Abstract (en)
[origin: EP0605262A1] According to this process, which employs a double air distillation column (5): - the low-pressure column (7) is operated under a pressure which is markedly greater than atmospheric pressure, in particular of the order of from 2 to 5 bar, and the medium-pressure column (6) is operated under a corresponding pressure, in particular of the order of from 8 to 16 bar; - the production gaseous oxygen is directly recovered in the tank of the low-pressure column, and - the apparatus is kept cold, at least partly, by free expansion of at least one gaseous product leaving the low-pressure column. Application to the production of gaseous oxygen under a pressure of a few bar. <IMAGE>
