Abstract (en)
An air separation plant includes a plurality of rectification columns comprising a higher pressure column 44 and a lower pressure column 46; a first train 2 of air compression stages 4, 6, 8 and 10 communicating with the higher pressure column 44, and a second train 18 of air compression stages 24, 26 which form part of a gas turbine 16 and which communicate via an expansion turbine 41 with at least one of the rectification columns 44 and 46. The first train 2 of air compression stages 4, 6, 8 and 10 does not form part of the gas turbine 16 or any other gas turbine. The higher approve column 44 is able to be operated at a pressure that can be set independently of the gas turbine 16. <IMAGE>
