STEAM-HYDROCARBON REFORMING METHOD WITH LIMITED STEAM EXPORT

摘要

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