Process and device for the production of at least one gaseous high pressure fluid such as Oxygen, Nitrogen or Argon by cryogenic separation of air

摘要

The procedure consists of passing all the air to be distilled through a compressor (1), purifying the compressed air, and subjecting at least part of it to increased pressure. The compressed and purified air is passed through a heat exchange line (6), where it is cooled, followed by separation in distillation columns (8, 9).
