Process for the production of synthesis gas

A process for producing synthesis gas, the process comprising:

• a) reforming a hydrocarbon feed in a reforming section having a pressure inlet to obtain a synthesis gas comprising CH4, CO, CO2, H2 and H2O and impurities comprising ammonia;
• b) shifting the synthesis gas in a shift section comprising one or more shift steps in series to obtain a shifted synthesis gas;
• c) separating, from the shifted synthesis gas, a process condensate originating from cooling and optionally washing of the shifted synthesis gas;
• d) passing a part of the process condensate to a medium pressure condensate steam stripper, wherein the pressure of the medium pressure condensate steam stripper is higher than the pressure in the pressure inlet, and wherein dissolved shift byproducts comprising ammonia, methanol and amines formed during shifting of the synthesis gas are stripped out of the process condensate using steam to obtain a stripper steam stream;
• and
• e) adding the stripper steam stream to the hydrocarbon feed and/or to the synthesis gas downstream of the reforming section and upstream of the last shift step,
• wherein the remaining part of the process condensate is purged upstream of the medium pressure condensate steam stripper.
