Integration of ammonia fuel for SMR for hydrogen production

A method of producing hydrogen from a hydrocarbon feedstock, comprising:

• introducing a hydrocarbon containing feedstock stream and a steam stream into a feed pre-heater, thereby producing a heated process stream,
• introducing the heated process stream to a tube side and a fuel stream into a fired side of a steam methane reformer thereby producing a raw syngas stream,
• introducing the raw syngas stream into a water-gas shift reactor, thereby producing a shifted syngas stream,
• introducing the shifted syngas stream into a pressure swing adsorption unit, thereby producing a hydrogen product stream and a PSA tail-gas stream,
• introducing the PSA tail-gas stream into a hydrogen recovery unit, thereby producing a hydrogen-rich stream and a hydrogen-lean stream,
• wherein, at least a portion of the fuel stream comprises a superheated ammonia stream,
• wherein, at least:
• a first portion of the hydrogen-rich stream is combined with the shifted syngas stream prior to introduction into the pressure swing adsorber,
• a second portion of the hydrogen-rich stream is combined with the fuel stream prior to introduction into the steam methane reformer, and/or
• a third portion of the hydrogen-rich stream is combined with the hydrocarbon containing feedstock stream and the steam stream prior to introduction into the feed pre-heater.
