Patent number: 10683801Abstract: A system includes a gas turbine system having a turbine combustor, a turbine driven by combustion products from the turbine combustor, and an exhaust gas compressor driven by the turbine. The exhaust gas compressor is configured to compress and supply an exhaust gas to the turbine combustor. The gas turbine system also has an exhaust gas recirculation (EGR) system. The EGR system is configured to recirculate the exhaust gas along an exhaust recirculation path from the turbine to the exhaust gas compressor. The system further includes a main oxidant compression system having one or more oxidant compressors. The one or more oxidant compressors are separate from the exhaust gas compressor, and the one or more oxidant compressors are configured to supply all compressed oxidant utilized by the turbine combustor in generating the combustion products.Type: GrantFiled: March 13, 2017Date of Patent: June 16, 2020Assignees: General Electric Company, ExxonMobil Upstream Research CompanyInventors: Richard A. Huntington, Franklin F. Mittricker, Loren K. Starcher, Sulabh K. Dhanuka, Dennis M. O'Dea, Samuel D. Draper, Christian M. Hansen, Todd Denman, James A. West

Patent number: 9863267Abstract: A system includes plurality of combustors and a distributed flow measurement system coupled to the plurality of combustors. Each combustor of the plurality of combustors includes one or more oxidant passages and one or more fuel passages. The distributed flow measurement system is configured to measure an oxidant flow rate for a respective oxidant passage of the one or more oxidant passages of the respective combustor based at least in part on an oxidant pressure drop along the respective oxidant passage, and the distributed flow measurement system is configured to measure a fuel flow rate for a respective fuel passage of the one or more fuel passages of the respective combustor based at least in part on a fuel pressure drop along the respective fuel passage.Type: GrantFiled: January 19, 2015Date of Patent: January 9, 2018Assignees: General Electric Company, ExxonMobil Upstream Research CompanyInventors: Dennis M. O'Dea, Karl Dean Minto, Richard A. Huntington, Sulabh K. Dhanuka, Franklin F. Mittricker

Patent number: 9689309Abstract: Systems, methods, and apparatus are provided for generating power in combined low emission turbine systems and capturing and recovering carbon dioxide from the exhaust. In one or more embodiments, the exhaust from multiple turbine systems is combined, cooled, compressed, and separated to yield a carbon dioxide-containing effluent stream and a nitrogen-containing product stream. Portions of the recycled exhaust streams and the product streams may be used as diluents to regulate combustion in each combustor of the turbine systems.Type: GrantFiled: March 5, 2012Date of Patent: June 27, 2017Assignee: ExxonMobil Upstream Research CompanyInventors: Russell H.

Patent number: 9353940Abstract: Systems and methods for an oxy-fuel type combustion reaction are provided. In one or more embodiments, a combustion system can include at least two mixing zones, where a first mixing zone at least partially mixes oxygen and carbon dioxide to produce a first mixture and a second mixing zone at least partially mixes the first mixture with a fuel to produce a second mixture. The combustion system can also include a combustion zone configured to combust the second mixture to produce a combustion product. In one or more embodiments, the first mixture can have a spatially varied ratio of oxygen-to-carbon dioxide configured to generate a hot zone in the combustion zone to increase flame stability in the combustion zone.Type: GrantFiled: June 3, 2010Date of Patent: May 31, 2016Assignees: ExxonMobil Upstream Research Company, Georgia Tech Research CorporationInventors: Franklin F.
