Abstract (en)
[origin: WO2008064762A2] The invention relates to a method for obtaining a carbon monoxide (37) and a hydrogen product (16) by cryogenically decomposing a feed gas (1) predominantly composed of hydrogen (H<SUB>2</SUB>) and carbon monoxide (CO) in a two-stage condensation process, maximum coldness for the second condensation stage being generated by mixing an H<SUB>2</SUB>-rich fraction (43) with liquid nitrogen (M-N<SUB>2</SUB>) (38, 42). The invention also relates to a device for carrying out said method. At least some (G-N<SUB>2</SUB>) (42) of the M-N<SUB>2</SUB> is produced from nitrogen (39) that is externally fed to the two-stage condensation process as a gas, by cooling, condensing, and, preferably, supercooling the same within the two-stage condensation process against process flows that are to be heated.
