Process and apparatus for the cryogenic separation of air |
| abstract |
The method and the device are used for the low-temperature separation of air. Compressed and pre-cleaned feed air (3, 5) is introduced into a rectification system for nitrogen-oxygen separation, which has a pressure column (6). At least part of the compressed and pre-cleaned feed air is fed to the pressure column (6) (5). An oxygen-enriched fraction (13) is removed from the pressure column (6) and fed to a further work step (7) within the rectification system (14). The oxygen-enriched fraction (13) is removed from at least one theoretical or practical base (15) above the point at which compressed and pre-cleaned feed air (5) is fed to the pressure column. A rinsing fraction (16) is removed in liquid form from the bottom of the pressure column (6), fed in liquid form to a cleaning stage (17) in which N 2 O is removed, and is removed from the cleaning stage (17) as a cleaned rinsing fraction (18). |
