油气管道行业甲烷减排量化分析OA

Exploring and quantifying methane emissions from the oil and gas sector,which is the main source of methane emissions,it underscores the importance of accurately exploring and quantifying these emissions in order to facilitate the ambitious goals of achieving a"carbon peak"by 2030 and attaining"carbon neutrality"by 2060.In order to accelerate the research of methane emission measurement and estimation in Chinese oil and gas system,this paper presents a quantitative case of methane emission from long distance natural gas pipeline,conducts in-depth investigation on some methane emission data of a company,determines methane emission by combining sample method and activity level,and finally predicts the methane emission reduction generated by six emission reduction technologies.By comparing the methane emissions before and after the use of emission reduction technology in the system,it is found that after fully applying the emission reduction technology,the annual methane emissions of the system are 409 043.644 Nm3/a,and the emission reduction effect can reach up to 94.453％.In this paper,this method is applied for the first time to quantify methane emission reduction in long distance natural gas pipelines,which will have a far-reaching impact on the oil and gas industry to reach the"two-carbon"goal as soon as possible.
