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