| abstract | (57) [Summary] (Correction) [PROBLEMS] To provide a method and an apparatus for separating air in high yield. SOLUTION: The compressed air stream is purified by a device 4 by removing carbon dioxide and water vapor. The air is passed through the heat exchanger 6 and cooled to a temperature suitable for rectification. In the high pressure rectification column 12, the air is separated into oxygen-enriched liquid and nitrogen vapor. When the oxygen-enriched liquid stream is reduced in pressure and introduced into the phase separator 42 with the reboiler 22, further separation occurs, producing more oxygen-enriched liquid and intermediate vapors. Further, the oxygen rich liquid stream is separated into oxygen and nitrogen in the low pressure rectification column 34. The intermediate vapor stream is condensed in the condenser 34 and introduced into the low pressure rectification column 34. The nitrogen vapor separated in the rectification column 12 is condensed by indirect heat exchange with the liquid from the intermediate mass transfer region of the rectification column 34 to produce a part of the liquid nitrogen reflux liquid for the rectification bodies 12 and 34. Let The impure oxygen product of rectification column 34 is evaporated by indirect heat exchange with nitrogen vapor withdrawn from rectification column 34 in condenser / reboiler 72 to produce another portion of the liquid nitrogen reflux.
