摘要： An integrated process for maximizing recovery of hydrogen is provided. The process comprises: providing a hydrocarbonaceous feed comprising naphtha, and a hydrogen stream to a reforming zone, wherein the hydrogen stream is obtained from at least one of a hydrocracking zone, a transalkylation zone, and an isomerization zone. The hydrocarbonaceous feed is reformed in the reforming zone in the presence of the hydrogen stream and a reforming catalyst to provide a reformate effluent stream. At least a portion of the reformate effluent stream is passed to a debutanizer column of the reforming zone to provide a net hydrogen stream and a fraction comprising liquid petroleum gas (LPG). At least a portion of the net hydrogen stream is recycled to the reforming zone as the hydrogen stream.

摘要： A process and apparatus for reducing the sulfur content of naphtha. The process includes introducing at least a portion of a naphtha feed stream to a selective hydrodesulfurization zone under selective hydrodesulfurization conditions in the presence of a selective hydrodesulfurization catalyst to form a low sulfur stream which contains mercaptan and thiophene compounds. At least a portion of the low sulfur stream is separated into at least two streams, a mercaptan rich stream containing mercaptan and thiophene compounds and an overhead stream containing hydrogen sulfide and liquid petroleum gas. The mercaptan rich stream is treated in an adsorbent zone to remove at least a portion of the mercaptan and thiophene compounds to form a mercaptan lean stream.

摘要： A process and apparatus for increasing vacuum gas oil recovery from a vacuum column are described. The process includes separating a residue crude oil stream from a crude oil separation column in a vacuum column into at least one vacuum gas oil fraction, and a contaminant-rich slop fraction containing at least one contaminant; contacting the contaminant-rich slop fraction with a lean ionic liquid in a contaminant removal zone to produce a mixture comprising a contaminant-lean slop fraction and a rich ionic liquid comprising at least a portion of the at least one contaminant; and separating the mixture to produce a treated slop effluent comprising the contaminant-lean slop fraction and a rich ionic liquid effluent comprising the rich ionic liquid.

摘要： Methods and apparatuses are disclosed for upgrading a hydrocarbon feedstream comprising passing the hydrocarbon feedstream to a first hydroprocessing reactor in a reaction vessel to produce a first hydroprocessed effluent stream. The first hydroprocessed effluent stream is separated in a hot separator to produce a vapor stream and a liquid hydrocarbon stream. At least a portion of the liquid hydrocarbon stream is passed to a second hydroprocessing reactor disposed in the reaction vessel above the first hydroprocessing reactor, to produce a second hydroprocessed effluent stream. A liquid product stream is separated from the second hydroprocessing effluent stream. The vapor stream from the hot separator is mixed with the liquid product stream to provide a combined stream.

摘要： An integrated process for maximizing recovery of LPG is provided. The process comprises providing a hydrocarbonaceous feed comprising naphtha, and a hydrogen stream to a reforming zone. The hydrocarbonaceous feed is reformed in the reforming zone in the presence of the hydrogen stream and a reforming catalyst to provide a reformate effluent stream. At least a portion of the reformate effluent stream and at least one stream comprising C6− hydrocarbons from one or more of a hydrocracking zone, an isomerization zone, and a transalkylation zone is passed to a debutanizer column of the reforming zone to provide a fraction comprising liquid petroleum gas (LPG) and a debutanizer column bottoms stream.

摘要： Processes for the production of a gasoline blend. A C7 portion of a naphtha stream is first isomerized to increase the branched, iso-paraffins, and then, the isomerized effluent is passed to a dehydrogenation reaction zone. In the dehydrogenation zone, the C7 saturated hydrocarbons are convert to C7 olefins. The C7 olefins have a higher octane number than the C7 saturated hydrocarbons, and the branched olefins have a higher octane number than the normal olefins. The C7 olefins can be blended in a gasoline pool. C5 and C6 hydrocarbons can be isomerized and dehydrogenated as well, separately or with the C7 components.
