二氧化碳地质封存联合深部咸水开采技术进展

 CO₂捕集、利用与封存(CCUS)技术具有很大的发展前景,而CO₂地质封存联合深部咸水开采技术(简称CO₂驱水技术,CO₂-EWR)作为一种新型的CCUS技术,可在实现CO₂深度减排的同时缓解水资源紧缺现状,对于以煤为主要能源结构的中国来说,是一种确保国家能源安全的双赢选择。根据中国含水层系统类型,中国陆地可大致划分为3个CO₂-EWR利用分区,考虑到该技术的研发程度及成本预测,西部地区的煤电煤化工企业具有早期机会,因此本文主要针对西部地区煤化工企业(一区)展开分析与评价。概述了CO₂-EWR技术的概念、意义及研究现状,探讨了其技术链条中各要素技术,展望了CO₂-EWR技术的前景及重要发展方向。

Progress in Combination of CO2 Geological Storage and Deep Saline Water Recovery

CO₂ capture, utilization and storage(CCUS) shows very a charming development prospect in China. CO₂ geological storage combined with deep saline water recovery (CO₂-EWR), as a new CCUS technology which not only achieves deep emission reduction, but also alleviates the water shortage situation, is no doubt a win-win choice ensuring national energy security for China's energy structure with coal. China mainland can be partitioned into three potential CO₂-EWR zones mainly according to the different types of aquifer system. Considering Research and Development(R & D) maturity and cost prediction of the technology, coal power and coal chemical enterprises in the western region has an early opportunity, so analysis and evaluation mainly focus on coal chemical industry in the western China (Zone One) in this study. CO₂-EWR technical elements in the full chain technology are discussed on the basis of outline of CO₂-EWR concept, significance and overview of latest research, and finally CO₂-EWR technology development and important implementation direction are pointed out.
