Abstract (en)
[origin: JP2000203827A] PROBLEM TO BE SOLVED: To provide a new method for supplying impure oxygen to a unit for producing a synthetic gas. SOLUTION: Impure oxygen comprising 70-98% of oxygen and <2% of argon is supplied to a unit 3 for producing a synthetic gas. The unit 3 supplies hydrogen to a unit 7 for producing ammonia. An air-separating device 1 can deliver nitrogen and the impure oxygen to the unit 7 for producing the ammonia and the unit 3 for producing the synthetic gas, respectively.
Abstract (fr)
De l'oxygène impur contenant de 70 à 98% molaires d'oxygène et moins de 2% molaires d'argon est fourni à une unité de production de gaz de synthèse (3) qui fournit de l'hydrogène à une unité de production d'ammoniac (7). Le même appareil de séparation d'air (1) peut fournir l'azote (9) à l'unité de production d'ammoniac et de l'oxygène impur (2) à l'unité de production de gaz de synthèse. <IMAGE>
