Definitions
- an air separation process using an apparatus comprising at least one medium pressure column, a low pressure column thermally connected with the low medium pressure column and a mixing column operating at a pressure above the pressure of the medium pressure column in which i) compressed and purified air is sent to the medium pressure column ii) flows enriched in nitrogen and oxygen from the medium pressure column to the column low pressure iii) an oxygen-enriched liquid is sent from the low-pressure column to the head of the mixing column iv) an oxygen-enriched gas is drawn off from the head of the mixing column characterized in that a liquid flow enriched in nitrogen from the medium pressure column, it is pressurized, it is vaporized at least partially and the tank of the mixing column is supplied with at least part of the vapor liquid Orise.
