Abstract

See full text

The invention relates to an apparatus for the low-temperature separation of air and comprises a main heat exchanger (6) having at least two heat-exchanger blocks, a distillation column system for nitrogen-oxygen separation (5) having at least one high-pressure column, a subcooling-counterflow heat exchanger (2), means for introducing feed air via the main heat exchanger (6) into the high-pressure column, means for introducing a liquid stream from the distillation column system into the subcooling-counterflow heat exchanger (2), and means for introducing a gas stream (16) from the distillation column system into the subcooling-counterflow heat exchanger (2). The main heat exchanger (6) and the subcooling-counterflow heat exchanger (2) are arranged in a first cold box (12), and the subcooling-counterflow heat exchanger (2) is suspended from the main heat exchanger (6).
