摘要
近年来我国能源化工行业稳步发展,原料用能在我国能源消费中的占比持续提升。但由于原料用能相关碳排放环节复杂,一直是碳排放核算工作中的难点。本文在分析我国能源化工行业的发展现状及面临挑战的基础上,按照IPCC计算方法分产品、分工艺确定典型能源化工产品原料用能碳排放因子,自下而上核算能源化工行业原料用能碳排放量,并提出原料用能碳排放核算相关建议。研究发现,不同能源化工产品原料用能碳排放因子差异较大,约在0.05~7.2 tCO_(2)/t之间,煤化工产品工业过程碳排放因子普遍高于石油化工和天然气/轻烃化工产品;2022年,我国能源化工行业原料用能碳排放为53319万吨,约占我国与能源相关碳排放总量的4.4%。为做好原料用能碳排放统计核算,需加快夯实原料用能相关数据统计的基础,建立完善重点产品工业过程碳排放因子数据库,并做好原料用能统计口径与碳排放核算口径的衔接工作。
In recent years,China's energy and chemical industry has been developing steadily,and the share of feedstock energy use in China's energy consumption has been increasing.However,due to the complexity of carbon emission links related to feedstock energy use,it has always been a difficult point in carbon emission accounting.Based on the analysis of the development status and challenges of China's energy and chemical industry,this paper determines the carbon emission factors of typical chemical products in industrial processes according to the IPCC calculation method,calculates the carbon emissions of feedstock energy use from the bottom up,and puts forward the relevant suggestions on carbon emissions accounting of feedstock energy use.It is found that the carbon emission factor of typical chemical products in industrial processes ranges from 0.05 to 7.2 tCO_(2)/t,and China's carbon emission from feedstock energy use in 2022 will be 533.19 million tons,accounting for about 4.4%of China's total carbon emission.In order to do a good job in the statistical accounting of carbon emissions from feedstock energy use,it is necessary to accelerate the consolidation of the statistical basis of data related to feedstock energy use,establish and improve the database of carbon emission factors of key products in industrial processes,and do a good job of convergence between the statistical caliber of feedstock energy use and the caliber of carbon emission accounting.
