ABSTRACT:
The invention concerns a method involving the intake (through16) of air in an intake of an air separation plant (14), supplying (though16) at least a fraction of the intake air from a gas turbine compressor section (2), and extracting from the air separation plant (16) two gas streams (through20, 24, 32, and36) respectively nitrogen-enriched and oxygen-enriched streams; detecting (through18) a substantial decrease in the flow rate of the air fraction from the gas turbine compressor section (2), then recycling (through28, 42), to the inlet of the air separation plant (14) at least part of one of the two gas streams, and thus avoiding any major fluctuation of the intake air flow rate of said air separation plant.
