Publication number: 20080001125Abstract: Corrosion induced by the presence of naphthenic acids in hydrocarbon fluids, particularly where such fluids are at elevated temperatures, may be inhibited or controlled through use of corrosion inhibiting compositions comprising a combination of a minor portion of a phosphorus-based constituent and a major portion of a sulfur-based constituent, nitrogen-based constituent, or combination thereof. In another embodiment the sulfur-based constituent and/or nitrogen-based constituent may be used without any phosphorus-based constituent. Where the compounds are appropriately selected, the compositions may inhibit corrosion to a degree comparable or nearly comparable to the inhibition provided by an equal amount of some conventional phosphorus-based compounds alone, but are significantly less likely to impair catalyst activity in downstream cracking and refinery operations.Type: ApplicationFiled: November 17, 2006Publication date: January 3, 2008Applicant: Baker Hughes IncorporatedInventors: Michael J.

Patent number: 7141174Abstract: The present invention provides a method of treating boiler and condensate water by the addition of an effective amount of a hydroxyamine-acid ester treatment reagent or an all-in-one treatment composition comprising a hydroxyamine-acid ester. Modification of a hydroxyamine to a hydroxyamine-acid ester generally reduces the odors of the amine while providing a means to formulate the composition into a solid form. The ester typically decomposes at conditions in the boiler to release the hydroxyamine to treat the boiler water. Other components used to treat boiler water and condensate related problems may be formulated with the hydroxyamine-acid ester to form the all-in-one treatment composition.Type: GrantFiled: September 22, 2004Date of Patent: November 28, 2006Assignee: JohnsonDiversey, Inc.Inventors: Lyle H. Steimel, James Emerson, Sue Ann Balow

Patent number: 6800594Abstract: An environmentally friendly corrosion inhibiting formulation for the oil-water interface of pipe lines and oil well drilling systems which is prepared pursuant to a process including the steps of reacting an acid selected from the group consisting of a fatty acid anhydride and a 21 carbon dibasic acid with an amine or imidazoline to form a corrosion inhibitor consisting essentially of a fatty acid derivative; dissolving the inhibitor in a fatty acid oil or ester selected from the group consisting of soybean oil or methyl soya ester; adding water dispersing agents consisting of sulfonates and a long chain ethoxylated alcohol; and adjusting the viscosity with an alcohol comprising isopropanol.Type: GrantFiled: January 24, 2003Date of Patent: October 5, 2004Assignee: Cortec CorporationInventors: Boris A. Miksic, Alla Furman, Margarita Kharshan
