Abstract: Process and system for producing an ammonia synthesis gas, the process comprises the steps of: (a) providing a separate stream comprising nitrogen by pressure swing absorption of ambient air; (b) providing a separate stream comprising hydrogen by electrolysis of water and/or steam; (c) combining the separate streams obtained in steps a) and b) into a mixed stream comprising hydrogen and nitrogen; (d) pressurizing the mixed stream from step (c); and (e) removing residual amounts of oxygen further contained in the mixed stream by catalytic hydrogenation of the oxygen with a part of the hydrogen contained in the mixed stream upstream step (d) and/or downstream step (d) and/or during step (d) to produce the ammonia synthesis gas.
