Patent number: 12049595Abstract: Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.Type: GrantFiled: November 3, 2021Date of Patent: July 30, 2024Assignee: Mawetal LLCInventors: Mohammed Wohaibi, Tom F.

Publication number: 20140262944Abstract: Methods are provided for producing lubricant base oils from petrolatum. After solvent dewaxing of a brightstock raffinate to form a brightstock base oil, petrolatum is generated as a side product. The petrolatum can be hydroprocessed to form base oils in high yield. The base oils formed from hydroprocessing of petrolatum have an unexpected pour point relationship. For a typical lubricant oil feedstock, the pour point of the base oils generated from the feedstock increases with the viscosity of the base oil. By contrast, lubricant base oils formed from hydroprocessing of petrolatum have a relatively flat pour point relationship, and some of the higher viscosity base oils unexpectedly have lower pour points than lower viscosity base oils generated from the same petrolatum feed. The base oils from petrolatum are also unusual in yielding both high viscosity and high viscosity index and can be generated while maintaining a high yield.Type: ApplicationFiled: March 4, 2014Publication date: September 18, 2014Applicant: ExxonMobil Research and Engineering CompanyInventors: Jeenok T.

In the separation zones which operates at a temperature within 20° F. and a pressure within 10 psi of the pressure in the contacting zones, upgraded products are removed overhead and optionally, further treated in an in-line hydrotreater. At least a portion of the non-volatile fractions recovered from at least one of the separation zones is sent to the interstage solvent deasphalting unit, for separating unconverted heavy oil feedstock into deasphalted oil and asphaltenes. The deasphalted oil stream is sent to one of the contacting zones for further upgrade.Type: GrantFiled: September 18, 2008Date of Patent: February 12, 2013Assignee: Chevron U.S.A. Inc.Inventors: Goutam Biswas, Darush Farshid

Patent number: 8357291Abstract: The invention relates to an improved bitumen recovery process. The process includes adding water to a bitumen-froth/solvent system containing asphaltenes and mineral solids. The addition of water in droplets increases the settling rate of asphaltenes and mineral solids to more effectively treat the bitumen for pipeline transport, further enhancement, refining, or any other application of reduced-solids bitumen.Type: GrantFiled: December 19, 2008Date of Patent: January 22, 2013Assignee: ExxonMobil Upstream Research CompanyInventors: Ken N. Sury, Joseph L. Feimer, Clay R. Sutton

Publication number: 20130015100Abstract: This invention relates to systems and methods for catalytic steam cracking of non-asphaltene containing heavy hydrocarbon fractions. The method enables upgrading heavy hydrocarbons to hydrocarbons capable of being transported through pipelines and/or a pretreated step before further treatment in an upgrading refinery, including the steps of separating the heavy hydrocarbon mixture into a light fraction, a full gasoil fraction and a vacuum residue fraction with or without at least partial reduction or asphaltenes; adding a catalyst to the full gasoil and/or to the blend of this with a reduced asphaltenes fraction and subjecting the catalyst-full gasoil and/or deasphalted oil fraction to catalytic steam cracking to form an effluent stream; separating the effluent stream into a gas stream and a liquid stream; and mixing the liquid stream with the light fraction and the vacuum residue fraction to form an upgraded oil. The system includes hardware capable of performing the method.Type: ApplicationFiled: June 28, 2012Publication date: January 17, 2013Applicant: Nexen Inc.Inventors: Pedro Pereira Almao, Gustavo Luis Trujillo, Enzo Peluso, Carmen Galarraga, Clementina Sosa, Carlos Scott Algara, Francisco Lopez-Linares, Lante Antonio Carbognani Ortega, Nestor Gregorio Zerpa Reques

Patent number: 8052864Abstract: A process to prepare a sweet crude from an ash containing and heavy fraction of a tar sand oil comprising supplying an atmospheric distillation bottoms of a tar sands originated feed to a vacuum distillation to obtain a vacuum gas oil and a vacuum bottoms and contacting the vacuum gas oil with hydrogen to obtain a sweet synthetic crude. The vacuum bottoms obtained are separated into an asphalt fraction comprising between 0.1 and 4 wt % ash and a de-asphalted oil and the asphalt fraction is fed to a burner of a gasification reactor to obtain a mixture of hydrogen and carbon monoxide on which a water gas shift reaction is performed. Hydrogen sulphide and carbon dioxide are separated from the shifted gas in an acid removal unit thereby obtaining crude hydrogen which is purified and used to obtain the sweet synthetic crude.Type: GrantFiled: November 29, 2007Date of Patent: November 8, 2011Assignee: Shell Oil CompanyInventors: Jacobus Eilers, Johannes Cornelis De Jong, Franciscus Johanna Arnoldus Martens
