Abstract:
The method for recovery of olefins from feed gas containing olefins and hydrogen involves: (a) cooling and partially condensing the feed gas in a first condensing zone to yield first vapour enriched in hydrogen and a first liquid enriched in olefins, (b) introducing the first vapour into a hydrogen-olefin separation process and withdrawing a hydrogen-enriched stream and an olefin-enriched intermediate stream, (c) introducing the olefin-enriched stream into a second condensing zone where is further cooled, partially condensed and rectified in a dephlegmator and (d) withdrawing from the dephelgmator a second liquid further enriched in olefins and a second vapour depleted in olefins.
