Publication number: 20120230893Abstract: An apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a particulate solid material to form a heavy hydrocarbon slurry and hydrocracked in a slurry hydrocracking unit to produce vacuum gas oil (VGO) and pitch. A first vacuum column separates VGO from pitch, and a second vacuum column further separates VGO from pitch. As much as 15 wt-% of VGO can be recovered by the second vacuum column and recycled to the slurry hydrocracking unit. A pitch composition is obtained which can be made into particles and transported without stickin together.Type: ApplicationFiled: May 16, 2012Publication date: September 13, 2012Applicant: UOP LLCInventors: James F. McGehee, David N. Myers, Mark Van Wees, Paul R. Zimmerman, Ruth Buskus Kleinworth

Publication number: 20100248946Abstract: One exemplary embodiment can be a process for making a catalyst including an effective amount of iron for catalyzing one or more reactions in a hydrocarbon conversion system. The process can include grinding and coating the particles. The ground particles can have an effective amount of iron, and substantially all the particles may have a maximum dimension no larger than about 130 microns. The coating can have an effective amount of one or more hydrocarbons to provide the catalyst with improved flowability.Type: ApplicationFiled: March 27, 2009Publication date: September 30, 2010Inventors: Lorenz J.

Patent number: 7802435Abstract: A cogeneration process is provided for a regenerator in a fluidized catalytic cracking system having a reactor and a regenerator. The process includes introducing flue gas from the regenerator into a heating unit to produce heated flue gas at a temperature of at least about 900° C. The heated flue gas is introduced into an expander. Steam is heated with the heated flue gas to produce heated steam. The heated steam is introduced into a turbine to extract energy from the steam.Type: GrantFiled: December 21, 2006Date of Patent: September 28, 2010Assignees: UOP LLC, BP Corporation North America Inc.Inventor: James F.

Publication number: 20100122939Abstract: The recovery of solids, and particularly solid particulates used as catalysts in slurry hydroprocessing, from asphaltene containing hydrocarbons is improved by controlling asphaltene precipitation. The formation of agglomerates of the solid particulates, having an increased diameter, results in the presence of precipitated asphaltenes, possibly due to flocculation. Asphaltene precipitation is controlled by varying process parameters or introducing additional diluent or flush streams that change the polarity of an asphaltene containing liquid product recovered from an effluent of a slurry hydroprocessing reaction zone.Type: ApplicationFiled: November 15, 2008Publication date: May 20, 2010Inventors: Lorenz J. Bauer, Tom N. Kalnes, James F. McGehee

Publication number: 20100122934Abstract: Integrated slurry hydrocracking (SHC) and coking methods for making slurry hydrocracking (SHC) distillates are disclosed. Representative methods involve passing a slurry comprising a deasphalted oil (DAO) produced in a solvent deasphalting (SDA) process, optionally with recycled SHC gas oil and recycled SHC pitch, and a solid particulate through an SHC reaction zone in the presence of hydrogen to obtain the SHC distillate. Recovery and recycle of SHC gas oil and pitch from the SHC effluent improves the overall conversion to naphtha and distillate products and decreases catalyst requirements.Type: ApplicationFiled: November 15, 2008Publication date: May 20, 2010Inventors: Robert S.

Publication number: 20100034710Abstract: A coking process and apparatus may include cracking a hydrocarbon feed stream with a catalyst, generating a hot flue gas from regenerating said catalyst, directing the hot flue gas into a spray contactor, spraying a heavy residual oil into the spray contactor, and coking the heavy residual oil utilizing the hot flue gas as a heat source. The hydrocarbon feed stream and the heavy residual oil may each or both be generated by a solvent deasphalter. The coking process produces a solid coke product and volatile hydrocarbons which leave with the hot gas and may be burned in an oxidizer to generate steam with the pressure energy recovered by a turbo-expander.Type: ApplicationFiled: October 16, 2009Publication date: February 11, 2010Applicant: UOP LLCInventor: James F.

Patent number: 7622061Abstract: The present invention is a process and apparatus for conserving loss of heat while forming and crystallizing polymer particles in a liquid. The cooling liquid quenches the polymer during particle molding to facilitate shaping. The cooling liquid cools the polymer particles not below a temperature that allows adequate crystallization to occur. Cooling liquid is quickly switched with a warming liquid, so the temperature of the polymer is in the crystallization range and the heat of crystallization self-heats the polymer to a higher temperature.Type: GrantFiled: February 23, 2009Date of Patent: November 24, 2009Assignee: UOP LLCInventor: James F.
