Abstract
A method for generating hydrogen and/or synthesis gas in a production facility where little or no export steam is produced. Most or all of the high pressure steam produced from the waste heat from the process is used in the steam-hydrocarbon reformer with little or no steam export. The method uses oxygen enhanced combustion which may involve oxygen lancing and/or oxygen-enrichment. Plant efficiencies using the method and prior art-type methods are compared.
