Patent number: 10513662Abstract: Certain functionalized aldehydes scavengers may be used to at least partially scavenge sulfur-containing contaminants from fluid systems containing hydrocarbons and/or water. The contaminants scavenged or otherwise removed include, but are not necessarily limited to, H2S, mercaptans, and/or sulfides. Suitable scavengers include, but are not necessarily limited to, reaction products of glycolaldehyde with aldehydes; reaction products of glycolaldehyde with a nitrogen-containing reactant (e.g. an amine, a triazine, an imine, an aminal, and/or polyamines); non-nitrogen-containing reaction products of a hydrated aldehyde with certain second aldehydes; reaction products of 1,3,5-trioxane with hydroxyl-rich compounds (e.g. glyoxal, polyethylene glycol, polypropylene glycol, pentaerythritol, and/or sugars); and reaction products of certain aldehydes with certain phenols; and combinations of these reaction products.Type: GrantFiled: January 29, 2018Date of Patent: December 24, 2019Assignee: Baker Hughes, a GE company, LLCInventors: Jerry J.

Patent number: 10414989Abstract: Treatment of hydrocarbon streams, and in one non-limiting embodiment refinery distillates, with high pH aqueous reducing agents, such as borohydride, results in reduction of the sulfur compounds such as disulfides, mercaptans and thioethers that are present to give easily removed sulfides. The treatment converts the original sulfur compounds into hydrogen sulfide or low molecular weight mercaptans that can be extracted from the distillate with caustic solutions, hydrogen sulfide or mercaptan scavengers, solid absorbents such as clay or activated carbon or liquid absorbents such as amine-aldehyde condensates and/or aqueous aldehydes.Type: GrantFiled: March 27, 2017Date of Patent: September 17, 2019Assignee: Baker Hughes, a GE company, LLCInventors: Jerry J. Weers, Timothy J. O'Brien, Waynn C. Morgan

Publication number: 20190177622Abstract: Treatment of crude oil with basic ionic liquids (ILs), results in scavenging of any hydrochloric acid (HCI) that is present to remove the HCI. The IL is a quaternary ammonium compound having the formula R4N+X? or R3N+R?N+R3, where R is independently an alkyl group, an alkylbenzyl group, a hydroxyalkyl group, or a hydroxyalkylbenzyl group, and R is straight or branched and has 1-22 carbon atoms, R? is a straight or branched alkylene or oxyalkylene having 1 to 10 carbon atoms, and where X? is selected from the group consisting of hydroxide, carbonate, alkylcarbonate, bicarbonate or alkoxide, where the alkyl group of the alkyl-carbonate or alkoxide, if present, is straight or branched and has 1 to 8 carbon atoms. The ILs are introduced into the crude oil after the refinery desalters and before the crude distillation tower to prevent or inhibit HCI from distilling to the crude tower overhead.Type: ApplicationFiled: December 12, 2017Publication date: June 13, 2019Applicant: Baker Hughes, a GE company, LLCInventor: Jerry J.

Publication number: 20190144761Abstract: Treatment of streams containing hydrogen and/or hydrocarbons, and in one non-limiting embodiment refinery distillates, with alkyl carbonates, such as dimethylcarbonate, alone or together with at least one solvent results in reduction or removal of hydrogen sulfide (H2S) that is present to give easily removed alkyl sulfides and/or mercaptans. In one non-limiting embodiment, the treatment converts the original hydrogen sulfide into alkyl sulfides and/or mercaptans that can be extracted from the stream with caustic solutions, mercaptan scavengers, solid absorbents such as clay or activated carbon or liquid absorbents such as amine-aldehyde condensates and/or aqueous aldehydes.Type: ApplicationFiled: November 16, 2017Publication date: May 16, 2019Applicant: Baker Hughes, a GE company, LLCInventor: Jerry J.

Publication number: 20180346826Abstract: It has been discovered that contaminants such as metals and/or amines can be transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains water-soluble C5-C12 polyhydroxy carboxylic acids, ammonium salts thereof, alkali metal salts thereof, and mixtures of all of these. The composition may also optionally include a mineral acid to reduce the pH of the desalter wash water. The method permits transfer of metals and/or amines into the aqueous phase with little or no hydrocarbon phase under-carry into the aqueous phase. Resolving the emulsion into the hydrocarbon phase and the aqueous phase occurs in a refinery desalting process using electrostatic coalescence. The composition is particularly useful in treating crude oil emulsions, and in removing calcium and other metals therefrom. The polyhydroxy carboxylic acid additionally inhibits metal corrosion of metal pipe or other equipment used in a crude unit.Type: ApplicationFiled: June 4, 2018Publication date: December 6, 2018Applicant: Baker Hughes, a GE company, LLCInventors: Mary Jane Legaspi Felipe, Jerry J.

The IL is a quaternary ammonium compound having the formula R4N+ X? or X? R3N+R?N+R3 X?, where R is independently an alkyl group, an alkylbenzyl group, a hydroxyalkyl group, or a hydroxyalkylbenzyl group, and R is straight or branched and has 1-22 carbon atoms, R? is a straight or branched alkylene or oxyalkylene having 1 to 10 carbon atoms, and where X? can be hydroxide, carbonate, alkylcarbonate, bicarbonate or alkoxide, where the alkyl group of the alkylcarbonate or alkoxide, if present, is straight or branched and has 1 to 8 carbon atoms.
