Publication number: 20120043256Abstract: Solid organic acids may be introduced into hydrocarbon solvents to form dispersions; the dispersions in turn may be introduced into crude oil. A wash water may be added to the crude oil to create an emulsion. The organic acids may transfer metals and/or amines from a hydrocarbon phase into an aqueous phase in an electrostatic desalter which resolves the emulsion into the two phases. Suitable solid organic acids include, but are not necessarily limited to, C2-C4 alpha hydroxyacids, such as, but not necessarily limited to, glycolic acid, malic acid, maleic acid, malonic acid, succinic acid and even sulfamic acid, chloroacetic acid, thiomalic acid, including esters of, polymers of, amine salts of, alkali metal salts of, and/or ammonium salts of all of these acids.Type: ApplicationFiled: September 9, 2011Publication date: February 23, 2012Applicant: Baker Hughes IncorporatedInventors: Lawrence N. Kremer, Jerry J. Weers, Corina L. Sandu

Publication number: 20120031810Abstract: Corrosive amine salts in hydrocarbon streams such as desalted crude oil streams can be prevented or avoided by adding certain amine scavenging chemicals to the streams to remove the amines therefrom. Suitable amine scavengers include, but are not necessarily limited to, carboxylic anhydrides and copolymers of carboxylic anhydrides, aromatic anhydrides, isocyanates, polyisocyanates, and epoxides. The non-corrosive reaction products of the amines and/or ammonia with these scavengers are preferably oil-soluble, non-basic and thermally stable. The amine scavengers bind up and react with the amines and/or ammonia to keep them from reacting with materials such as acids (e.g. HCl) to form corrosive amine salts.Type: ApplicationFiled: October 19, 2011Publication date: February 9, 2012Applicant: Baker Hughes IncorporatedInventors: Joseph L. Stark, George G. Duggan, Walter A. Boyd, Jerry J. Weers

Publication number: 20110172473Abstract: It has been discovered that metals can be removed or transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains a demulsifier (for instance, an oxyalkylated alkyl resin and/or a crosslinked polypropylene glycol), a surfactant, a diketone and a solvent (for instance an aromatic solvent). The method may also include introducing a hydroxyl carboxylic acid and/or at least one mineral acid to reduce the pH of the desalter wash water. The method permits transfer of metals into the aqueous phase with little or no hydrocarbon phase undercarry into the aqueous phase. The composition is particularly useful in treating crude oil emulsions, and in removing iron therefrom.Type: ApplicationFiled: January 18, 2011Publication date: July 14, 2011Applicant: Baker Hughes IncorporatedInventors: Tran M.

Publication number: 20110113680Abstract: Hydrogen sulfide and mercaptans in hydrocarbons, gas mixtures of hydrocarbons and the like may be scavenged therefrom by being brought into intimate contact with a mercaptan scavenger formulation of quaternary ammonium alkoxide or hydroxide in the presence of a high oxidative state metal such as cobalt, iron, chromium and/or nickel. The high oxidative state metal, being an oxidizer, acts as a catalyst when combined with the quaternary ethoxide or hydroxide for improved mercaptan scavenging performance.Type: ApplicationFiled: November 22, 2010Publication date: May 19, 2011Applicant: Baker Hughes IncorporatedInventors: Timothy J.

Patent number: 7918905Abstract: The addition of strong neutralizing amines to react with free fatty acid in biodiesel fuels that may be left from some synthesis routes can lower the total acid number (TAN) of the biodiesel fuel. Surprisingly, the strong neutralizing amines do not interfere with the biodiesel fuel itself which may be primarily fatty acid methyl esters. These strong neutralizing amines may also improve the oxidative stability of biodiesel fuels.Type: GrantFiled: May 17, 2007Date of Patent: April 5, 2011Assignee: Baker Hughes IncorporatedInventors: Lawrence N. Kremer, Jerry J. Weers, Jennifer D. Draper
