ABSTRACT:
The present invention is a cryogenic process for the production of nitrogen by distilling air in a double column distillation system comprising a high pressure column and a low pressure column. The critical step of the invention is the condensation of a nitrogen stream in the top most reboiler/condenser located in the stripping section of the low pressure column to provide column reboil and the total condensation of a portion of the compressed feed air in the bottom most reboiler/condenser located in the bottom of the low pressure column.
