Abstract (en)
[origin: WO2020128205A1] An apparatus for separating air, comprising a double column (K3, K4), means (B) for sending air to the purification unit at a pressure that is no more than 1 bar higher than atmospheric pressure, a pipe for sending a first air flow (8), which has been purified in the purification unit, to the heat exchanger at a fourth pressure that is no more than 1 bar higher than the second pressure, a pipe for sending the first purified air flow, which has been cooled in the heat exchanger, to the second column for separation, and a booster compressor (E), the apparatus not comprising any means for depressurising the first flow.
