For obtaining pure CO from a gaseous mixture, consisting predominantly of hydrogen and carbon monoxide, e.g., that produced by the endothermic catalytic oxidation of hydrocarbons in the presence of CO2 as the oxygen-yielding agent the gaseous mixture is compressed; residual CO2 and water are removed by adsorption; the resultant purified gaseous mixture is cooled to condense a predominant portion of CO; the condensed CO is pressure-reduced to remove dissolved H2 in the gaseous phase, the latter being recycled in gaseous form to the gaseous mixture; a fraction of the remaining liquid CO is partially vaporized and engine expanded to produce refrigeration for the system, and after engine expansion, is recycled to the gaseous mixture upstream of the compressor.

A process for obtaining purified carbon monoxide from a gaseous mixture consisting essentially of hydrogen and carbon monoxide (H2-CO), comprising compressing the H2-CO gaseous mixture; cooling the compressed gaseous mixture to condense a predominant portion of the carbon monoxide containing dissolved hydrogen; pressure reducing resultant condensed carbon monoxide to evolve dissolved H2 in the gaseous phase thereby obtaining purified liquid carbon monoxide; recycling resultant evolved H2 into said gaseous mixture; vaporizing a fraction of resultant purified carbon monoxide, engine expanding resultant vaporized fraction, and recycling resultant engine expanded fraction to said gaseous mixture, and withdrawing another fraction of said purified carbon monoxide as product.
