Patent number: 5980733Abstract: A method of removing hazardous sulfur compounds, such as hydrogen sulfide, mercaptans and sulfur oxides, from a fluid stream comprising contacting the fluid stream with an aqueous composition comprised of a tertiary amine oxide. The amine oxide reacts with the hazardous sulfur compounds to eliminate the compounds from the fluid stream.Type: GrantFiled: August 13, 1998Date of Patent: November 9, 1999Assignee: United Laboratories InternationalInventors: Bevan C. Collins, Nicholas J. Savaiano, Pat A. Mestetsky

Patent number: 5964906Abstract: A process for preparing a hydrocarbon in water emulsion includes the steps of: providing a hydrocarbon phase containing a contaminant selected from the group consisting of vanadium, sulfur, and mixtures thereof; mixing a solid additive with the hydrocarbon phase, the solid additive being selected from the group consisting of calcium compounds, magnesium compounds and mixtures thereof so as to provide a hydrocarbon suspension including the solid additive; and forming an emulsion from the hydrocarbon suspension and an aqueous phase including a surfactant so as to form a combustible hydrocarbon in water emulsion having the solid additive suspended in the hydrocarbon phase.Type: GrantFiled: November 10, 1997Date of Patent: October 12, 1999Assignee: Intevep, S.A.Inventors: Ignacio A. Layrisse, Nilia C Romero, Gustavo A. Nunez
