Patent number: 7025874Abstract: A bitumen/steam pre-mixer and atomizing nozzle combine to produce a jet of minute liquid droplets (bitumen) in carrier gas (steam). The jet is injected into a draft tube mixer positioned in a fluid bed of hot coke particles suspended in steam and contained within a fluid coking reactor. The movement of the jet through the draft tube passageway induces a stream of coke particles in steam to be drawn into the passageway, where the jet and stream mix vigorously and bitumen droplets have an enhanced probability of contacting coke particles.Type: GrantFiled: October 4, 2002Date of Patent: April 11, 2006Assignees: Ace oil Sands, L.P., Canadian Oil Sands Commerical Trust, Canadian Oil Sands Limited, ConocoPhillips Oilsands Partnership II, Imperial Oil Resources, Mocal Energy Limited, Murphy Oil Company Ltd.,, Nexen Inc.,, Petro-Canada Oil and GasInventors: Edward W.

Patent number: 6979360Abstract: In a cyclone separator used for separating solids from gases, we discovered placing at least one opening in a lateral surface of a gas outlet conduit on a side facing away from an inlet to the cyclone separator prevents coke deposits from forming thereon. A plurality of openings may be placed on the side of the lateral surface of the gas outlet conduit facing away from the inlet. In an embodiment, no openings are placed on a side of the lateral surface facing the inlet to the cyclone separator.Type: GrantFiled: May 13, 2003Date of Patent: December 27, 2005Assignee: UOP LLCInventors: Ismail B.

Patent number: 6846405Abstract: This invention is to a circulating fluid bed reactor that is designed so as to have the ability to adjust catalyst holdup within the reaction zone of the reactor while maintaining substantially constant catalyst circulation rate through the reaction zone. The ability to adjust catalyst hold up independently of catalyst circulation rate provides an advantage of having the ability to maintain a constant conversion level as catalyst activity or feed rates change.Type: GrantFiled: August 31, 2001Date of Patent: January 25, 2005Assignee: ExxonMobil Chemical Patents Inc.Inventors: James R. Lattner, Jeffrey S. Smith, Rathna P. Davuluri

Patent number: 6814857Abstract: A process for contacting a bed of particulate material, usually catalyst, with a transverse flow of fluid is disclosed. The particulate material moves or is prevented from not moving, while the fluid passes through the bed at a rate greater than the stagnant bed pinning flow rate. This invention is applicable to hydrocarbon conversion processes and allows for higher fluid throughput rates compared to prior art processes.Type: GrantFiled: January 31, 2002Date of Patent: November 9, 2004Assignee: UOP LLCInventors: Weikai Gu, Paul A. Sechrist

Patent number: 6780308Abstract: A baffle-style stripper for an FCC process comprising sloped baffles in which a greater volumetric flow rate of stripping medium permeates openings in a bottom section of the baffle than through a top section of the baffle for low catalyst flux stripping operations. When low catalyst flux is used, the catalyst runs from baffle to baffle closer to the bottom edge of the baffle. Hence, more fluidization from stripping medium is concentrated near the lower edge of the baffle. The greater fluidization at the bottom section of the baffle is accomplished by providing greater opening area per baffle area in the lower section of the baffle than in the top section of the baffle.Type: GrantFiled: November 21, 2001Date of Patent: August 24, 2004Assignee: UOP LLCInventors: Brian W. Hedrick, Thuy Khanh T. Nguyen

Patent number: 6755962Abstract: A slurry phase reactor is designed to treat extra heavy petroleum crude in a combination of thermal-zone and catalytic-zone in a counterflow system where liquid feed is added to the top and hydrogen at the bottom. Feed enters the gas-phase thermal zone, where it passes to a liquid-phase thermal zone. In the liquid-phase thermal zone, the hydrocarbon is thermally cracked and the unreacted liquid is further passed to a catalytic-zone below in communication with the thermal-zone. Catalyst can be added or removed as required in a continuous mode without shutting down the system. The heat generated inside the catalytic cracking zone is distributed to the entire reactor as the gaseous product flows upward. Feed is brought to the reaction conditions by the heat recovered from the gas-phase zone. Reaction temperature could be controlled by feed temperature.Type: GrantFiled: May 9, 2001Date of Patent: June 29, 2004Assignee: ConocoPhillips CompanyInventor: Dwijen K. Banerjee

Publication number: 20040104149Abstract: Disclosed is an apparatus and process for controlling reactor volume in a fluidized catalytic conversion reactor. Changing volume results in controllable residence time and/or space velocity. Reactor volume may be changed by altering the feed distributor elevation, diluent flow rate or the number of reaction subsections to which feed is distributed.Type: ApplicationFiled: December 20, 2002Publication date: June 3, 2004Inventors: David A. Lomas, Lawrence W. Miller

Publication number: 20040104148Abstract: Disclosed is an apparatus and process for controlling space velocity in a fluidized catalytic conversion reactor. The catalyst flux rate can be adjusted during the process of the reaction to adjust the space velocity and maintain a fast fluidized flow regime therein. The set parameter in the reactor may be pressure drop which is proportional to catalyst density.Type: ApplicationFiled: December 20, 2002Publication date: June 3, 2004Inventors: David A.

Patent number: 6743280Abstract: The present invention relates to a method for separating entrained particles from a gas in a fluidised bed reactor system and fluidised bed reactor system including a particle separator for separating entrained particles from a gas. The particles are separated from the gas flowing in a direction other than the main gas flow direction, whereby the separation is multidimensional. The gas is allowed to pass from the outside of the configuration to the inside thereof and/or vice versa, wherein the particles are separated from the gas during such a travel. The gas flow can be multileveled.Type: GrantFiled: February 25, 2002Date of Patent: June 1, 2004Assignee: TPS Termiska Processer ABInventors: Lennart Ahlgren, Erik Rensfelt
