陆上石油天然气开采过程中减污降碳协同管控

Collaborative control of pollution and carbon reduction in the process of onshore oil and gas exploitation

  • 摘要: 石油天然气行业是挥发性有机物(VOCs)排放的重要源头,也是甲烷(CH4)的最大工业释放源。在石油天然气开采中对VOCs与CH4进行协同管控,实现减污降碳,对我国大气环境治理和“双碳”目标实现具有重要意义。石油天然气开采过程中大部分VOCs和CH4释放源具有同根同源性,其中工艺有组织排放和火炬排放分别为最大的VOCs释放源和CH4释放源;在加入新型网络化监测的协同管控路径基础上,选择适宜的管控措施,可提高污染物协同管控的效率;治理成本效益核算中多污染物成本效益法具有更高的经济效益,吸收法和吸附法是技术成熟度和经济性较高的VOCs治理技术,而减少压缩机和发动机启动次数是最经济的CH4减排措施。

     

    Abstract: The oil and gas industry is an important source of volatile organic compounds (VOCs) emissions and the largest industrial release source of methane (CH4). The coordinated control of VOCs and CH4 in oil and gas exploitation to achieve pollution reduction and carbon reduction is of great significance to China's atmospheric environmental governance and the realization of the "double carbon" goal. Most of the VOCs and CH4 emission sources in the process of oil and gas exploitation have the same root homology, and the organized emission of processes and the torch emission are the largest VOCs emission source and CH4 emission source, respectively. On the basis of adding the collaborative control path of new networked monitoring, selecting appropriate control measures can improve the efficiency of collaborative control of pollutants. The multi-pollutant cost-benefit method in the cost-benefit accounting of pollution control has higher economic benefits. The absorption method and adsorption method are VOCs treatment technologies with higher technical maturity and economy, and reducing the number of compressor and engine start-ups is the most economical CH4 emission reduction measure.
