Abstract (en)
[origin: WO2009021350A1] A process for the production of at least one liquid product (53, 71) and at least one gaseous product (55, 61) by cryogenic distillation is disclosed , according to the first mode, at least part of the feed air is removed from an intermediate point of the heat exchange line (19) , compressed at a cryogenic temperature in a cold compressor (37) and sent to the heat exchange line (19) to be further cooled and sent to the column system (65, 67) and part of the feed air is sent to a first expander (39) and according to the second mode, all of the feed air is compressed to a high pressure at least 20 bars higher than the highest column pressure of the column system (65, 67) in a second compressor (11, 17) , cooled in the heat exchange line (19) and sent in part to a column system (65, 67), another part of the high pressure air being sent to the second expander (29) .
