CO_(2)捕集封存技术的应用与安全发展研究

Research on Application and Development of CO_(2)Capture and Storage Technology

随着人类对化石燃料使用的依赖,大气CO_(2)含量持续上升,所带来的环境问题已严重影响人类正常的生产与生活。采用CO_(2)捕集封存技术(Carbon Dioxide Capture and Storage,CCS)可以有效的分离出排放源中的CO_(2)气体,并将其输送到封存地点进行封存,这是目前可以有效大规模减少大气CO_(2)含量的技术措施之一。本文通过对CCS技术捕集、运输、封存3个环节的技术方法比较,归纳出各种方法的优缺点。结合目前CO_(2)的主要排放源与主要封存地点现场情况,选择合理方法构建出燃煤电厂与煤矿之间的CCS系统,更方便快捷的实现CO_(2)捕集封对于更具体的了解CO_(2)捕集封存具有指导意义,为降低大气CO_(2)含量提供理论依据和技术指导。

With the dependence of human beings on the use of fossil fuels,the atmospheric CO_(2)content continues to rise,and the environmental problems brought about have seriously affected human normal production and life.The CCS(Carbon Dioxide Capture and Storage)technology can effectively separate the CO_(2)gas from the emission source and transport it to the storage site for storage,which is one of the technical measures that can effectively reduce the atmospheric CO_(2)content on a large scale.This article summarizes the advantages and disadvantages of various methods by comparing the technical methods of CCS capture,transport,and storage.Combining the current main emission sources of CO_(2)and the site conditions of the main storage sites,reasonable methods were chosen to construct the CCS system between coal-fired power plants and coal mines,and CO_(2)capture and storage would be more convenient and faster.The study has guiding significance for more specific understanding of CO_(2)capture and storage and provides theoretical basis and technical guidance for reducing atmospheric CO_(2).
