Patent number: 10392712Abstract: Pitting corrosion of stainless steel occurs in solutions of organic acid, such as tartaric acid, in an electrolyte solution with methanol. However, methanolic solutions containing at least one organic halide and at least one organic hydroxyl-acid and some water provide reduced pitting corrosion of stainless steel. The organic hydroxyacid may be a hydroxy acid containing 2 to 10 carbon atoms with at least one hydroxyl group and at least one carboxylic acid group, in a non-limiting example, glycolic acid. The pH of the methanolic solution may range from about 3.5 to about 8.Type: GrantFiled: July 8, 2017Date of Patent: August 27, 2019Assignee: Baker Hughes, a GE company, LLCInventors: Zhengwei Liu, Sunder Ramachandran, Vaithilingam Panchalingam, Timothy Z.

Patent number: 8575358Abstract: 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: GrantFiled: March 2, 2012Date of Patent: November 5, 2013Assignee: Baker Hughes IncorporatedInventors: Gordon T.

Patent number: 8425628Abstract: 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: GrantFiled: August 29, 2012Date of Patent: April 23, 2013Assignee: Baker Hughes IncorporatedInventors: Viet Q.
