A cryogenic rectification system wherein oxygen-enriched liquid from a higher pressure column is vaporized against condensing nitrogen-containing fluid which is employed as additional reflux in the lower pressure column thus increasing the column L/V ratio and the product recovery.

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.

A method and backup system for backing up a supply oxygen in an air separation plant in which during normal operation, a stream of oxygen-rich liquid is pumped through a main flow path, extending from a surge tank to a heat exchanger, to deliver an oxygen product. The surge tank receives the oxygen-rich liquid from a bottom region of the lower pressure column of the plant. Additionally, during normal operations, a stream of the oxygen-rich liquid is also introduced to a reserve storage tank through a backup flow path. During a transient operation, where the air separation plant has ceased operation, the surge tank is isolated and liquid is pumped from the surge tank through an auxiliary flow path to an auxiliary vaporizer to continue the supply of the oxygen product and the surge tank is replenished with oxygen-rich liquid previously stored in the reserve storage tank.
