| titleOfInvention | Method and apparatus for the cryogenic separation of air |
| abstract | The method and apparatus are used for the cryogenic separation of air in a nitrogen-oxygen separation distillation column system comprising a first high-pressure column (23) and a low-pressure column (25, 26) and a low-pressure column intermediate evaporator (27) and a low-pressure column Bottom evaporator (28), which are both designed as a condenser-evaporator. A first feed air stream is cooled in a main heat exchanger (20, 21). The cooled first feed air stream (22) is introduced under a first pressure in the first high-pressure column (23). In the low-pressure column intermediate evaporator (27), gaseous top nitrogen (44, 45) from the first high-pressure column (23) is condensed and a liquid intermediate fraction (75) from the low-pressure column (25, 26) evaporated. At least a part (47) of the top nitrogen (46) condensed in the low-pressure column intermediate evaporator (27) is introduced as reflux liquid onto the first high-pressure column (23). At least a portion of the intermediate fraction vaporized in the low pressure column intermediate evaporator (27) is introduced as ascending gas into the low pressure column (25, 26) (77, 79). At least a portion of the bottom liquid (66) of the low pressure column (25, 26) is vaporized in the low pressure column bottom evaporator (28) in indirect heat exchange with a condensing heating fluid (58). At least a first portion of the vapor generated in the low pressure column sump evaporator (28) is returned to the low pressure column (25, 26). A gaseous oxygen product (69) is obtained from a second part of the vapor generated in the low-pressure column bottom evaporator (28) and / or from a non-evaporated part (67) of the bottoms liquid (66) of the low-pressure column (25, 26). The first high pressure column and at least a portion of the low pressure column (25, 26) are arranged side by side. The low-pressure column is formed by at least two sections, wherein a first section (25) and a second section (26) are each arranged in a separate container containing mass transfer elements. |
