Patent number: 10590348Abstract: The disclosure deals with a slurry bubble column reactor for converting a gas mixture comprising carbon monoxide and hydrogen into liquid hydrocarbons. The slurry bubble column reactor features a slurry bed of catalyst particles, an inlet conduit for feeding the gas mixture into the slurry bed, a filtration zone for separating the liquid hydrocarbons from the catalyst particles and a liquid outlet conduit for withdrawing the separated hydrocarbons from the filtration zone. The filtration zone is situated in the slurry bubble column reactor such that the slurry bed is found in a first and a second heat exchange zone with the filtration zone arranged between the first and the second heat exchange zone.Type: GrantFiled: May 19, 2017Date of Patent: March 17, 2020Assignees: L'AIR LIQUIDE Société Anonyme pour l'Etude et l'Exploitation des Procédés Georges Claude, The Petroleum Oil and Gas Corporation of South Africa (SOC) LtdInventors: Marc Brueschke, Patrick Otto Taylor, Pål Søraker

Publication number: 20180273849Abstract: The invention provides a method, stage and plant for removing LTFT catalyst fines and/or organometallic catalyst compounds from of LTFT wax, downstream from the LTFT reactor. The method includes at least one stage having the steps of causing a differential pressure across a filter element; causing high mechanical shearing and/or centrifugal forces along and/or away from the surface of the filter on the high pressure side of the filter to cause the particles to be continuously removed from the filter surface; and wherein the differential pressure is selected to be sufficient to force flow of the wax across the filter to cause filtration.Type: ApplicationFiled: January 20, 2016Publication date: September 27, 2018Inventors: Marc BRUESCHKE, Manfred RUPPEL, Eva Alonso MUSLERA, Pal SORAKER

Patent number: 9278891Abstract: A system for a Fischer-Tropsch synthesis using a three-phase reactor in which a primary filter removes coarse catalyst particles from the product and in which catalyst fines are removed in a secondary filter. Some or all portion of the product wax from the secondary filter can be recycled back to the reactor, either as a back flush medium for the primary filter or directly to the slurry in the reactor, whereby removal of catalyst fines is rendered independent of the rate of wax production.Type: GrantFiled: December 8, 2009Date of Patent: March 8, 2016Assignee: GTL.F1 AGInventors: Pal Soraker, Manfred Ruppel, Dag Schanke, Matthias Wagner

Patent number: 9039980Abstract: A slurry bubble column reactor with a gas distribution arrangement comprising an upper sparger, a lower sparger, and an open-ended tube. Gas from the lower sparger enters the tube and lowers the density of slurry in the tube. The difference in slurry density causes the slurry in the tube to rise, causing slurry outside the tube to move down, maintaining circulation and flushing catalyst from the vessel wall.Type: GrantFiled: November 10, 2009Date of Patent: May 26, 2015Assignee: GTL.FI AGInventors: Manfred Ruppel, Thomas Gutermuth, Dag Schanke, Pal Soraker

Patent number: 8980201Abstract: A system and process for removing catalyst fines from a gas stream overhead the slurry in a Fischer-Tropsch slurry bubble column reactor. The gas phase at the top of the slurry bubble column reactor containing small amounts of entrained liquid and catalyst particles. The unreacted gases are passed through a demister, which removes larger droplets and catalyst particles. Smaller droplets and catalyst fines are conveyed to a secondary gas cleaner, such as a cyclone, whereby substantially all remaining particles are removed from the gas phase. A particle-containing liquid produced in the secondary gas cleaner can be further subjected to a filtrate cleaning unit to filter out fine catalyst particles and produce a substantially particle-free liquid product stream and a slurry stream of liquid product containing catalyst particles.Type: GrantFiled: June 22, 2010Date of Patent: March 17, 2015Assignee: GTL.FI AGInventors: Trond Myrstad, Dag Schanke, Pål Søraker, Matthias Wagner, Manfred Ruppel

Patent number: 8778193Abstract: The invention provides a method for the separation of liquid from a three phase slurry bubble column. The method includes the step of charging the inside of a hollow filter element with a rinsing fluid to clean the inside of the filter for catalyst fines followed by a backflushing step. The invention also provides an installation for the separation of liquid from a three phase slurry bubble column. The installation includes at feast one hollow and enclosed filter element and one or more conduits in fluid communication with the internal volume of the filter, with at least one conduit being configured or connected for inflow of rinsing fluid and at least one conduit being configured or connection for outflow of rinsing fluid.Type: GrantFiled: October 2, 2006Date of Patent: July 15, 2014Assignees: Petroleum Oil and Gas Corporation of South Africa, Ltd., Statoil Hydro ASAInventors: Ockert Rudolph Minnie, Patrick Otto Taylor, Pål Søraker, Marcus Fathi

Patent number: 5997826Abstract: A reactor for catalytic dehydrogenation of dehydrogenatable hydrocarbons, in particular C.sub.3 and/or C.sub.4 hydrocarbons, in a hydrocarbon-containing stream, with selective oxidation of hydrogen. The reactor comprises serially connected in the flow direction of the hydrocarbon-containing stream: a first catalyst zone (2), an oxygen admixing zone (3) provided with a means (5) for separate feeding of an oxygen-containing gas into the hydrocarbon-containing stream, and a second catalyst zone (4). The oxygen admixing zone (3) has a cross section area in the flow direction of the hydrocarbon-containing stream which is from 0.5% to 75% of the cross section area of each of the two catalysts zones (2, 4), so as to obtain a higher flow velocity in the oxygen-admixing zone (3) than in the catalyst zones.Type: GrantFiled: August 5, 1997Date of Patent: December 7, 1999Assignee: Den norske stats oljeselskap a.s.Inventors: Rune Lodeng, Pal Soraker
