Abstract (en)
[origin: WO2018152512A1] Embodiments provide a method and apparatus for upgrading a hydrocarbon feedstock. According to at least one embodiment, the method includes (a) supplying a hydrocarbon feedstock to an oxidation reactor, where the hydrocarbon feedstock is oxidized in the presence of a catalyst under conditions sufficient to selectively oxidize sulfur compounds present in the hydrocarbon feedstock; (b) separating the hydrocarbons and the oxidized sulfur compounds by solvent extraction; (c) collecting a residue stream that includes the oxidized sulfur compounds; (d) supplying the residue stream to a coker to produce coker gases and solid coke; and (e) recycling at least a portion of the volatile component stream to the oxidation reactor to selectively oxidize sulfur compounds in the volatile component stream, the recycled portion of the volatile component stream comprising at least one of light coker gas oils and heavy coker gas oils.
