ABSTRACT:
A gas turbine/air separation apparatus operates at both a design point and a turndown point and includes a gas turbine for providing pressurized air and an air separation plant which receives the pressurized air. The air separation plant produces an oxygen-bearing fluid at a first purity and first pressure when the pressurized air is at a design point pressure, and produces the oxygen-bearing fluid at a second purity and second pressure when the pressurized air is at a turndown pressure, the second purity and second pressure being lower than the first purity and first pressure, respectively. A compressor compresses the oxygen-bearing fluid to a design point pressure and feeds the compressed oxygen-bearing fluid to the use point. A controller is responsive to a turndown state for causing the gas turbine to provide the pressurized air at the turndown pressure and causes the air separation plant to respond thereto by producing and supplying the oxygen-bearing fluid at the second purity and second pressure to the compressor means.
