Summary:High purity hydrogen is produced by a steam reforming hydrogen production unit with at least one of a bayonet reactor for reforming steam and a hydrocarbon, a recuperative burner, and a regenerative burner such that the steam reforming unit produces little or no steam in excess of the steam reforming process requirements. High purity hydrogen is separated from the syngas exiting the reformer via a pressure swing adsorption unit and combined with high purity nitrogen from an air separation unit as feedstock to a Haber process ammonia synthesis unit. Compressors for the ammonia synthesis unit are driven by higher efficiency drivers than are possible using the low temperature steam conventionally exported from a steam reforming unit. Compression power requirements are reduced.
