Abstract

A plant and process for producing a hydrogen rich gas are provided, the process including the steps of: reforming a hydrocarbon feed in a reforming step thereby obtaining a synthesis gas including CH, CO, CO, Hand HO; shifting the synthesis gas in a shift configuration including a high temperature shift step; removal of COupstream hydrogen purification unit, such as a pressure swing adsorption unit (PSA), and recycling off-gas from hydrogen purification unit and mix it with natural gas upstream prereformer feed preheater, prereformer, reformer feed preheater or ATR or shift as feed for the process.
