摘要： 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 CO.sub.2 as the oxygen-yielding agent the gaseous mixture is compressed; residual CO.sub.2 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 H.sub.2 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.

摘要： In the recovery of a pure CO fraction from a charge containing hydrogen, carbon monoxide and methane from which water and carbon dioxide have optionally been removed, the charge is cooled and partially condensed; and the carbon monoxide is scrubbed out with supercooled liquid methane. The resultant hydrogen is stripped out, and the recovered CO/CH.sub.4 -rich fraction is separated by rectification to obtain a pure CO fraction and a CH.sub.4 -rich fraction. The supercooled liquid methane used as the scrubbing agent contains at least 2 to 15 mol % carbon monoxide, preferably 7 to 10 mol % carbon monoxide. Also, the hydrogen stripper and methane scrubbing column can be combined in a single column.

摘要： An improvement in a process for the production of high-purity hydrogen and high-purity carbon monoxide by the separation of an extensively dry and CO.sub.2 -free H.sub.2 /CO crude gas mixture, also containing methane, by means of pressure swing adsorption and one-stage partial condensation, wherein, the H.sub.2 /CO crude gas mixture is subjected to a pressure swing adsorption process, producing a high-purity hydrogen product stream, while the CO-rich gas obtained in the regeneration during the pressure swing adsorption process is compressed, cooled, at least partially condensed, and conducted into a phase separator wherein it is separated into a gaseous H.sub.2 -rich fraction and a liquid CO-rich fraction, whereupon the gaseous H.sub.2 -rich fraction is heated and admixed to the H.sub.2 /CO crude gas mixture before the latter is fed into the pressure swing adsorption. The improvement is that at least a portion of the liquid CO-rich fraction from the phase separator is at least partially expanded, heated, and conducted into the lower region of a double distillation column having an upper and lower region, a liquid methane fraction being withdrawn from the bottom of the column, a liquid high-purity carbon monoxide product fraction being withdrawn from the lower part of the upper region of the column, and a gaseous CO-rich fraction being withdrawn from the head of the column.
