摘要： A method for separating carbon dioxide (CO2) from a gas stream is disclosed, in which the gas stream is reacted with a lean aminosilicone solvent in an absorber, resulting in a rich aminosilicone solvent that is then treated in a desorber to release the CO2 and regenerate lean aminosilicone solvent in a desorption reaction. The regenerated solvent is directed into a steam-producing, indirect heat exchanger that is configured to supply steam to the desorber at a temperature high enough to augment the desorption reaction. Also, selected amounts of make-up water are added to the rich aminosilicone solvent at one or more process locations between the absorber and the desorber, to lower the viscosity of the solvent and to lower the temperature required for the desorption reaction.

摘要： A fuel injector is provided and includes a surface disposed proximate to a flow of a first fluid and a delta wing feature. The surface has upstream and downstream portions defined relative to the flow and defines an injector hole in the downstream portion by which a jet of a second fluid is injectable into the flow. The delta wing feature is disposed on the surface at the upstream portion and is configured to lift an oncoming portion of the flow off the surface and to cause the oncoming portion of the flow to form a pair of counter-rotating vortices that respectively co-rotate with the jet in a cross-flow direction.

摘要： A fuel nozzle system for enabling a gas turbine to start and operate on low-Btu fuel includes a primary tip having primary fuel orifices and a primary fuel passage in fluid communication with the primary fuel orifices, and a fuel circuit capable of controlling flow rates of a first and second low-Btu fuel gases flowing into the fuel nozzle. The system is capable of operating at an ignition status, in which at least the first low-Btu fuel gas is fed to the primary fuel orifices and ignited to start the gas turbine, and a baseload status, in which at least the second low-Btu fuel gas is fired at baseload. The low-Btu fuel gas ignited at the ignition status has a content of the first low-Btu fuel gas higher than that of the low-Btu fuel gas fired at the baseload status. Methods for using the system are also provided.
