Patent number: 6337011Abstract: A method for lowering the cloud/pour point of a waxy crude oil in locations where size and/or weight of the facility may need to be limited (i.e. arctic zones and offshore). The major components of the system comprise a fractionation/quench tower and a reaction furnace. The furnace has sufficient heat input to initiate thermal cracking of wax and the fractionation tower is operated at a temperature sufficient to flash off light hydrocarbons but also low enough to quench thermal cracking reaction. The feed to the furnace comprises a portion of the bottoms stream from the tower and the furnace output is fed back into the tower bottom to be quenched.Type: GrantFiled: March 15, 2000Date of Patent: January 8, 2002Assignee: Halliburton Energy Services, Inc.Inventors: Gee S. Fung, Philip E. DePalm, Puneet Sharma

Patent number: 6096192Abstract: A bitumen is rendered pipelineable by partially hydroconverting the bitumen and then adding sufficient diluent to the partially hydroconverted bitumen to provide a mixture having an API gravity at 15.degree. C. of at least 19.degree. and a viscosity at 40.degree. C. in the range of about 35 to about 60 cP.Type: GrantFiled: July 14, 1998Date of Patent: August 1, 2000Assignee: Exxon Research and Engineering Co.Inventors: Ronald Damian Myers, John Brenton MacLeod, Mainak Ghosh, Tapan Chakrabarty

Patent number: 6054496Abstract: A method for producing a heavy crude oil from a subterranean formation through a wellbore, transporting the heavy crude oil to a market location and converting the heavy crude oil into a product distillate hydrocarbon stream and by-products such as heat, steam, electricity and synthesis gas by separating distillable components of the heavy crude oil by distillation and solvent deasphalting and converting the asphaltic residual portion of the heavy crude oil in a fluidized bed to at least one of heat, steam, electricity or synthesis gas. The method also produces diluent hydrocarbons useful as a separate product, a distillable hydrocarbon stream or a diluent for use in the production and transportation of the heavy crude oil.Type: GrantFiled: September 11, 1997Date of Patent: April 25, 2000Assignee: Atlantic Richfield CompanyInventors: Steven D. Crane, Gary L. Beer, Harrison F. Blacker

Patent number: 5935423Abstract: A method for producing a heavy crude oil from a subterranean formation via a wellbore, transporting the heavy crude oil to a market and producing a distillable hydrocarbonaceous stream from the crude oil, the method includes: producing the heavy crude oil from a subterranean formation via a wellbore, mixing the heavy crude oil with a diluent to form a mixture, transporting the mixture to a selected location and converting the heavy crude oil into a product distillate hydrocarbon stream and at least one of heat, steam, electricity and synthesis gas by separating distillable components of the heavy crude oil by distillation and converting the residual portion of the heavy crude oil in a fluidized bed to at least one of heat, steam, electricity or synthesis gas. The diluent is typically a hydrocarbonaceous distillate material which may be recovered as a separate product.Type: GrantFiled: April 12, 1997Date of Patent: August 10, 1999Assignee: Atlantic Richfield CompanyInventors: Steven D. Crane, Gary L. Beer, Harrison F. Blacker

Patent number: 5846404Abstract: A selenium-containing aqueous stream may be used as a quenching water stream and optionally a cutting water stream in a delayed coking process to effectuate the removal of selenium from the selenium-containing aqueous stream resulting in the formation of a selenium-coke product. In addition, selenium may be concentrated in selenium-containing stripped sour water streams by recycling the stream in one or more hydroprocessing units and one or more sour water stripper units and subsequently removed by using a portion of the selenium-containing stripped sour water stream as a quenching water stream and optionally a cutting water stream in a delayed coking process.Type: GrantFiled: September 15, 1994Date of Patent: December 8, 1998Assignee: Shell Oil CompanyInventors: Raymond Tom Fong, John Bernard Rodden, Jack Thomas Veal, Charles Lee Meyer, Michael Norris Treybig, Coley Jerald Williams, Richard Joseph Horvath

Patent number: 5824214Abstract: Heavy crude oil containing at least 1% by weight water is hydrotreated and upgraded while being produced downhole in a production well. During production the heavy crude oil containing water is subjected to sonic energy at a low frequency of 400 Hz to 10 kHz downhole in the presence of a metal hydrogenation catalyst that causes the water in the crude oil to react and form hydrogen which then hydrotreats and upgrades the heavy crude oil during production. In another embodiment, if the heavy crude oil does not contain water, the hydrogen may be formed in-situ by contacting the heavy crude oil downhole with a chemical compound comprising ammonia, hydrazine and formic acid that in the presence of a metal hydrogenation catalyst and sonic energy causes the chemical compound to react and form hydrogen which then hydrotreats the heavy crude oil during production. Suitable catalysts include nickel on zinc dust, platinum on carbon and palladium on carbon, preferably nickel on zinc dust.Type: GrantFiled: July 11, 1995Date of Patent: October 20, 1998Assignee: Mobil Oil CorporationInventors: James M.
