近地表高浓度CO_2泄漏监测体系构建的探讨

Discussion about Constructing Monitoring System of High Concentration of CO_2 Leakage near Surface

碳捕集与封存技术(CCS技术)主要包括CO_2的捕集、运输以及封存等关键环节,但在CO_2的地质封存方面存在着CO_2大规模泄漏的风险,使得该技术在实际应用方面对环境和社会存在着不可估量的威胁,所以解决CO_2泄漏的问题非常重要。本文讨论了对CO_2泄漏的直接监测和间接监测,直接监测包括了遥感监测、激光雷达监测、仪器监测,间接监测有农作物监测、动物监测以和土壤离子浓度监测,以此来构建进地表高浓度CO_2泄漏的监测体系,对CCS技术在我国的进一步推广和发展提供技术参考。

CCS technology is a new technology aims at cutting down the CO_2 in the world,which mainly includes capture,transportation and sequestration of CO_2. But there is a big risk produced in the leakage of CO_2 sealed under the ground,which restricts the CCS technology to progress and be applied. So it is important to monitor the leakage of the CO_2. This paper is about direct and indirect monitoring of the CO_2 leakage. Direct monitoring includes remote sensing and laser radar monitoring,and indirect monitoring includes crop,animal and soil ions monitoring. We can use the different monitoring ways to construct a monitoring system to realize the CCS technology's further promotion and development.
