Abstract: A method for separating air is provided, in which a flow of oxygen-rich liquid is sent to a top of a pure oxygen column, having a pure oxygen reboiler, in which said flow is purified in order to form a vessel liquid containing at least 98 mol % of oxygen and the vessel liquid is drawn off as a product. A supercharged airflow at a second pressure is sent to the pure oxygen reboiler and to a liquid oxygen vaporizer; a nitrogen-rich gas is drawn from the top of the medium-pressure column and sent to an intermediate reboiler of the low-pressure column and the condensed gas is sent to the top of the medium-pressure column; and a nitrogen-rich gas or air is sent to a vessel reboiler of the low-pressure column and the liquid that condenses therein is sent to the medium-pressure column.

Abstract: In a plant for separating air which does not comprise an argon column, an intermediate-pressure column (102) has a bottom reboiler (24) which is heated by a gas (233) coming from the low-pressure column (103). The intermediate-pressure column is fed from the high-pressure column (101). This makes it possible to reduce the energy consumption while improving the efficiency of the process.

Abstract: A plant for the separation of air includes at least three columns, including an auxiliary column and two other columns, of which at least one is fed with air and of which that operating at the lowest pressure operates between 2 and 10 bar. A flow between 40 and 95 mol % of argon originating from the auxiliary column is optionally mixed with a gas enriched in nitrogen from the column operating at the lowest pressure. The auxiliary column operates at the same pressure as the column from which it is fed.

Abstract: In a method for separating air in a column system, by cryogenic distillation, compressed, purified and cooled air is separated in the column system in order to form an oxygen-enriched flow and a nitrogen-enriched flow. At least one column of the column system contains a vaporizer-condenser for ensuring the vaporization of a liquid enriched in oxygen in relation to the air by means of heat exchange with a calorigenic fluid, the calorigenic fluid having been compressed upstream of the vaporizer-condenser in a compressor having a cryogenic inlet temperature, the calorigenic fluid being at least partially condensed in the vaporizer-condenser, and a cryogenic liquid is added to the calorigenic fluid upstream of the vaporizer-condenser.

Abstract: In a process for delivering pressurized gas from an apparatus for separating air by cryogenic distillation, a stream of oxygen-rich liquid or gas having a nominal flow rate is withdrawn from a low-pressure column, an oxygen-rich liquid purge stream is withdrawn as bottoms from the low-pressure column and the oxygen-rich liquid purge stream is sent to a storage tank, in the event of a reduction in the production by the column system or an increase in the demand by a customer, a back-up stream is withdrawn from the storage tank and vaporized in a back-up reboiler and only if the liquid level in the storage tank exceeds a given threshold, a liquid stream is withdrawn from the storage tank constituting at most 2% of the nominal production output of the oxygen-rich stream and is sent to the back-up reboiler.
