我国石油天然气行业大气汞排放预测及减排

Atmospheric mercury emission prediction and emission reduction in petroleum and natural gas industry for China

基于2015年我国不同地区原油及天然气产量和区域分布的统计数据,利用联合国环境署确定的汞输入因子和输出因子,估算了我国石油开采、炼制环节以及天然气开采、燃烧环节中大气汞的排放量.同时,依据国家发改委发布的石油天然气发展"十三五"规划中制定的预测性指标,以2015年为基准年,针对2020~2030年期间的石油天然气生产加工行业大气汞排放量设定了3个阶段的减排目标,在此基础上计算了不同阶段内两大行业大气汞的减排量和排放量,为国家实现履行《水俣公约》提供基础数据支撑和参考.

The production and processing of petroleum and natural gas was one of the important sources of atmospheric mercury emission from anthropogenic sources.Based on the statistical data of crude oil and natural gas production and regional distribution in different regions of China in 2015,using the mercury input factor and output factor determined by the United Nations Environment Programme,the atmospheric mercury emissions in China's oil extraction,refining,natural gas extraction and combustion were estimated.Meanwhile,according to the predictive indicators of the 13th five-year plan for oil and gas development released by the national development and reform commission,taking 2015 as the base year,three emission reduction targets were set for the atmospheric mercury emission in the oil and gas production and processing industry from 2020 to 2030,and based on that,the emission and emission reduction of atmospheric mercury in the two major industries were calculated,which could provide basic support for the implementation of Minamata Convention.
