Abstract
A selected paraffinic or olefinic liquid is used to scrub acetylene from a minor gas fraction of uncondensed gas from a hydrocarbon feed mixture containing ethylene, hydrogen, acetylene and methane. Hydrogen product gas is separated and recovered from said minor gas fraction. The major gas fraction is processed without said acetylene removal operation, but under elevated pressure conditions effectively avoiding acetylene solidification during the separation and recovery of an ethylene-enriched liquid.
