417 53, 417248

Abstract:

This disclosure is directed to a novel arrangement for equipment used to compress fluids. A single prime mover is connected to a plurality of compressors.

US Classification:

290 1 R, 166302, 166265, 40512935, 1662721, 166 52

Abstract:

A method for in situ heating of a subsurface formation is provided. The method includes receiving hydrocarbon fluids produced from the subsurface formation as a result of heating. The method also includes processing the produced fluids to generate a hydrocarbon stream. A portion of the hydrocarbon stream is then delivered to a combustor along with an oxygen-containing stream as a combustion mixture. A diluent gas stream may also be provided for cooling. The mixture is then combusted to generate electricity, and to release an exhaust stream comprising carbon dioxide. The method also includes using at least a portion of the exhaust gas stream generated from the combustion for injection or for sequestration, thereby minimizing atmospheric release. In addition, at least a portion of the electrical power is delivered to a plurality of electrically resistive heating elements to deliver heat to the subsurface formation. A low emission power generation system is also provided.

International Classification:

F02C 3/34
F02C 7/141

US Classification:

60772, 60 3952, 60726, 60728

Abstract:

Systems, methods, and apparatus are provided for controlling the oxidant feed in low emission turbine systems to maintain stoichiometric or substantially stoichiometric combustion conditions. In one or more embodiments, such control is achieved by diverting a portion of the recirculating exhaust gas and combining it with the oxidant feed to maintain a constant oxygen level in the combined oxidant-exhaust stream fed to the combustion chamber.

US Classification:

60773, 60 3919

Abstract:

Systems, methods, and apparatus are provided for controlling the oxidant feed in low emission turbine systems to maintain stoichiometric or substantially stoichiometric combustion conditions. In one or more embodiments, such control is achieved through methods or systems that ensure delivery of a consistent mass flow rate of oxidant to the combustion chamber.

US Classification:

60783, 60784

Abstract:

Systems, methods, and apparatus are provided for generating power in low emission turbine systems and separating the exhaust into rich COand lean COstreams. In one or more embodiments, the exhaust is separated at an elevated pressure, such as between a high-pressure expansion stage and a low-pressure expansion stage.
