| 20090064581 | PLASMA-ASSISTED WASTE GASIFICATION SYSTEM - A plasma-assisted waste gasification system and process for converting waste stream reaction residues into a clean synthesis gas (syngas) is disclosed. The feedstock is fed into a reactor roughly one-third from the bottom through the use of a feed mechanism. The reactor has three zones; a bottom zone where melting occurs, a middle zone where gasification takes place, and a top zone with integrated plasma torches to control the temperature and polish the syngas. The residence times in the three zones are selected to optimize the syngas composition and melted products. The syngas leaves the reactor and is partially quenched with relatively cooler synthesis gas. The partially quenched syngas is further cooled to recover heat for steam generation and/or preheating the waste stream to the reactor. The cold syngas is then processed to remove pollutants. The clean synthesis gas is combusted in power generation equipment to generate electricity, or converted to other fuels by chemical processes. | 03-12-2009 |
| 20090193809 | METHOD AND SYSTEM TO FACILITATE COMBINED CYCLE WORKING FLUID MODIFICATION AND COMBUSTION THEREOF - A method of assembling a combustion system includes providing a gas turbine engine that includes a gas turbine section coupled downstream from a combustion chamber and coupling a source of oxygen to the gas turbine engine such that a stream of oxygen discharged from the source facilitates displacing nitrogen in the working fluid of the gas turbine engine and facilitates decreasing emissions generated within the gas turbine engine. | 08-06-2009 |

| 20110245937 | SYSTEM AND METHOD FOR INTEROPERABILITY BETWEEN CARBON CAPTURE SYSTEM, CARBON EMISSION SYSTEM, CARBON TRANSPORT SYSTEM, AND CARBON USAGE SYSTEM - Systems and methods are disclosed herein for enhancing interoperability of a plant. Such systems and methods include a carbon emission, capture, transport, and usage model. The carbon emission, capture, transport, and usage model is capable of modeling interrelationships of inputs, outputs, and requirements between a carbon emitting plant, the carbon capture process, a carbon transportation system, and a carbon usage system. The carbon emitting plant is capable of producing a product having a carbonaceous substance. The carbon capture process is capable of capturing at least a portion of the carbonaceous substance from the product as a carbonaceous gas. The carbon transportation system is capable of transporting the carbonaceous gas from the carbon capture process to the carbon usage system. The carbon usage system is capable of receiving the carbonaceous gas transported by the carbon transportation system. | 10-06-2011 |
| 20110266726 | GAS TURBINE EXHAUST AS HOT BLAST FOR A BLAST FURNACE - In certain exemplary embodiments, a system includes a gas turbine system having a turbine, combustor, and a compressor.

| 20120063957 | SYSTEM FOR PRESSURIZING FEEDSTOCK FOR FIXED BED REACTOR - In accordance with one embodiment, a system includes a posimetric pump configured to increase pressure of a feedstock to provide a pressurized feedstock. The system also includes a fixed bed gasifier configured to gasify the pressurized feedstock, wherein the fixed bed gasifier comprises an enclosure, a feedstock inlet configured to receive the pressurized feedstock, at least one agent inlet configured to receive at least one gasification agent, a syngas outlet configured to output a syngas, an ash outlet configured to output ash, and a fixed bed configured to support the pressurized feedstock while allowing flow of the at least one gasification agent through the pressurized feedstock. | 03-15-2012 |
| 20120111021 | Integrated Turbomachine Oxygen Plant - An integrated turbomachine oxygen plant includes a turbomachine and an air separation unit. One or more compressor pathways flow compressed air from a compressor through one or more of a combustor and a turbine expander to cool the combustor and/or the turbine expander. An air separation unit is operably connected to the one or more compressor pathways and is configured to separate the compressed air into oxygen and oxygen-depleted air. A method of air separation in an integrated turbomachine oxygen plant includes compressing a flow of air in a compressor of a turbomachine. The compressed flow of air is flowed through one or more of a combustor and a turbine expander of the turbomachine to cool the combustor and/or the turbine expander. The compressed flow of air is directed to an air separation unit and is separated into oxygen and oxygen-depleted air. | 05-10-2012 |
