An integrated system, comprising: a first gas turbine system having a first combustion chamber configured to receive and combust a first compressed oxidant and a first fuel in the presence of a compressed recycle stream, wherein the volume of the first compressed oxidant and the first fuel received by the first combustion chamber are such that there is stoichiometric combustion in the first combustion chamber and the combustion chamber directs a first discharge stream to a first expander to generate a gaseous exhaust stream and at least partially drive a main compressor; an exhaust gas recirculation system, wherein the main compressor compresses the gaseous exhaust stream and thereby generates a compressed recycle stream, the compressed recycle stream acting as a first diluent to moderate the temperature of the first discharge stream; a CO 2 separator fluidly coupled to the compressed recycle stream via a purge stream, the CO 2 separator generating a CO 2 -rich stream and a residual stream; a second gas turbine system fluidly coupled to the CO 2 separator via the residual stream consisting primarily of nitrogen-rich gas derived from the CO 2 separator, wherein: the second gas turbine system has a second compressor, a second combustion chamber, and a second gas expander; the second compressor is configured to compress a second feed oxidant and generate a second compressed oxidant; the second fuel, the second compressed oxidant and the residual stream are supplied separately to the second combustion chamber; the second combustion chamber is configured to stoichiometrically combust a combination of a second fuel and the second compressed oxidant in order to generate a discharge stream; the residual stream is utilized as a diluent configured to moderate the temperature of the combustion in the second combustion chamber; the second combustion chamber is fluidly coupled to the second gas expander via the second discharge stream; and the second fuel and the second compressed oxidant are supplied from the same sources as the first fuel and the first compressed oxidant, respectively. a first gas turbine system having a first combustion chamber configured to receive and combust a first compressed oxidant and a first fuel in the presence of a compressed recycle stream, wherein the volume of the first compressed oxidant and the first fuel received by the first combustion chamber are such that there is stoichiometric combustion in the first combustion chamber and the combustion chamber directs a first discharge stream to a first expander to generate a gaseous exhaust stream and at least partially drive a main compressor;
