The use of the composition is described as being the main scavenger agent for a 1,3-dioxolane alkyl, alkenyl and/or hydroxyl derivative and ketone-based accelerator additives that include ?-diketones and cyclic ketones, saturated and/or ?-unsaturated.Type: ApplicationFiled: November 10, 2016Publication date: December 6, 2018Inventors: Camilo Enrique La Rotta HERNÁNDEZ, Luis Henrique DE FREITAS, Guilherme Bazzeggio DA FONSECA

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.

Publication number: 20180346827Abstract: Methods for operating a system having two downflow high-severity FCC units for producing products from a hydrocarbon feed includes introducing the hydrocarbon feed to a feed separator and separating it into a lesser boiling point fraction and a greater boiling point fraction. The greater boiling point fraction is passed to the first FCC unit and cracked in the presence of a first catalyst at 500° C. to 700° C. to produce a first cracking reaction product and a spent first catalyst. The lesser boiling point fraction is passed to the second FCC unit and cracked in the presence of a second catalyst at 500° C. to 700° C. to produce a second cracking reaction product and a spent second catalyst. At least a portion of the spent first catalyst or the spent second catalyst is passed back to the first FCC unit, the second FCC unit or both.Type: ApplicationFiled: April 4, 2018Publication date: December 6, 2018Applicant: Saudi Arabian Oil CompanyInventors: Sameer A.

Publication number: 20180346828Abstract: A heavy oil hydrotreating system has a prehydrotreating reaction zone, a transition reaction zone, and a hydrotreating reaction zone that are connected in series successively, sensor units, and a control unit. In the initial reaction stage, the prehydrotreating reaction zone includes at least two prehydrotreating reactors connected in parallel, and the transition reaction zone includes or doesn't include prehydrotreating reactors; in the reaction process, the control unit controls material feeding to and material discharging from each prehydrotreating reactor in the prehydrotreating reaction zone according to pressure drop signals of the sensor units, so that when the pressure drop in any of the prehydrotreating reactors in the prehydrotreating reaction zone reaches a predetermined value, the prehydrotreating reactor in which the pressure drop reaches the predetermined value is switched from the prehydrotreating reaction zone to the transition reaction zone.Type: ApplicationFiled: November 1, 2016Publication date: December 6, 2018Applicants: China Petroleum & Chemical Corporation, Fushun Research Institute of Petroleum and Petrochemicals, Sinopec Corp.Inventors: Tiebin LIU, Xinguo GENG, Yanbo WENG, Hongguang LI

Publication number: 20180346829Abstract: The subject process enhances catalytic activity for demetallization and desulfurization of a residue feed stream by injecting water into the feed and hydrotreating in two stages with interstage separation. Water injection improves the demetallation activity of the HDM catalyst and separating vapor comprising hydrogen sulfide from the demetallized effluent improves the activity of the HDS catalyst. We have discovered that the water injection and hydrogen sulfide removal together provide a profound synergetic effect.Type: ApplicationFiled: June 2, 2017Publication date: December 6, 2018Inventors: Ping Sun, Grant H.

Publication number: 20180346830Abstract: Implementations described herein generally relate to methods for purifying alpha-olefins. The alpha-olefins may be used to form drag reducing agents for improving flow of hydrocarbons through conduits, particularly pipelines. In one implementation, a method of increasing alpha-olefin content is provided. The method includes providing an olefin feedstock composition having an alpha-mono-olefin and at least one of a diolefin having an equal number of carbon atoms to the alpha-mono-olefin and/or a triolefin having an equal number of carbon atoms to the alpha-mono-olefin. The method further includes contacting the olefin feedstock composition with ethylene in the presence of a catalyst composition including an olefin metathesis catalyst. The method further includes reacting the olefin feedstock composition and ethylene at metathesis reaction conditions to produce an alpha-olefin product comprising the alpha-mono-olefin and alpha-olefins having fewer carbon atoms than the alpha-mono-olefin.Type: ApplicationFiled: May 16, 2018Publication date: December 6, 2018Inventor: Stuart N.
