Patent number: 9273607Abstract: A system may include a compressor, a heat exchanger and an ITM. The compressor is configured to receive an air stream and compress the air stream to generate a pressurized stream. The heat exchanger is configured to receive the pressured stream and indirectly heat the pressurized stream using heat from an oxygen stream from an Ion Transport Membrane (ITM). The ITM is configured to receive the heated pressurized stream and generate an oxygen stream and the non-permeate stream, wherein the non-permeate stream is passed to a gas turbine burner and the oxygen stream is passed to the heat exchanger.Type: GrantFiled: May 31, 2013Date of Patent: March 1, 2016Assignee: GTLpetrol LLCInventor: Rodney J. Allam

Patent number: 9169778Abstract: A hydrogen rich fuel gas for a gas turbine ballasted with nitrogen and steam can be produced and superheated to a temperature above its dew point. The fuel gas may have a minimal or reduced content of CO2 or fuel components CO and CH4 which contain carbon so that when combusted in a suitable gas turbine there may be minimal or reduced emissions of CO2 to the atmosphere. These example methods may result in a capture of the bulk of the carbon present in the total natural gas feed as CO2 compressed to pipeline delivery pressure for sequestration.Type: GrantFiled: June 3, 2014Date of Patent: October 27, 2015Assignee: GTLpetrol LLCInventor: Rodney J. Allam

Patent number: 9011814Abstract: Reactive diluent fluid (22) is introduced into a stream of synthesis gas (or “syngas”) produced in a heat-generating unit such as a partial oxidation (“POX”) reactor (12) to cool the syngas and form a mixture of cooled syngas and reactive diluent fluid. Carbon dioxide and/or carbon components and/or hydrogen in the mixture of cooled syngas and reactive diluent fluid is reacted (26) with at least a portion of the reactive diluent fluid in the mixture to produce carbon monoxide-enriched and/or solid carbon depleted syngas which is fed into a secondary reformer unit (30) such as an enhanced heat transfer reformer in a heat exchange reformer process. An advantage of the invention is that problems with the mechanical integrity of the secondary unit arising from the high temperature of the syngas from the heat-generating unit are avoided.Type: GrantFiled: February 22, 2013Date of Patent: April 21, 2015Assignee: GTLpetrol LLCInventors: Shoou-I Wang, John Michael Repasky, Shankar Nataraj, Xiang-Dong Peng
