Abstract
In a method for generating ammonia synthesis gas by electrolysis, comprising the steps of compressing air and feeding it to an air separation process, in which the content of nitrogen is concentrated while the content of oxygen and COis diluted, feeding a mixture of steam and the compressed and refined air into the electrolysis unit or into the first of a series of electrolysis units and passing the outlet from one electrolysis unit to the inlet of the next electrolysis unit, either together with air added after each electrolysis unit or only adding air after the last electrolysis unit, the electrolysis units are run in thermoneutral or endothermal mode and the nitrogen part of the synthesis gas is provided by burning the hydrogen produced by steam electrolysis by the refined air in or between the electrolysis units.
