管输行业甲烷排放现状与管控对策

The Situation and Management of Methane Emissions in Pipeline Transportation Industry

天然气是一种优质、高效、清洁的低碳能源,但甲烷排放的短期温室效应影响更加显著,是气候变暖的主要因素之一,由此天然气全产业链甲烷排放逐渐成为业界关注的焦点。针对甲烷控排制约管输企业高质量发展,文章论述了甲烷排放对管输企业、天然气价值的影响,通过研究甲烷控排现状,分析了天然气管网在甲烷管控方面存在的主要问题,包括起步发展较晚、基础工作不足、数据核查不准、减排路线不精等问题,并提出了应对措施,加强对甲烷排放管控对策的完善与细化,完善甲烷排放管控的顶层设计,实施甲烷排放监测和核算体系,建立甲烷排放控制标准及规范,优化管网运行方式,加强重点排放源控制和技术研发试验,使用新工艺、新设备减少甲烷排放,推进LDAR风险管理,强化基础研究工作。

Natural gas is a high-quality,efficient and clean low-carbon energy source,however the methane emission during the natural gas industry is more significant in short-term greenhouse effect,and it is one of the main factors of climate warming.As a result,methane emissions from the entire natural gas industry chain have gradually become the industry focus.At the problem that the methane emission control be a bottleneck factor restricting the development of the gas pipeline networks,this paper discussed the impact of methane emissions on the pipeline enterprises and the natural gas value.By studying the current situation of methane emission control,the main problems of methane emission control in nature gas pipeline networks were analyzed,including the late start development,insufficient basic work,inaccurate data verification and imprecise emission reduction route.The control countermeasures were proposed,such as strengthen the improvement and refinement of methane emission control measures,improve the top-level design of methane emission control,implement methane emission monitoring and accounting system and establish methane emission control standards and norms.Also,the operation mode of pipeline network should be optimized,the key emission sources control and technology research tests be strengthened,the new processes and equipment be used to reduce methane emission,following with the promotion of LDAR risk management and strengthen of the basic research work.
