Evaluation on comprehensive properties of crude oil imported from Russian
The imported Russian crude oil was cut by using a true boiling point distiller,and the re-sulting fractions were analyzed and compared with crude oil from Yulin of Shaanxi Province with known properties to obtain comprehensive evaluation data for the imported Russian crude oil.The results showed that compared with Yulin crude oil,the light oil fraction of imported Russian crude oil had a higher yield and belonged to the intermediate base crude oil according to the key fraction classification.The 15-175℃fraction was a high-quality ethylene cracking feedstock after refining.The 65-175℃fraction could be used as a catalytic reforming feed-stock,and the 140-240℃fraction could produce No.3 jet fuel.The 175-370℃fraction could produce-20#motor diesel,the 240-360℃fraction could produce-10#motor diesel,the 360-500℃fraction could produce lubricating oil base oil raw materials with low viscosity index requirements after dewaxing and refining,and the 360-540℃fraction was a general catalytic cracking feedstock.The heavy oil fraction above 360℃belonged to the second type of residual oil,which could be partially blended into wax oil as catalytic cracking feedstock,and the residual oil fraction above 540℃belonged to the third type of residual oil,which could be used as delayed coking feedstock.
