摘要
A method for the co-production of hydrogen and methanol including a hydrocarbon reforming or gasification device producing a syngas stream comprising hydrogen, carbon monoxide and carbon dioxide; introducing the syngas stream to a water gas shift reaction thereby converting at least a portion of the CO and H2O into H2 and CO2 contained in a shifted gas stream; cooling the shifted gas stream and condensing and removing the condensed fraction of H2O; then dividing the shifted syngas stream into a first stream and a second stream; introducing the first stream into a first hydrogen separation device, thereby producing a hydrogen stream, and introducing the second stream into a methanol synthesis reactor, thereby producing a crude methanol stream and a methanol synthesis off gas; introducing at least a portion of the methanol synthesis off gas into a second hydrogen separation device.
