Abstract

Impure oxygen containing 70 to 98% oxygen and less than 2% argon is supplied to a synthesis-gas production unit (3a) which supplies hydrogen to an ammonia-production unit (7a). The same air-separation device (1a) can supply the nitrogen (9) to the ammonia-production unit and impure oxygen (2a) to the synthesis-gas production unit.
