Integrated air-separation process and plant, including at least two air separation units (1, 101), an air compressor (13), which feeds a combustion chamber and at least one of the air separation units with compressed air, and at least one dedicated air compressor (21, 121) feeding one or both of the
Integrated air-separation process and plant, including at least two air separation units (1, 101), an air compressor (13), which feeds a combustion chamber and at least one of the air separation units with compressed air, and at least one dedicated air compressor (21, 121) feeding one or both of the air separation units, so that, if both air separation units receive air from the compressor (13), the proportions of air coming from the air compressor are different in the case of the two air separation units.
