  • Publication number: 20200308496
    Abstract: 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.

  • Publication number: 20200102510
    Abstract: Processes and apparatus for maximizing production of heavy naphtha from a hydrocarbon stream are provided. The process comprises providing a hydrocarbon feed stream comprising vacuum gas oil to a first hydrocracking reactor. The hydrocarbon feed stream is hydrocracked at first hydrocracking conditions comprising a first hydrocracking pressure to provide a first hydrocracked effluent stream therein. At least a portion of the first hydrocracked effluent stream is fractionated in a fractionation column to provide a heavy naphtha fraction. A kerosene stream is hydrocracked in a second hydrocracking reactor operating at second hydrocracking conditions comprising a second hydrocracking pressure to provide a second hydrocracked effluent stream. In an aspect, the first hydrocracking pressure can be greater than the second hydrocracking pressure by at least about 6895 kPa (g).

  • Patent number: 10443001
    Abstract: 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.

  • Publication number: 20190161692
    Abstract: 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.
