城镇燃气行业甲烷减排的关键路径研究

Research on Key Path of Methane Emission Reduction in Urban Gas Industry

甲烷是仅次于二氧化碳的全球第二大温室气体,但相同单位的甲烷产生的变暖潜势约为二氧化碳的25倍。城镇燃气行业生产运营过程中,甲烷的泄漏和排放将削弱天然气替代煤炭带来的气候效应。甲烷排放的有效管控是发展天然气作为绿色低碳能源的重要前提。本文结合城镇燃气行业甲烷减排的现状与意义,分析甲烷泄漏原因和甲烷排放监测技术,最后指出关键减排路径,以推进城镇燃气行业甲烷减排。

Methane is the second largest greenhouse gas in the world after carbon dioxide,but the warming potential of the same unit of methane is about 25 times that of carbon dioxide.During the production and operation of urban gas industry,methane leakage and emission will weaken the climate effect of natural gas replacing coal.Effective control of methane emissions is an important prerequisite for the development of natural gas as a green and low-carbon energy.Based on the current situation and significance of methane emission reduction in urban gas industry,this paper analyzes the causes of methane leakage and methane emission monitoring technology,and finally points out the key emission reduction path to promote methane emission reduction in urban gas industry.
