    摘要: An improved delayed coking process utilizing a coking unit and a coking unit product fractionating column which includes the steps of: heating a mixture of a fresh whole crude oil feedstream and the bottoms from the coking unit product fractionator in a furnace to a coking temperature in the range of 480° C. to 530° C./896° F. to 986° F.; introducing the heated mixed whole crude oil and bottoms feedstream directly into the delayed coking unit; optionally passing the vaporized liquid and gaseous coking unit product stream into a flash unit; recovering a light product gas stream that includes H2S, NH3 and C1 to C4 hydrocarbons from the flash unit; transferring the bottoms from the flash unit to the coking unit product fractionating column; recovering as separate side streams from the fractionating column naphtha, light gas oil and heavy gas oil; recycling a portion of the heavy gas oil by introducing it into the fractionating column optionally with the bottoms from the flash unit; mixing the fractionating column bottoms with the whole crude oil feedstream to form the mixed feedstream; and introducing the mixed whole crude oil and fractionating column bottoms feedstream into the furnace.

    摘要: A crude oil feedstream is treated to remove or reduce the content of known undesired heteroatomic and polynuclear aromatic compounds containing nitrogen and sulfur by contacting the feedstream with one or more solid adsorbent materials selected from attapulgus clay, alumina, silica gel and activated carbon in a mixing vessel for a time that is sufficient to optimize the adsorption of the undesired compounds from the crude oil, subjecting the mixture to atmospheric flash distillation and then to vacuum flash distillation to recover presorbed boiling ranges of products having a lowered content of the undesired compounds, and preferably regenerating at least a portion of the solid adsorbent material for reuse in the process.

    摘要: A hydrocracking process for treating a first and a second heavy hydrocarbon feedstream, in which the first heavy hydrocarbon feedstream contains undesired nitrogen-containing compounds, sulfur-containing compounds and poly-nuclear aromatic compounds. The process includes contacting the first heavy hydrocarbon feedstream with adsorbent material to produce a hydrocarbon stream having a reduced content of nitrogen-containing, sulfur-containing compounds and poly-nuclear aromatic compounds. The second heavy hydrocarbon feedstream is combined with the adsorbent-treated heavy hydrocarbon stream. The combined stream is charged to a hydrocracking reaction unit. The hydrocracked effluent is fractioned to recover hydrocracked products and a bottoms stream containing heavy poly-nuclear aromatic compounds, and bottoms are contacted with adsorbent material to produce an adsorbent-treated fractionator bottoms stream having a reduced content of heavy poly-nuclear aromatic compounds, and are recycled to the hydrocracking reaction unit.

    摘要: A system and process for desulfurizing a hydrocarbon feed stream containing organosulfur compounds is provided. In general, the system includes a conventional hydrotreating unit through the high pressure cold or hot separator. Aqueous oxidant and an oxidative catalyst are mixed with the hydrotreated hydrocarbon effluent from the high pressure cold or hot separator, and oxidative desulfurization reactions occur in the low pressure separation zone, thereby minimizing or eliminating the requirement of additional oxidative desulfurization reactors.
