Abstract (en)

[origin: EP1199532A1] Process for low temperature decomposition of air is carried out in a three column system consisting of a high pressure column (1), a middle pressure column (2) and a low pressure column (3). Process for low temperature decomposition of air comprises: (i) compressing a first air stream (10, 14, 15, 16) in a gas turbine compressor (11), purifying, cooling and feeding to the high pressure column; (ii) compressing a second air stream in an air compressor (21) operated by the gas turbine, purifying, cooling and feeding to the middle pressure column; (iii) producing a first oxygen-enriched fraction (53, 54) in the high pressure column; (iv) feeding the first oxygen-enriched fraction to the middle pressure column; and (v) feeding a second oxygen-enriched fraction (57) from the middle pressure column to the low pressure column. An Independent claim is also included for a device for carrying out the low temperature decomposition of air.
