METHOD OF AND APPARATUS FOR PROCESSING HEAVY HYDROCARBONS

摘要

A fractionating solvent deasphalting plant applies a solvent whose critical temperature is T c to a hydrocarbon feed containing asphaltenes and atmospheric distillate having fractions that boil above about T c-50 .degree.F. such that said feed is separated into a substantially solvent-free product stream of atmospheric distillate, a substantially solvent-free product stream containing deasphalted oil substantially free of said atmospheric distillate, and a substantially solvent-free product stream containing asphaltenes substantially free of said atmospheric distillate.
