ABSTRACT:
To meet the requirement of a variable demand of gaseous oxygen, a constant flow of liquid oxygen is sent from the double distillation column into a container, and a variable flow of liquid oxygen is withdrawn therefrom, which is thereafter vaporized in a heat exchanger by condensation of a corresponding flow of incoming air. The liquefied air is stored in a second container, from which a constant flow of liquefied air is sent into the double column.
