The invention also relates to a device for implementing the cracking method.Type: GrantFiled: December 13, 2010Date of Patent: July 1, 2014Assignee: Total Raffinage MarketingInventors: Marc Bories, Patrick Leroy, Michael Echard, Thierry Gauthier

Patent number: 8747653Abstract: A process is disclosed for hydroprocessing two hydrocarbon streams at two different pressures. A hydrogen stream is compressed and split. A first split compressed stream is further compressed to feed a first hydroprocessing unit that requires higher pressure for operation. A second split compressed stream is fed to a second hydroprocessing unit that requires lower pressure. Recycle hydrogen from the second hydroprocessing unit is recycled back to the compression section.Type: GrantFiled: March 31, 2011Date of Patent: June 10, 2014Assignee: UOP LLCInventor: Andrew P. Wieber

Patent number: 8734636Abstract: Provided is a method of manufacturing diesel fuel, including: fractionating in a first fractionator a synthetic oil obtained by Fisher-Tropsch synthesis into at least two fractions of a middle fraction, and a wax fraction containing a wax component heavier than the middle fraction; hydroisomerizing the middle fraction by bringing the middle fraction into contact with a hydroisomerizing catalyst to produce a hydroisomerized middle fraction; hydrocracking the wax fraction by bringing the wax fraction into contact with a hydrocracking catalyst to produce a wax decomposition compound; fractionating in a second fractionator a mixture of the hydroisomerized middle fraction and the hydrocracked wax fraction into at least two fractions including a kerosene fraction and a gas oil fraction; and mixing the at least two fractions at a predetermined blend ratio to produce a diesel fuel having a kinematic viscosity at 30° C. of 2.5 mm2/s or more and a pour point of ?7.5° C. or less.Type: GrantFiled: September 25, 2008Date of Patent: May 27, 2014Assignees: Japan Oil, Gas and Metals National Corporation, Inpex Corporation, Nippon Oil Corporation, Japan Petroleum Exploration Co., Ltd., Cosmo Oil Co., Ltd., Nippon Steel Engineering Co., Ltd.Inventor: Yuichi Tanaka

Patent number: 8696885Abstract: A process is disclosed for hydrocracking hydrocarbon feed in a hydrocracking unit and hydrotreating a diesel product from the hydrocracking unit in a hydrotreating unit. The hydrocracking unit and the hydrotreating unit shares the same recycle gas compressor. A warm separator separates recycle gas and hydrocarbons from diesel in the hydrotreating effluent, so fraction of the diesel is relatively simple. The warm separator also keeps the diesel product separate from the more sulfurous diesel in the hydrocracking effluent, and still retains heat needed for fractionation of lighter components from the low sulfur diesel product.Type: GrantFiled: March 31, 2011Date of Patent: April 15, 2014Assignee: UOP LLCInventors: Andrew P. Wieber, Paul R. Zimmerman

Patent number: 8691078Abstract: An apparatus and process is disclosed for hydroprocessing hydrocarbon feed in a hydroprocessing unit and hydrotreating a second hydrocarbon. A warm separator sends vaporous hydrotreating effluent to be flashed with liquid hydroprocessing effluent to produce a vapor flash overhead that can be recycled to the hydrotreating unit to provide hydrogen requirements.Type: GrantFiled: June 24, 2011Date of Patent: April 8, 2014Assignee: UOP LLCInventors: Andrew P.

Patent number: 8663456Abstract: A hydrocarbon feed is passed to a first zone of a vaporization unit to separate a first vapor stream and a first liquid stream. The first liquid stream is passed to a second zone of the vaporization unit and contacted intimately with a counter-current steam produce a second vapor stream and a second liquid stream. The first vapor stream and the second vapor stream are cracked in the radiant section of the steam cracker to produce a cracked effluent. The second liquid stream is thermally cracked in a coking drum to produce a coker effluent and coke. The coker effluent is separated into a coker gas and a coker liquid. The coker liquid is reacted with hydrogen in the presence of a catalyst to produce a hydroprocessed product. The hydroprocessed product is separated into a gas product and a liquid product. The liquid product is fed to the vaporization unit.Type: GrantFiled: November 23, 2010Date of Patent: March 4, 2014Assignee: Equistar Chemicals, LPInventors: Robert S. Bridges, Sellamuthu G.
