Selected exhaust gases are fed back into the gas turbine compressor so as to establish a stable mixture of working fluid constituents for the gas turbine. The gas turbine is preferably configured in a combined cycle arrangement and both mechanical and thermal energy is extracted from the flow of gases through the load turbine, this energy being used in the production of useful process fluids. The methods and apparatus of the present invention are particularly unique in that here the principal output of the combined cycle plant is not electrical energy but rather valuable chemical products. In short, the gas turbine is being employed as a high-temperature reactor from which both mechanical and thermal energy may be extracted as a result of the energy in the gaseous reaction products.Other References
