Abstract:
In a plant for separating air which does not comprise an argon column, an intermediate-pressure column (102) has a bottom reboiler (24) which is heated by a gas (233) coming from the low-pressure column (103). The intermediate-pressure column is fed from the high-pressure column (101). This makes it possible to reduce the energy consumption while improving the efficiency of the process.
