Abstract (en)

[origin: EP2600090A1] The method involves branching a recycle stream (57) from a liquefied partial flow line (14), where the recycle stream is relaxed in a throttle valve (58) and is warmed in a main heat exchanger (13). The warmed recycle stream (59) is supplied to the partial flow (7) upstream of a booster (10). The supplied air (1) is compressed to an air pressure in a main air compressor (3) and an air booster. The air is compressed to the pressure that is equal to 4 bar higher than the operating pressure of a high pressure column (18) of a distillation column system for the nitrogen-oxygen separation. An independent claim is included for a device for producing pressurized oxygen by the low-temperature fractionation of air.
