Patent number: 10822547Abstract: Treatment of crude oil with basic ionic liquids (ILs), results in scavenging of any hydrochloric acid (HCl) that is present to remove the HCl. 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 HCl from distilling to the crude tower overhead.Type: GrantFiled: December 12, 2017Date of Patent: November 3, 2020Assignee: Baker Hughes Holdings LLCInventor: Jerry J.

Publication number: 20200339890Abstract: 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 16, 2020Publication date: October 29, 2020Applicant: Baker Hughes, a GE company, LLCInventors: Mary Jane Legaspi Felipe, Jerry J.
