Abstract: A method for producing methanol includes feeding a synthesis gas stream to a methanol production assembly; feeding an off gas stream including hydrogen to the methanol production assembly; feeding a CO2 stream to the methanol production assembly; and reacting the synthesis gas stream and the CO2 stream in the methanol production assembly to produce methanol, wherein the method further includes reacting the off gas stream with the synthesis gas stream and the CO2 stream in the methanol production assembly to produce methanol, or feeding a reforming feed stream and the off gas stream including hydrogen to a reforming portion of the methanol production assembly to form the synthesis gas stream.

Abstract: A method for recovering power during gas separation, the method including separating a mixed gas stream into a hydrogen-rich stream and a secondary stream; and expanding the secondary stream after the separating or expanding the mixed gas stream prior to the separating to recover power. The method may include using a membrane to separate the mixed gas stream into the hydrogen-rich stream and the secondary stream; and expanding the secondary stream.
