Publication number: 20120172604Abstract: Oxazolidinium compounds are formed by the reaction of a halohydrin or an epoxide with a secondary amine and an aldehyde or a ketone. The oxazolidinium compounds are formed directly and do not require the reaction of a pre-formed oxazolidine with an alkylating agent. The compounds are useful as gas hydrate inhibitors in oil and gas production and transportation. The oxazolidinium compounds have the structure: where R is a saturated or unsaturated alkyl group containing from 3 to 20 carbon atoms, where R has an absence of aryl groups; R1 and R2 each independently have 1 to 20 carbon atoms, may be linear, branched or cyclic; linear, branched or cyclic groups having 1 to 20 carbon atoms substituted with alkyl groups, aryl groups, alkylaryl groups, and aryl groups substituted with alkoxy groups, and X is selected from the group consisting of chlorine, fluorine, bromine or iodine.Type: ApplicationFiled: March 2, 2012Publication date: July 5, 2012Applicant: BAKER HUGHES INCORPORATEDInventors: Gordon T.

Patent number: 8048827Abstract: Gas hydrate formation in a well completion fluid in the annular space of a hydrocarbon producing well may be controlled by the incorporation of effective amounts of one or more low dose gas hydrate inhibitors, including but not limited to, low dosage hydrate inhibitors (LDHIs), kinetic hydrate inhibitors, dendrimeric or branched compounds, linear polymers and copolymers, grafted or branched linear polymers and copolymers, and onium compounds.Type: GrantFiled: December 18, 2009Date of Patent: November 1, 2011Assignee: Baker Hughes IncorporatedInventors: Gordon T.

Publication number: 20110061292Abstract: Reacting an alkylene carbonate, such as ethylene carbonate, with dimer acid in the presence of a catalyst, such as a tertiary amine catalyst, gives a dimer acid diester having essentially no sulfur, and thus may be added to ultra-low sulfur diesel fuel downstream of a refinery. The diester enhances the lubricity properties of hydrocarbon fuels, increases their service life and fuel efficiency. The manufacturing process time may be decreased significantly compared with a process using ethylene glycol instead of ethylene carbonate, and much less ethylene glycol by-product results.Type: ApplicationFiled: September 3, 2010Publication date: March 17, 2011Applicant: Baker Hughes IncorporationInventors: Viet Q. Hoang, Philip L. Leung, Gordon T. Rivers

Patent number: 7837746Abstract: A method for inhibiting formation of hydrocarbon hydrates in mixtures of water and a hydrate-forming guest molecule involves adding a reaction product to the mixtures in an effective amount to inhibit formation of the hydrocarbon hydrates under conditions otherwise effective to form the hydrocarbon hydrates in the absence of the reaction product. The product is made by the reaction of first reactant that is an amine or polyamine, or alcohol or polyalcohol, with a second, aldehyde reactant and a third reactant that is an alcohol or polyalcohol or, an amide or polyamide. Preferably, if the first and third reactants are both an alcohol or both a polyalcohol, they are not the same. A non-limiting example of a suitable amine would be a fatty alkyl amine, while formaldehyde would be a non-limiting of a suitable aldehyde and polyacrylamide would be a suitable third reactant.Type: GrantFiled: October 6, 2006Date of Patent: November 23, 2010Assignee: Baker Hughes IncorporatedInventors: Gordon T. Rivers, Daniel L. Crosby

Publication number: 20080293597Abstract: A sterically hindered quaternary ammonium composition is prepared by contacting a solvent having hydroxyl functionality, a halohydrin, and a sterically hindered tertiary amine, under reaction conditions sufficient to produce a sterically hindered quaternary ammonium compound. The reaction proceeds with excellent yield. The resulting compounds are particularly useful for inhibiting formation of hydrates in hydrocarbon reservoirs and pipelines. Novel compositions of matter include sterically hindered quaternary ammonium compounds conforming to the formulas C27H58XNO2 and C29H63XNO2, wherein X is a halogen.Type: ApplicationFiled: August 1, 2008Publication date: November 27, 2008Applicant: BAKER HUGHES INCORPORATEDInventor: Gordon T.

Patent number: 7438877Abstract: Selective, irreversible removal of hydrogen sulfide (H2S) and other sulfhydryl compounds from a gas stream, such as sour natural gas and sour hydrocarbon liquids is achieved with a scavenging agent having hydroxyalkyl functionality and alkylamine functionality. This scavenger possesses a higher capacity for H2S removal compared with a scavenger having only hydroxyalkyl functionality. The scavenging agent is made by reacting at least one alkanolamine and at least one alkyl amine with an aldehyde, such as formaldehyde.Type: GrantFiled: September 1, 2006Date of Patent: October 21, 2008Assignee: Baker Hughes IncorporatedInventors: Tauseef Salma, Alexander A.
