Abstract

In an integrated method of air separation, a plant includes at least one first air separation unit (1, 101), a first air compressor (13), a first combustion chamber (17), a first expansion turbine (19), a second air compressor (15), a second combustion chamber (23) and a second expansion turbine (25) and a third air compressor (21) in which compressed air is sent from the first air compressor to the first combustion chamber and to the first air separation unit, compressed air is sent from the second air compressor to the second combustion chamber and to the first air separation unit.
