摘　　要：随着我国“双碳”战略稳步推进,从能源消耗总量和强度双控(能耗双控)转向碳排放总量和强度双控(碳排放双控)的新形势对石油石化行业节能减碳提出了更高的要求。本研究从石化产业链的关键环节——炼化生产经营和计划优化的角度出发,探索炼化企业在不改变现有生产工艺和能源结构、不增加额外投资的前提下,通过优化生产方案实现碳减排的新途径。通过梳理某炼化一体化企业A和燃料型企业B的生产过程碳排放情况,创新间接排放因子计算方法,对企业每套装置的碳排放量进行精准测算,将炼油厂的碳排放量测算精度从全厂级别推进到装置级别。并进一步将装置的碳排放量纳入生产计划优化模型,研究了装置级碳排放对企业计划优化的影响,研究发现在原油加工量和乙烯产量等条件不变的情况下优化减碳空间至少3%,为A和B企业在实际生产中提供了切实可行的碳减排解决方案。With the steady progress of“dual-carbon”strategy in China,the new situation of shifting from“dual-control of energy consumption”to“dual-control of carbon emission”has put forward higher requirements for energy conservation and carbon reduction in the petrochemical industry.From the perspective of the key link of petrochemical industry chain-production,operation and planning optimization,this study explored a new way to reduce carbon emission by optimizing production scheme without changing the existing production process and energy structure and increasing additional investment.By combining the carbon emissions from the production process of a refining-chemical integrated enterprise A and a fuel-based enterprise B,and innovating the calculation method of indirect emission factors,the carbon emissions from each set of units of the enterprise was accurately calculated,the accuracy of carbon emissions measurement of refineries was advanced from the whole-plant level to the level of units.Furthermore,the carbon emissions of the plant was incorporated into the production planning optimization model,and the influence of carbon emissions of the plant on the enterprise planning optimization was investigated,and it was found that there was a space for optimizing the carbon reduction of at least 3%under the conditions of no change in the crude oil processing volume and ethylene production,which provided practical solutions for carbon emission reduction of enterprises A and B in the actual production.
