Abstract:
Apparatus for upgrading a hydrocarbon reed containing sulfur, metals, and asphaltenes, said apparatus comprising:a) a distillation column for receiving said feed and producing a substantially asphaltene-free, and metal-free distillate fraction and a non-distilled fraction containing sulfur, asphaltene and metals;b) means for producing a hydrogen donor diluent from at least some of said substantially asphaltene-free, and metal-free distillate tract on;c) a solvent deasphalting unit for processing said non-distilled fraction and producing a deasphalted oil stream and an asphaltene stream, an outlet of said solvent deasphalting unit containing said deasphalted oil being connected to an inlet of a thermal cracker, and an outlet of said means for producing hydrogen donor diluent containing said hydrogen donor diluent being connected to the inlet of said thermal cracker; andd) said thermal cracker thermally cracking said deasphalted oil in the presence of said hydrogen donor diluent and forming a thermally cracked stream, an outlet of said thermal cracker being connected to an inlet of said distillation column and supplying said thermally cracked stream to said distillation column.
