Patent number: 9382115Abstract: Gas-to-liquids processes for treating natural gas, including the steps of subjecting the natural gas to expansion through a flow restrictor so as to undergo cooling through the Joule Thomson effect. The processes then separate the resulting liquids from the remaining natural gas and processing the natural gas to form a synthesis gas. The synthesis gas is subjected to Fischer-Tropsch synthesis and the output from the Fischer-Tropsch synthesis is separated into a hydrocarbon product and an aqueous phase and the aqueous phase is steam stripped to extract the oxygenates which are then injected into the natural gas stream upstream of the flow restrictor.Type: GrantFiled: December 22, 2014Date of Patent: July 5, 2016Assignee: CompactGTL LimitedInventors: Michael Joseph Bowe, Robert Peat, David James West, Philip Hawker

Patent number: 8945488Abstract: A gas-to-liquids process and plant for treating natural gas, in which the natural gas is subjected to expansion through a flow restrictor so as to undergo cooling through the Joule Thomson effect, enables liquids to be separated from the gas stream. The natural gas may be cooled before it reaches the flow restrictor by heat exchange with fluid that has passed through the flow restrictor. This decreases the proportion of longer-chain hydrocarbons in the natural gas, which may simplify subsequent processing, and may enable the size of the plant to be decreased.Type: GrantFiled: April 27, 2011Date of Patent: February 3, 2015Assignee: CompactGTL LimitedInventors: Michael Joseph Bowe, Robert Peat, David James West, Philip Hawker

Publication number: 20130202498Abstract: A reactor defines first and second flow channels within the reactor, the first flow channels and the second flow channels extending in parallel directions along at least the major part of their lengths. A removable non-structural catalyst insert is provided in those channels in which a reaction is to occur, the catalyst insert comprising a plurality of foils bonded together and which subdivide the flow channel into a multiplicity of flow sub-channels. At least one end portion of the catalyst insert is devoid of active catalytic material. The end portion that is devoid of active catalytic material suppresses the reaction in that part of the flow channel, and so reduces the requirement for any thermal transfer at that part of the flow channel.Type: ApplicationFiled: October 3, 2011Publication date: August 8, 2013Applicant: CompactGTL LimitedInventors: Neil Maxted, Robert Peat, Ross Alexander Morgan

Patent number: 8262754Abstract: A compact catalytic reactor (20) comprises a channel for a rapid reaction having an inlet (26) for a gas mixture to undergo the reaction. The channel is provided with two different catalyst structures (32, 34), a first catalyst structure (32) in the vicinity of the inlet (26) and a second catalyst structure (34) further from the inlet, such that a gas mixture supplied to the inlet flows past them both. The first catalyst structure (32) has little catalytic activity for the rapid reaction, whereas the second catalyst structure (34) has catalytic activity for the rapid reaction. This is applicable to combustion of gas mixtures containing hydrogen, for which the first catalyst structure (32) may comprise uncoated oxidized aluminum-containing ferritic steel, while the second catalyst structure (34) may incorporate Pt and/or Pd in an alumina support. Exhaust gases may also be recycled to the inlet (26) to inhibit combustion.Type: GrantFiled: May 3, 2007Date of Patent: September 11, 2012Assignee: CompactGTL plcInventors: David James West, Michael Joseph Bowe, Stuart Leigh Jones, Clive Derek Lee-Tuffnell, Robert Peat

Publication number: 20120142789Abstract: A catalytic reaction module for performing am endothermic reaction, such as steam reforming, including separator blocks. Each reactor defining a multiplicity of first and second flow channels arranged alternately within the block to ensure thermal contact between the first and second flow channels. The reactor blocks may be arranged and connected for series flow of a combustible gas mixture in the first flow channels. The reactor blocks may be arranged and connected for a gas mixture to undergo endothermic reaction in the second flow channels. Catalyst elements are provided within the flow channels and the catalyst may vary between the blocks or within a block. The catalyst may vary in chemical composition, in catalyst loading, or in active catalyst material.Type: ApplicationFiled: August 6, 2010Publication date: June 7, 2012Applicant: Compact GTL plcInventors: Ross Alexander Morgan, Robert Peat, Tuan Quoc Ly

Patent number: 7897119Abstract: A compact catalytic reactor defines a multiplicity of first and second flow channels arranged alternately, the first flow channels being no more than 10 mm deep and providing flow paths for combustible reactants, and containing a catalyst structure (20) to catalyze combustion of the reactants, and having at least one inlet for at least one of the reactants. The first flow channel also includes an insert (40 or 60) adjacent to each inlet, this insert not being catalytic to the combustion reaction; the insert may define gaps which are narrower than the maximum gap size for preventing flame propagation.Type: GrantFiled: April 26, 2007Date of Patent: March 1, 2011Inventors: David James West, Michael Joseph Bowe, Robert Frew Gillespie, Steven Brabon, Robert Peat

Publication number: 20110046245Abstract: A catalytic reaction module (10) for performing an endothermic reaction such as steam methane reforming, includes separate reactor blocks (12), each reactor block defining a multiplicity of first and second flow channels (15, 16) arranged alternately within the block to ensure thermal contact between the first and second flow channels. The reactor blocks (12a, 12b) may be arranged and connected for series flow of a combustible gas mixture in the first flow channels (15) and also of a gas mixture to undergo the endothermic reaction in the second flow channels (16). This enables the combustion process to be carried out in stages, with the option of cooling the combustion gases between stages, and introducing additional fuel and additional air.Type: ApplicationFiled: February 10, 2009Publication date: February 24, 2011Applicant: CompactGTL plcInventors: Michael Joseph Bowe, Clive Derek Lee-Tuffnell, Robert Peat

Publication number: 20030089623Abstract: A sensor for detecting chemical properties of a liquid, for example in an oil well, includes a glass pH electrode (22a) and a reference electrode (22c). The glass electrode (22a) consists of a narrow sensor electrode (30) on the surface of an electrically insulating substrate (20), a layer of glass (36) covering the sensor electrode (30), and two cleaning electrodes (32, 33) one extending along each side of the sensor electrode along its entire sensing length. The cleaning electrodes (32, 33) are not covered by the layer of glass, and are no more than 3 mm apart from each other. Application of a voltage between them generates gas bubbles by electrolysis that dislodge any fouling from the glass electrode (22a). The sensor electrode (30) may be of zigzag form, with the cleaning electrodes (32,33) interdigitated between the successive parts of the zigzag. A hydrophilic membrane (24) of sulphonated microporous PVdF provides further protection against fouling of the electrodes (22) by oil.Type: ApplicationFiled: September 16, 2002Publication date: May 15, 2003Inventors: Robert Peat, Hedley Graham Rhodes, Andrew Derek Turner

Patent number: 6478950Abstract: A sensor module for monitoring chemical properties of oil well fluids comprises at least one electrochemical sensor for a chemcal species, for example to detect pH and chloride ion concentration. A micro-porous barrier separates the electrochemical sensors from the environment of the module, the micro-porous barrier being of a material which is readily wetted by water. Periodic application of a current pulse between the barrier and a counter electrode enables fouling material to be removed from the micron barrier.Type: GrantFiled: October 2, 2000Date of Patent: November 12, 2002Assignee: Accentus PLCInventors: Robert Peat, Paul Antony Harry Fennell
