Abstract (en)
[origin: WO2012127148A2] Device for separating air comprises a pipe for withdrawing liquid oxygen from the low-pressure column and for sending it to a first pump (39), a pipe for sending liquid oxygen that has been pressurized to a pressure of below 9 bar abs from the first pump to a vaporizer (41), a pipe for sending gaseous oxygen from the vaporizer to a main exchanger (21) where it is heated up, a pipe for sending liquid oxygen for purging from the vaporizer to a second pump (63) to pressurize it and a pipe for sending the pressurized oxygen from the second pump to an exchanger where it vaporizes to form gaseous oxygen.
