甲烷排放检测技术应用现状综述

Introduction of Technologies and Application of Methane Emission Monitoring

通过分析甲烷排放检测与量化测定需要注意的两方面问题,指出油气行业甲烷排放量检测不准确问题的关键在于提高检测仪器的精度和采样的精度(包括时间与空间因素)。对目前油气行业甲烷排放检测设备包括成像相机和路径集成传感设备、大气甲烷采样器、遥感卫星等进行梳理,较为系统地介绍了各类检测技术和设备的原理和特点,以及部分技术的实际应用效果和应用中遇到的问题。为下一步在我国开展全面系统的甲烷排放检测工作提供了技术支持。

This study analyzes monitoring and quantification of methane emission,and points out the key issue to improve low accuracy of methane emission data in oil and gas industry is to increase the accuracy of sampling and accuracy of monitoring devices(both in time and space dimensions).This study has also systematically introduced the mechanisms and characters of various kinds of monitoring technologies and devices,including imaging cameras,path integrated sensors,ambient methane samplers,satellite based instruments etc.Moreover,it also introduces practical application effects and challenges of these technologies and devices.In sum,the study provides useful information to China's national-wide methane emission programs.
