| titleOfInvention | Nitrogen production method and apparatus |
| abstract | Method and apparatus for distilling nitrogen from a gaseous mixture (10) containing nitrogen and oxygen. Oxygen-enriched bottoms liquid (30) is partially vaporized within a first heat exchanger (36) to condense part of the column overhead (62) to produce reflux (29). Thereafter, the partially vaporized oxygen- enriched liquid (35) is phase separated (40). A second oxygen-enriched liquid stream composed of at least part of the liquid phase is used to substantially condense all (52) or part of the vapor stream derived from said phase separation, thereby to form a nitrogen-rich liquid stream (54). At least part of the nitrogen-rich liquid stream is reintroduced into the column (14) to increase nitrogen recovery. The second oxygen- enriched liquid stream is then used to condense a second part (64) of the reflux (26) for the column. |
