초록

A method of power production using a high pressure/low pressure ratio Brayton Power cycle with predominantly N2 mixed with CO2 and H2O combustion products as the working fluid is provided. The high pressure can be in the range 80 bar to 500 bar. The pressure ratio can be in the range 1.5 to 10. The natural gas fuel can be burned in a first high pressure combustor with a near stoichiometric quantity of pressurized preheated air and the net combustion gas can be mixed with a heated high pressure recycle N2+CO2+H2O stream which moderates the mixed gas tempe...

1. A method for producing power, comprising: combusting a first fuel stream and a first air stream in a first combustor in the presence of a first recycle stream to produce a first combustion stream; expanding the first combustion stream in a first turbine to rotate the first turbine and produce power; directing at least a portion of a first discharge stream from the first turbine to a first heat exchanger; employing the portion of the first discharge stream to heat the first air stream and at least a portion of the first recycle stream that is produced ...
