中文摘要	中国是煤转化的技术引领者,已建、拟建和审批了大量煤转化企业;随之带来了严峻的CO_2排放和水资源缺乏的问题。CO_2强化深部咸水开采(CO_2-EWR)技术是大规模CO_2减排和水资源开采的方法,特别适合缺水区域的煤化工行业。煤化工企业工艺排放的高浓度CO_2结合CO_2-EWR技术可以较低成本实现CO_2减排,并部分解决工业缺水的问题。研究首先建立了行业尺度的包括源汇匹配、技术经济评价、CO_2排放量评估和封存场地适宜性评价等方法的全流程碳捕集、利用和封存技术经济评估方法(ITEAM-CCUS),然后采用该方法对2018年的煤化工企业排放的高浓度CO_2开展全流程CO_2-EWR项目的源汇匹配、成本范围及减排潜力进行评价并得到:大部分的源汇组合分布在中国西北、华北及北部等干旱地区;基于煤化工厂2018年的实际产量和100%总产能计算,高浓度CO_2年排放量分别是190 Mt和1726 Mt;当全流程CO_2-EWR项目的平准化成本低于200元/t CO_2时,累计CO_2减排量分别为160 Mt/a与1569 Mt/a,地下水产量分别为241 Mt/a与2353 Mt/a。研究结果表明煤化工CO_2-EWR技术是中国煤化工行业低碳可持续发展的关键技术,也为中国部署大规模CCUS提供了低成本机会。
英文摘要	As a leading country in coal chemical technology, a huge number of coal chemical factories are at stages of operating, construction and proposal to administrative system in China. This causes huge problems of CO_2 emissions and water demand. CO_2-enhanced deep saline water recovery (CO_2-EWR) technology can provide large-scale CO_2 mitigation and additional water recovery, especially in coal rich and water scarcity areas. The combination of CO_2 from industrial separation processes in the coal chemical industry and CO_2-EWR technology can provide low-cost opportunities to solve the CO_2 mitigation-water shortage nexus. The study firstly establishes a model of Integrated Techno-Economic Assessment Method for CO_2 Capture, Utilization and Storage (ITEAM-CCUS) in industrial scale which includes source-sink matching, techno-economic assessment, CO_2 emissions assessment, and storage site suitability evaluation. Then assess high concentrations of CO_2 emissions which is captured from China's coal chemical factories of 2018, source-sink matching, and the range of cost and emissions reduction potential of full chains CO_2-EWR projects. The basic evaluation results are that most of the source-sink couplings distribute in dry areas including Northwest China, North China, northern, etc. Annual high concentrations of CO_2 emissions respectively is 190 Mt and 1726 Mt assessing by the actual production in 2018 and the total capacity of coal chemical factories; the annual cumulative CO_2 emission reductions are 160 Mt and 1569 Mt with levelized cost less than 200 CNY/t CO_2, and the corresponding saline water production are 241 Mt and 2353 Mt, respectively. Therefore, CO_2-EWR technology can be essential to low-carbon and sustainable development of the coal chemical industry in China, and may provide low-cost opportunities to spread the large-scale deployment of CCUS technologies in China.
