<p>The method involves condensing main gas in condensation passages of a main condenser (3), and feeding cool fluid to an end of evaporation passages. The fed cool fluid is evaporated, and the evaporated cool fluid and the remaining cool fluid in the end are mixed and removed from another end of the evaporation passages. High pressure nitrogen stream (5) is extracted from a single column (2) or the condenser, where the condenser is formed as a reflux condenser. The main gas column is passed into the condensation passages, which are formed as return passages. An independent claim is also included for a device for producing high pressure nitrogen by cryogenic analysis of air.</p> |
