摘要： In a process for recovering high-purity hydrogen and high-purity carbon monoxide by separating a largely dry and CO2-free crude H2/CO gas mixture by means of pressure-swing adsorption and single-stage partial condensation, the crude H2/CO gas mixture is subjected to a pressure-swing adsorption process, a high-purity hydrogen product stream being obtained, while the CO-rich gas arising on regeneration during the pressure-swing adsorption process is compressed, cooled, at least partially condensed and passed into a separator, in which it is separated into a gaseous H2-rich fraction and a liquid CO-rich fraction, whereupon the gaseous H2-rich fraction is heated and mixed with the crude H2/CO gas mixture before the latter is fed into the pressure-swing adsorption. At the same time, the liquid CO-rich fraction from the separator is at least partially depressurized, heated and fed to the lower region of a twin separation column, the liquid methane fraction being taken off from the bottom thereof, the liquid high-purity carbon monoxide product fraction being taken off from the middle region thereof and a gaseous CO-rich fraction being taken off from the top thereof.
