NOVELTY - Carbon monoxide and hydrogen are separated from gaseous mixture by feeding a first stream of first carbon monoxide-rich liquid to hydrogen stripping column at operating pressure below the feed pressure. The carbon monoxide-rich vapor is compressed, cooled, and at least partially condensed.    USE - For separating carbon monoxide and hydrogen from gaseous mixture.    ADVANTAGE - The inventive process reduces the compression power requirement, thus reducing the overall operating and capital costs of separation plant to run a process.    DETAILED DESCRIPTION - Separation of carbon monoxide and hydrogen from gaseous mixture comprises cooling and at least partially condensing feed gas (1) by heat exchange, and separating the cooled and at least partially condensed feed gas to produce the first hydrogen-rich vapor and first carbon monoxide-rich liquid. The feed gas comprises carbon monoxide and hydrogen. A first stream (12) of first carbon monoxide rich-liquid is feed to a hydrogen stripping column (13) at operating pressure below the feed pressure, such that the hydrogen is at least partially stripped from carbon monoxide-rich liquid to produce hydrogen-stripped carbon monoxide liquid (14) and hydrogen-enriched carbon monoxide vapor (22). A second stream (28) of first carbon monoxide-rich liquid is vaporized to provide a refrigeration duty required to cool and partially condense the feed gas by heat exchange and produce a carbon monoxide vapor. The carbon monoxide-rich vapor which is compressed at pressure below the feed pressure, is cooled and at least partially condensed to produce the condensed monoxide-rich vapor (31), and at least a portion to be recycled to the hydrogen column. An INDEPENDENT CLAIM is also included for an apparatus for separating the carbon monoxide and hydrogen from a gaseous mixture comprising first heat exchangers (2, 3, 6) for cooling and partially condensing feed gas, separator (8) to produce a first hydrogen-rich vapor and first carbon monoxide-rich liquid, feed gas carrying conduit, hydrogen stripping column, first stream carrying conduit, second heat exchanger for vaporizing carbon monoxide-rich liquid, second stream carrying conduit, compressor, and carbon monoxide-rich vapor carrying conduit. The apparatus further comprises third heat exchanger for cooling and partially condensing the compressed carbon monoxide-rich vapor, compressed carbon monoxide-rich vapor carrying conduit, and condensed carbon monoxide-rich vapor carrying conduit.
