Naphtha and ultra low sulfur diesel are recovered in a common fractionation column.Type: GrantFiled: February 2, 2005Date of Patent: June 16, 2009Assignee: UOP LLCInventors: Vasant P. Thakkar, Richard K. Hoehn

Patent number: 7531082Abstract: In the refining of crude oil, hydroprocessing units such as hydrotreaters and hydrocrackers are used to remove impurities such as sulfur, nitrogen, and metals from the crude oil. They are also used to convert the feed into valuable products such as naphtha, jet fuel, kerosene and diesel. The current invention provides very high to total conversion of heavy oils to products in a single high-pressure loop, using multiple reaction stages. A hot high pressure separator is located between the first and second reaction stages. Overhead from the separator is treated in a distillate upgrader, which may operate in co-current or countercurrent mode.Type: GrantFiled: March 3, 2005Date of Patent: May 12, 2009Assignee: Chevron U.S.A. Inc.Inventors: Ujjal K. Mukherjee, Art Dahlberg

Patent number: 7507325Abstract: The invention relates to a process and installation for treating heavy petroleum feedstocks for producing a gas oil fraction that has a sulfur content of less than 50 ppm and most often 10 ppm that includes the following stages: a) mild hydrocracking in a fixed catalyst bed, b) separation from hydrogen sulfide of a distillate fraction that includes a gas oil fraction and a heavier fraction than the gas oil, c) hydrotreatment (including desulfurization) of said distillate fraction, and d) separation of a gas oil fraction with less than 50 ppm of sulfur. Advantageously, the heavy fraction is sent into catalytic cracking. The process preferably operates with make-up hydrogen that is brought to stage c), and very advantageously all of the make-up hydrogen of the process in introduced in stage c).Type: GrantFiled: May 23, 2002Date of Patent: March 24, 2009Assignee: Institut Francais du PetroleInventors: Christophe Gueret, Pierre Marion, Cecile Plain, Jerome Bonnardot, Eric Benazzi, Olivier Martin

Patent number: RE41120Abstract: A process for removing organic sulfur compounds from heavy boiling range naphtha in a dual purpose reactor wherein the heavy boiling range naphtha is fed downflow over a fixed bed of hydrodesulfurization zone and then treated with hydrogen in a hydrodesulfurization catalytic distillation zone. Vapor containing hydrogen sulfide is removed between the zones. Preferably the heavy boiling range naphtha is produced by treating a full boiling range naphtha to concurrently react diolefins and mercaptans and split the light and heavy boiling range naphtha in a distillation column reactor.Type: GrantFiled: January 8, 2008Date of Patent: February 16, 2010Assignee: Catalytic Distillation TechnologiesInventor: Amarjit S.
