Publication number: 20220213388Abstract: A hydrotreatment unit for an oxygenate feedstock is provided, the unit including: a hydrotreatment reactor; a first cooling unit; a high-pressure separator and a low pressure flash unit. The hydrotreatment unit is arranged to feed at least a part of the hydrogen-rich stream from the high-pressure separator to the hydrotreatment reactor; and the hydrotreatment unit is arranged to feed a part of the degassed hydrocarbon-rich stream from said low pressure flash unit as a hydrocarbon recycle stream to the hydrotreatment reactor. Also, a method for hydrotreating an oxygenate feedstock using the hydrotreatment unit.Type: ApplicationFiled: July 2, 2020Publication date: July 7, 2022Applicant: HALDOR TOPSØE A/SInventors: Ole Frej ALKILDE, Gordon Gongngai LOW, Steven W. STUPIN

Patent number: 9580663Abstract: A hydrocracking process by the steps of: (a) providing a mixture comprising hydrocarbonaceous feedstock and hydrogen; (b) obtaining a hydrocracked effluent; (c) separating the hydrocracked effluent into a first vapor portion and a first liquid portion; (d) heating the first liquid portion to form a vapourised first liquid portion; (e) feeding the vaporised first liquid portion to a fractionation section producing individual product fractions including a heavy bottom fraction; (f) withdrawing from the fractionation section the heavy bottom fraction; (g) splitting the heavy bottom fraction in a stream for stripping and a heavy bottom fraction recycle stream; (h) stripping the stream for stripping, with a stripping medium, in a counter current stripping column to form an overhead vapor and a stripped liquid; (i) feeding the overhead vapor to the fractionation section, to a recycle stream or to a position upstream the fractionation section.Type: GrantFiled: October 5, 2011Date of Patent: February 28, 2017Assignee: Haldor Topsoe A/SInventors: Gordon Gongngai Low, Michael Glenn Hunter

Patent number: 8333884Abstract: Partial conversion hydrocracking process comprising the steps of (a) hydrotreating a hydrocarbon feedstock with a hydrogen-rich gas to produce a hydrotreated effluent stream comprising a liquid/vapor mixture and separating the liquid/vapor mixture into a liquid phase and a vapor phase, and (b) separating the liquid phase into a controlled liquid portion and an excess liquid portion, and (c) combining the vapor phase with the excess liquid portion to form a vapor plus liquid portion, and (d) separating an FCC feed-containing fraction from the controlled liquid portion and simultaneously hydrocracking the vapor plus liquid portion to produce a diesel-containing fraction, or hydrocracking the controlled liquid portion to produce a diesel-containing fraction and simultaneously separating a FCC feed-containing fraction from the vapor plus liquid portion. The invention also includes an apparatus for carrying out the partial conversion hydrocracking process.Type: GrantFiled: November 23, 2009Date of Patent: December 18, 2012Assignee: Haldor Topsoe A/SInventors: Michael Glenn Hunter, Angelica Hidalgo Vivas, Lars Skov Jensen, Gordon Gongngai Low
