Abstract
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.
