Abstract: 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.

Key words: transformation into a featured refinery, environmentally friendly aromatic-based rubber plasticizer, crude oil, process scheme
