Cryogenic air separation process for the production of nitrogen in a double column distillation system |
| abstract |
Cryogenic process for producing nitrogen by distilling air in a double column distillation system comprising a high pressure column and a low pressure column. The critical step in the process is the condensation of a stream of nitrogen in the upper boiler / cooler arranged in the stripping section of the low pressure column to provide column boiling and the total condensation of a part of the compressed supply air in the lower boiler / cooler arranged in the bottom of the low pressure column. . |
