ABSTRACT:
An apparatus and method for air distillation. Two cold boxes and an air treatment unit are used to distill air. The cold boxes contain a heat exchanger for cooling the air to be distilled and an air distillation unit for producing either oxygen, nitrogen or argon. The air treatment unit has many individual treatment elements which are connected in parallel. The outlet of the air treatment unit is connected to both cold boxes and to all the individual treatment units.
