摘　　要：为优选“双碳”目标约束下含油污泥处理最佳工艺,文章从综合能耗和碳排放强度两个维度对4种典型含油污泥处理工艺进行评估。基于联合国政府间气候变化专门委员会(IPCC)提供的碳核算模型,提出用于石油石化行业含油污泥碳排放量核算方法,分别计算了落地油泥、清罐底泥和气浮浮渣3类含油污泥处理过程的综合能耗和碳排放量。结果表明:罐底油泥选用热洗+热脱附工艺或热洗+微生物降解工艺综合能耗和碳排放强度较低,落地油泥选用热洗+微生物降解工艺或热脱附工艺的综合能耗和碳排放强度较低,气浮浮渣选用热干化+焚烧工艺或热脱附工艺的综合能耗和碳排放强度较低。To optimize the best process for treating oily sludge under the constraints of the“dual carbon”goals,this article evaluates four typical oily sludge treatment processes from the perspectives of comprehensive energy consumption and carbon emission intensity.Utilizing the carbon accounting model provided by the Intergovernmental Panel on Climate Change(IPCC),a carbon emission accounting method tailored for the oily sludge in the petroleum and petrochemical industry is proposed.The comprehensive energy consumption and carbon emissions were calculated for three types of oily sludge:tank bottom sludge,residual sludge from tank cleaning,and air flotation scum.The results indicate that for tank bottom sludge,the combination of thermal washing and thermal desorption or thermal washing and microbial degradation processes results in lower comprehensive energy consumption and carbon emission intensity.For residual sludge from tank cleaning,the thermal washing combined with microbial degradation or thermal desorption processes yields lower energy consumption and carbon emissions.For air flotation scum,the thermal drying combined with incineration or thermal desorption processes shows lower comprehensive energy consumption and carbon emission intensity.
