The heat recovery steam generator may include a diverted water flow in communication with the recirculation heat exchanger. | 10-27-2011 |
20110271689 | GAS TURBINE COOLING - In one embodiment, a compressor discharge casing of a gas turbine engine is designed to receive discharge air from a compressor and to direct a first portion of the discharge air into a combustor of the gas turbine engine and a second portion of the discharge air into a nozzle assembly of a gas turbine to cool components of the gas turbine. A heat transfer device is configured to receive a cooling fluid and to cool the second portion of the discharge air with the cooling fluid. | 11-10-2011 |
20120174621 | CARBON DIOXIDE LIQUEFACTION SYSTEM - Systems are disclosed herein for enhancing energy usage while pressurizing a carbonaceous gas. Such systems include a carbon dioxide (CO | 07-12-2012 |
20130186101 | METHOD OF USING EXTERNAL FLUID FOR COOLING HIGH TEMPERATURE COMPONENTS OF GAS TURBINE FOR A PROCESS POWER PLANT - An external fluid in a closed loop is used to cool hot gas path components of gas turbine. After cooling the turbine components, the heated external fluid is dumped either in the compressor discharge casing or in the one of the turbine's stages. Where the external fluid is nitrogen to be dumped in the turbine compressor's discharge casing, the nitrogen is compressed using diluent nitrogen compressors. Alternatively, where the external fluid is nitrogen to be dumped in one of the stages of the turbine, the nitrogen is not compressed at all. The turbine blade heat exchangers in the turbine stages through which the nitrogen passes can be connected in parallel or in series for cooling the hot gas path components in the turbine stages. The nitrogen can optionally be mixed with air or steam or not mixed at all. | 07-25-2013 |
20140026572 | SYSTEM AND METHOD FOR CAPTURING CARBON DIOXIDE FROM SHIFTED SYNGAS - A system for capturing carbon dioxide from a shifted syngas is disclosed. The system may generally include a solid sorbent configured to absorb carbon dioxide at a first temperature and release carbon dioxide at a second temperature. In addition, the system may include an absorption chamber configured to receive the shifted syngas at the first temperature and a regeneration chamber separate from the absorption chamber. The regeneration chamber may be maintained at the second temperature. The solid sorbent may be cycled between the absorption chamber and the regeneration chamber such that carbon dioxide from the shifted syngas is absorbed within the absorption chamber to produce a decarbonized fuel gas and released within the regeneration chamber to produce a carbon dioxide stream. | 01-30-2014 |
20140026751 | SYSTEM AND METHOD FOR CAPTURING CARBON DIOXIDE FROM FLUE GAS - A system for capturing carbon dioxide from flue gas exhausted from a burner. The system may generally include a solid sorbent configured to absorb carbon dioxide at a first temperature and release carbon dioxide at a second temperature. In addition, the system may include a flue gas passage defining a flow path for the flue gas exhausted from the burner. The flow path may include an absorption zone in which the flue gas is at the first temperature and a regeneration zone in which the flue gas is at the second temperature. The solid sorbent may be cycled between the absorption zone and the regeneration zone such that carbon dioxide from the flue gas is absorbed by the solid sorbent within the absorption zone and released by the solid sorbent within the regeneration zone. | 01-30-2014 |
20140116023 | POWER PLANT EMISSIONS REDUCTION - A system for improved emissions performance of a power plant generally includes an exhaust gas recirculation system having an exhaust gas compressor disposed downstream from the combustor, a condensation collection system at least partially disposed upstream from the exhaust gas compressor, and a mixing chamber in fluid communication with the exhaust gas compressor and the condensation collection system, where the mixing chamber is in fluid communication with the combustor. | 05-01-2014 |
20140182300 | SYSTEM AND METHOD FOR CO2 CAPTURE WITH H2 MEMBRANE INTEGRATED WITH WARM SULFUR REMOVAL TECHNOLOGY - A method and system for capturing and isolating carbon dioxide and hydrogen gases from a high temperature synthesis gas stream containing a substantial amount of CO and sulfur compounds for use as a “clean” supplemental fuel, comprising the steps of reducing the temperature of the high temperature synthesis gas stream, removing substantially all of the sulfur compounds present in the synthesis gas, converting a first portion of CO to carbon dioxide in a first high temperature water-gas shift reaction, converting a second portion of CO to carbon dioxide using a second low temperature water-gas shift reaction, converting a third portion of CO to carbon dioxide using a third low temperature water-gas shift reaction and then separating out substantially all hydrogen present in the treated synthesis gas stream. | 07-03-2014 |
