ABSTRACT:
Hydrogen is recovered from a feed comprising methane, ethylene, hydrogen and acetylene by first cooling the feed and then scrubbing the cooled feed with a scrubbing liquid selected from the group consisting of liquid ethylene, liquid propane, liquid ethane and mixtures thereof to remove substantially all the acetylene. The scrubbed gas is then further cooled to condense the methane and ethylene leaving gaseous hydrogen as product.
