  • Patent number: 7919054
    Abstract: Disclosed are a process and an installation for treatment of a heavy petroleum feedstock, of which at least 80% by weight has a boiling point of greater than 340° C., wherein the process includes (a) hydroconversion in a boiling-bed reactor operating with a rising flow of liquid producing a hydroconversion effluent; (b) separation of hydroconversion effluent into a gas containing hydrogen and H2S, a fraction comprising gas oil, and a naphtha fraction; c) hydrotreatment, by contact with at least one catalyst, of at least said fraction comprising gas oil, producing a hydrotreatment effluent; and d) separation of hydrotreatment effluent into a gas containing hydrogen and at least one gas oil fraction having a sulfur content of less than 50 ppm, wherein the hydrogen supply for the hydroconversion and hydrotreatment is delivered by a single compression system.

  • Publication number: 20080093262
    Abstract: This invention relates to a process and an installation for treatment of a heavy petroleum feedstock, of which at least 80% by weight has a boiling point of greater than 340° C., whereby the process comprises the following stages: (a) Hydroconversion in a fixed-bed reactor operating with an upward flow of liquid and gas, whereby the net conversion in products boiling below 360° C.

  • Publication number: 20080083652
    Abstract: The invention relates to a process for conversion of a heavy feedstock that has a boiling point of more than 340° C. for at least 80% by weight of the feedstock, a Conradson carbon content of at least 5% by weight, an asphaltene content of at least 1% by weight, a sulfur content of at least 0.5% by weight, and a metal content of at least 20 ppm, process in which: Said feedstock is subjected to deasphalting, and a deasphalted oil that contains less than 1% by weight of asphaltenes is obtained At least a portion of said oil, and preferably all of it, is subjected directly to hydroconversion in the presence of a supported or dispersed catalyst, and the effluent that is obtained is distilled to separate a residue At least part if not all of said residue is recycled with the feedstock to deasphalting.
