A process for producing cracked hydrocarbons from a feedstock, which includes a top portion that boils below 375° C. and a bottom portion that boils above 375° C., may include stripping the feedstock in a stripper to isolate the top portion from the bottom portion, hydrocracking the bottom portion in one or more hydrocracking reactors to produce a hydrocracked effluent, separating the hydrocracked effluent in a separating unit to produce a light product stream, a distillate stream, and a heavy unconverted stream; and recycling the heavy unconverted stream to an earlier stage of the process.

A processing facility is provided that includes a feedstock separation system configured to separate a feed stream into a lights stream and a heavies stream, a hydrogen production system configured to produce hydrogen and carbon dioxide from the lights stream, and a carbon dioxide conversion system configured to produce synthetic hydrocarbons or the carbon dioxide. The processing facility also includes a hydroprocessing system configured to process the heavies stream, and a hydroprocessor separation system configured to separate a hydroprocessing system effluent into a separator tops stream and a separator bottoms stream, wherein the separator bottoms stream is fed to the hydrogen production system.

A method comprising the steps of feeding condensate to a splitter unit; directing the resulting naphtha product to a naphtha hydrotreater and the resulting diesel product to a diesel hydrotreater; directing ULSD product from the diesel hydrotreater to ULSD storage and naphtha product from the diesel hydrotreater to the naphtha hydrotreater; directing treated naphtha product from the naphtha hydrotreater to a naphtha splitter; isomerizing the light naphtha product and reforming the heavy naphtha product; sending the isomerate and the reformate to a gasoline separator; directing the products to storage.

The present invention relates to a process for production of anisotropic coke from a hydrocarbon feedstock and a system for producing the same. More particularly, the present invention relates to a thermal cracking of heavy petroleum residue producing petroleum coke and lighter hydrocarbon products. The invented process utilizes a novel scheme for production of a premium quality coke from primarily, a clarified oil feedstock. Clarified oil from fluid catalytic cracking unit is routed through a process scheme comprising a separator column, hydrotreatment section and an aromatic extraction section to create an ad-mix of effluents which form the feedstock to a thermal cracking unit. Premium quality anisotropic coke is produced in the thermal cracker reactor drums under tailor made process conditions employing the said feedstock.

The invention relates a process for the catalytic hydrotreating of a feedstock of petroleum origin of diesel fuel type introduced into a stationary bed hydrotreating unit upstream of a feedstock of natural occurring oil(s) characterized in that the feedstock of natural occurring oil(s) contains acyl-containing compounds having 10 to 24 carbons including fatty acid esters and free fatty acids and said feedstock of natural occurring oil(s) is submitted to a refining by a hydrodynamic cavitation before its introduction into the stationary bed processing.

Process scheme configurations are disclosed that enable conversion of crude oil feeds with several processing units in an integrated manner into petrochemicals. The designs utilize minimum capital expenditures to prepare suitable feedstocks for the steam cracker complex. The integrated process for converting crude oil to petrochemical products including olefins and aromatics, and fuel products, includes mixed feed steam cracking and gas oil steam cracking. Feeds to the mixed feed steam cracker include one or more naphtha fractions from hydroprocessing zones within the battery limits, including vacuum residue hydrocracking, within the battery limits, recycle streams from the C3 and C4 olefins recovery steps, and raffinate from a pyrolysis gasoline aromatics extraction zone within the battery limits. Feeds to the gas oil steam cracker include gas oil range intermediates from the vacuum gas oil hydroprocessing zone and the vacuum residue hydrocracking zone.
