摘要
本文介绍了CO2的捕捉和地质封存技术以及CO2封存后的环境监测技术。CO2捕捉主要包括燃烧前捕捉、燃烧后捕捉、富氧燃烧捕捉。捕捉之后需要将CO2运输到适合的地点进行封存。CO2封存技术主要包括地质封存、深海封存和矿石碳化技术。以地质封存技术为主,基于对其封存方法的分析,详述了不同地质构造(废弃油气田、地下盐水层、废弃煤层)埋存CO2后在地下的状态和不同发展阶段。CO2地下封存完成后,需要长期在地表监测泄漏情况,这也是CCS技术能够成功的关键之一,本文对相关技术的现状与进展进行了介绍。
The aim of the paper presents an overview of CO2 capture and geological storage technologies,and environmental monitoring strategies after storage.CO2 can be captured using one of three systems: pre-combustion,post-combustion,and oxyfuel combustion.After capture,CO2 needs to be transported to appropriate location for sequestration.CO2 storage technologies include geological storage,deep-sea storage and mineral carbonation.Based on analysis of geological storage technologies,the paper mainly introduce CO2 geological sequestration on storage mechanism and different growing phrases of different geological formations(depleted and disused oil and gas fields,deep saline aquifers,and abandoned coal seam).After sequestration,CO2 leakage and seepage as one of the key factors of CCS success shall be monitored for a long time.
