- W2358477505 abstract "Tahe crude oil is a heavy crude oil with high content of asphaltene,carbon residue,metal and high acid value.The corrosion of Tahe crude oil was investigated by the weight loss of hanging slice method.Tahe atmospheric residue after flashing was directly used as the solvent deasphalting raw material in this work.Tahe atmospheric residue was separated into six fractions and the structure parameters of the six fractions were calculated by the modified Brown-Ladner method.The results indicate that53.89% of sulfur,86.97% of nitrogen and more than 98% of Ni and V metals exist in resin and asphaltene.With the deterioration of the fractions,fAincreases,while H/C ratio,fN and HAU/CA decrease.There is a good correlation between the impurity removal rate under different chromatographic effluent yield and the results of solvent deasphalting process in pilot plant,indicating that the chromatographic separation method can be used to predict the impurity content of deasphalted oil with different yield of deasphalting process and to guide the solvent deasphalting process." @default.
