Abstract (en)

[origin: EP2503269A1] The device has a main heat exchanger (6) comprising two heat exchanger-blocks, and a distillation column-system (5) for separating nitrogen and oxygen. A supercooling-heat exchanger (2) is separated from the main heat exchanger. A conduit (16) conducts gas flow from the column-system to the supercooling-heat exchanger, where the main and supercooling-heat exchangers are arranged in a coldbox. An upper end of the supercooling-heat exchanger is arranged below a lower end of the main heat exchanger. The supercooling-heat exchanger is suspended at the main heat exchanger over pipelines (17-19).
