| titleOfInvention | Process and apparatus for low-temperature separation of air |
| abstract | The process and the apparatus are used for low-temperature separation of air in a rectifying column system that has a preliminary separation column (10) and a low-pressure column (20). Feed air (1, 3) is introduced (4, 6, 7, 8, 41) into preliminary separation column (10) and is separated into a nitrogen-enriched overhead fraction and an oxygen-enriched bottom fraction. At least a portion (19) of the oxygen-enriched bottom fraction is introduced into the low-pressure column (20), in which liquid oxygen and gaseous nitrogen are produced. The pressure in preliminary separation column (10) is essentially equal to the pressure of low-pressure column (20). The reflux for the columns can be obtained by one or two cyclic processes operated with overhead gas (11, 23) from one or two columns (10, 20). |
