摘要： According to a first step in an air separation unit, all the air intended for distillation is compressed in a main compressor (1), a first stream of air, compressed in at least the main compressor, purified and cooled in a heat exchange line (6), is sent to the medium-pressure column (8) of a double column, said stream of air is divided into a nitrogen-enriched stream and an oxygen-enriched stream in the medium-pressure column, a liquid oxygen stream (16) is withdrawn from the low-pressure column, said stream is pressurized up to a high pressure and vaporized in the heat exchange line in order to form a first high-pressure oxygen-rich gas stream, at least one portion (24) of the air compressed in the main compressor is liquefied and the liquefied portion is sent to the double column, and a second oxygen-rich gas stream (115) is also produced, but at a lower pressure than the first oxygen-rich gas stream, and, in a second step, the air liquefaction pressure is increased by adjusting the blades of the main compressor (1), which set this pressure, the production of the second oxygen-rich gas stream is reduced, and the withdrawal of the first oxygen-rich gas stream is increased.

SOLUTION: The air distilling plant 1 comprises three assemblies including one juxtaposed to others wherein the first assembly 10 comprises an intermediate pressure column 2 and a vaporizer/condenser 4 disposed on top thereof, the second assembly 11 comprises a low pressure column 3 and a pump 6 and the third assembly 12 comprises a main heat exchange line 5. A duct 18 transports gaseous nitrogen from the head section of the intermediate pressure column 2 to the upper inlet of the vaporizer/condenser 4. A duct 19 returns condensed nitrogen from the lower outlet of the vaporizer/condenser 4 to the head section of the column 2. Liquid nitrogen to be vaporized is led out from the base section of the low pressure column 3 and transported through a duct 20 provided wit the pump 6 to the upper inlet of the vaporizer/condenser 4.
