<p>The method involves compressing feed air in a main air compressor (3) at certain pressure. A portion of the compressed feed air is cooled in a main heat exchanger system (40) in indirect heat exchange against a return flow (64,71,79,81) from a distillation column system (50,51). A primary air flow (9,10) and a secondary air flow (20,21) are diverted from the compressed feed air. The secondary air flow is compressed from the former pressure to another pressure higher than the former pressure in a secondary compression system, where the secondary compression system is adiabatically designed. An independent claim is included for a device for generating a gaseous oxygen pressurized product by cryogenic separation of air.</p> |
