介绍了CO2捕集技术,该技术按工艺主要分为燃烧前捕集、富氧燃烧捕集、燃烧后捕集和化学链燃烧捕集。随后介绍了CO2封存技术,该技术按封存地点可分为地质封存和海洋封存。在众多的CO2封存技术中,CO2强化采油技术由于其较高的经济效益近年来得到广泛应用。从国外、国内两个层面详细介绍了该技术的发展情况。
Carbon dioxide capture and storage(CCS) technology is seen as one of the most promising solutions to global climate change.The CCS technology mainly includes three aspects: CO2 capture,transport and storage.Firstly,this paper introduces the CO2 capture technology,which can be categorized into pre-combustion capture,enriched oxygen combustion capture,post-combustion capture and chemical looping combustion capture;then the paper introduces the CO2 storage technology,which can be categorized into geology storage and ocean storage according to storage site.Among many CO2 storage technologies,CO2 enhanced oil recovery(CO2-EOR) technology has been widely used in recent years with its high economic benefits;finally the paper describes the domestic and international development of the CO2-EOR technology in detail.
