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.

ATR-based hydrogen process and plant

A plant and process for producing a hydrogen rich gas are provided, said process including the steps of: steam reforming a hydrocarbon feed into a synthesis gas; shifting the synthesis gas and conducting the shifted gas to a hydrogen purification unit, subjecting CO-rich off-gas from the hydrogen purification unit to a carbon dioxide removal in a low temperature CO-removal section and recycling CO-depleted off-gas rich in hydrogen to the process. A drying unit upstream the CO-removal section is provided, under the addition of regeneration gas produced in the plant and process.

Plant and process for producing hydrogen with improved operation of a low temperature COremoval unit

A plant and process for producing a hydrogen rich gas are provided, said process comprising the steps of: reforming a hydrocarbon feed in a reforming step thereby obtaining a synthesis gas comprising CH, CO, CO, Hand HO; shifting said 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.

A reformer furnace is provided for use in converting a hydrocarbon feed into a synthesis gas stream. The reformer furnace includes at least one bayonet reformer tube located at least partly within an enclosed volume. The reformer furnace includes a first support arranged to support the second end portion of the at least one bayonet reformer tube against the second endwall of the reformer furnace.
