Patent number: 5120428Abstract: A process is described for removing mineral or ash constituents from heavy hydrocarbon residues, such as those resulting from coal-oil coprocessing, residue hydrocracking or coal liquifaction. The process comprises the steps of: (a) intimately mixing the ash-containing heavy hydrocarbon oil residue with a surfactant and a pH-conditioned aqueous solution under high shear mixing conditions to disperse the ash-containing residue in the aqueous phase thereby creating a fine oil-in-water emulsion, (b) adding a strong oxidizing agent to the emulsion to thereby break the emulsion and release the ash into the aqueous phase and (c) separating the ash-containing aqueous phase from the oil phase. The HLB method for characterizing the emulsion forming activity of a surface active material is described in M. J. Rosen, Surfactants and Interfacial Phenomena, John Wiley & Sons, New York (1989), incorporated herein by reference.Type: GrantFiled: June 6, 1991Date of Patent: June 9, 1992Assignee: Energy Mines & Resources CanadaInventors: Michio Ikura, Norman E. Cooke, Marc Halevy, Martin E. Weber

Patent number: 4975176Abstract: The process permits to produce bitumens having a high penetration value by oxidation of base bitumens with small volumes of gaseous oxidizers, preferably air, at a temperature between 170.degree. and 250.degree., preferably 200.degree. C., by turbodispersion of the gaseous phase in the bituminous mass by means of a rapid turbodisperser.By adding appropriate fluxes and operating in the presence of catalysts, the technological characteristics of the end product can be varied until obtaining blends of bitumens that are adapted for new applications.The turbodisperser is provided with an impeller constituted by a plane disk carrying on its periphery a series of teeth made preferably with the active side located on the diameter of the impeller and the angle at the vertex greater than 45.degree..Type: GrantFiled: July 1, 1987Date of Patent: December 4, 1990Inventors: Fernando Begliardi, Alessandro Cori

Patent number: 4839022Abstract: Heavy hydrocarbon containing sludges such as refinery waste streams, oil storage tank sludges and marine oil tanker ballast are treated by passing the sludges in a flow stream through an indirect dryer to vaporize liquids having a boiling point at atmospheric pressure of less than about 700.degree. F. and to provide substantially dried solid particles discharged from the dryer. The dried particles, containing heavy hydrocarbons as a coating or as a part of the solids, are conducted to a combustor/oxidizer and exposed to a high velocity flow stream of oxygen containing gas, typically low pressure forced air, to burn the residual hydrocarbons in the solids and to reduce heavy metals and the like to oxides thereof. A sludge handling system includes a rotary disk type indirect dryer connected to a lift pipe type combustor/oxidizer for thorough exposure of the dried solids to an oxygen containing atmosphere.Type: GrantFiled: November 8, 1985Date of Patent: June 13, 1989Assignee: Atlantic Richfield CompanyInventor: James L. Skinner

Patent number: 4818371Abstract: A method is disclosed for reducing the viscosity of a hydrocarbon feed. The feed is heated from an initial temperature to a second temperature and an oxidizing agent is introduced to oxidize components in the feed and provide heat to increase the temperature of the feed to a reaction temperature. The reaction temperature is maintained to produce a reaction product having a lower viscosity than the feed.Type: GrantFiled: June 5, 1987Date of Patent: April 4, 1989Assignee: Resource Technology AssociatesInventors: Richard L. Bain, John R. Larson

Patent number: 4631384Abstract: Process for the combustion of bitumen, wherein the bitumen is softened by preheating and is then introduced into a combustion chamber, traversed by oxygen in excess subject to ionization by an intense ultra-high frequency field, so as to raise the surface of the bitumen to a temperature above 1000.degree. C., thereby ensuring its vaporization and rapid combustion in the thus produced oxygen plasma.Type: GrantFiled: February 13, 1984Date of Patent: December 23, 1986Assignee: Commissariat a l'Energie AtomiqueInventor: Ayme Cornu
