Abstract: A process for producing an ammonia synthesis gas, said process comprising the steps of: —Reforming a hydrocarbon feed in a reforming step thereby obtaining a synthesis gas comprising CH4, CO, CO2, H2 and H2O, —Shifting the synthesis gas in one in or more shift steps in series, —Optionally wash the synthesis gas leaving the shift section with water, —Sending the process condensate originating from cooling and washing the synthesis gas leaving the shift section to a process condensate stripper wherein the dissolved shift byproducts and dissolved gases are stripped out of the process condensate using steam resulting in a steam stream containing more than 99% of the dissolved methanol in process condensate. —Adding all or part of said steam stream from the process condensate stripper to the synthesis gas downstream the reforming step, prior to the last shift step, wherein —The steam/carbon ratio in the reforming step and the shift step is less than 2.6.
