Abstract (en)
[origin: US2001003909A1] In an apparatus for the separation of air by cryogenic distillation, the overhead gas of a mixing column is sent to the passages for warming a bottom reboiler of the low-pressure column of a double column fed with air to be distilled. This increases the production of oxygen in the bottom of the low-pressure column.
