摘要

炼油行业的低碳化转型对国家“双碳”目标的实现具有重要意义。以某“燃料型”炼油企业为研究对象，采用排放系数法和物料衡算法对其基准年碳排放量进行了核算，并基于核算结果分析了碳排放源项分布特征。此外，借助情景分析法，预测了在中度管控（MC-CE）和深度管控（DC-CE）两种情景下的碳排放趋势，并评估了8项减碳措施在不同情景下的碳减排潜力。结果表明，该炼油企业基准年的碳排放总量为71.7683 × 10

t/a，平均碳排放因子（单位原油加工量碳排放）为0.2691 t/t，其中燃料燃烧和催化剂烧焦为主要碳排放源。在MC-CE情景下，2030年和2040年的碳排放量分别较基准年下降18.84%和28.80%；而在DC-CE情景下，2030年和2040年的碳排放量较基准年分别下降37.08%和53.59%。基于研究结果，建议炼油企业加快节能改造步伐，积极引进低碳技术，并大力推广清洁能源应用，以推动低碳转型进程。

Abstract

The low-carbon transformation of the oil refining industry is crucial to achieving “carbon peaking and carbon neutrality” goal. A “fuel-based” refinery was taken as the research object

and the emission factor method and the material balance method were adopted to calculate its carbon emission in the base year

and the distribution characteristics of carbon emission sources were analyzed based on the accounting results. Furthermore

using the scenario analysis method

carbon emission trends under medium control (MC-CE) and deep control (DC-CE) scenarios were predicted

and the carbon reduction potential of eight mitigation measures under different scenarios was evaluated. The results show that the refinery’s total carbon emission in the base year is 71.7683 × 10

t/a

with an average carbon emission factor (carbon emissions per unit of crude oil processed) of 0.2691 t/t. Fuel combustion and catalytic coking are identified as the primary sources of carbon emissions. Under the MC-CE scenario

carbon emissions in 2030 and 2040 are projected to decrease by 18.84% and 28.80%

respectively

compared to the base year

. Under the DC-CE scenario

carbon emissions in 2030 and 2040 are expected to decline by 37.08% and 53.59%

respectively

compared to the base year. Based on the research findings

it is recommended that refineries accelerate energy-saving retrofits

actively introduce low-carbon technologies and vigorously promote the application of clean energy to facilitate the low-carbon transition.
