ABSTRACT:
In a process for the cryogenic separation of air and recovery of argon in a distillation system having at least one distillation column that produces a nitrogen-enriched stream, an oxygen enriched stream, and an argon-enriched stream, and at least one sidearm column which receives the argon-enriched stream from the distillation column, controlling argon recovery by manipulating the total amount of argon inventory within the system at a given time.
