“燃料-润滑油”型炼油厂“油转特”方案研究

SCHEME RESEARCH ON REFINERY FEATURED TRANSFORMATION OF FUEL-LUBRICATING OIL TYPE REFINERY

基于由糠醛精制抽出油生产环保型芳烃基橡胶增塑剂的可行性,为某10 Mt/a“燃料-润滑油”型炼油厂探索“油转特”转型方案,从全厂总流程角度出发设计了包含利用润滑油基础油糠醛精制抽出油生产环保型芳烃基橡胶增塑剂的“油转特”优化方案。采用该“油转特”方案测算结果表明:成品油收率由62.7%下降至50.7%,船用燃料油收率由4.3%增加至6.6%,润滑油基础油及工业白油收率由6.1%增加至7.9%,环保型芳烃基橡胶增塑剂产品产率为0.25%,特种产品产率为1.74%,说明该“油转特”方案的成品油产量降低,特色产品产量增加,达到了“油转特”的目的。

Based on the feasibility of producing environmentally-friendly aromatic-based rubber plasticizers from furfural extraction oil,the featured transformation program was explored for a 10 Mt/a“fuel-lubricant”refinery.From the point of view of the whole plant process,the optimization scheme was designed,which included the production of environmentally-friendly aromatic-based rubber plasticizer by using furfural refined oil of lube base oil.The calculation results of the featured transformation scheme showed that the yield of refined oil decreased from 62.7%to 50.7%,the yield of low sulfur marine oil increased from 4.3%to 6.6%,the yield of lube base oil and industrial white oil increased from 6.1%to 7.9%,the yield of environmentally-friendly aromatic-based rubber plasticizer products was 0.25%,and the yield of special products was 1.74%,which showed that the output of refined oil in the featured transformation program was reduced,the output of characteristic products was increased,and the aim of featured transformation of the refinery was achieved.
