Systems and methods are provided for varying the exhaust gas recycle circuit of low emission gas turbines. In one or more embodiments, the systems and methods incorporate alternatives to the use of a direct contact cooler. In the same or other embodiments, the systems and methods incorporate alternatives intended to reduce or eliminate the erosion or corrosion of compressor blades due to the presence of acidic water droplets in the recycled gas stream.

Methods of varying low emission turbine gas recycle circuits and systems and apparatus related thereto

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.

Systems and methods for controlling stoichiometric combustion in low emission turbine systems

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. A supply conduit with parallel branch conduits directs fluid to be compressed to at least two compressors and parallel output conduits from each compressor are connected to a common output conduit, which directs compressed fluids to at least one additional compressor.

Parallel dynamic compressor arrangement and methods related thereto

Integrated systems and methods for low emission power generation in a hydrocarbon recovery processes are provided. One system includes a control fuel stream, an oxygen stream, a combustion unit, a first power generate on system and a second power generation system. The combustion unit is configured to receive and combust the control fuel stream and the oxygen stream to produce a gaseous combustion stream having carbon dioxide and water. The first power generation system is configured to generate at least one unit of power and a carbon dioxide stream. The second power generation system is configured to receive thermal energy from the gaseous combustion stream and convert the thermal energy into at least one unit of power.
