Abstract
A cyrogenic technique for recovering ethene from a gaseous mixture containing methane, ethane, etc. Operating methods and apparatus are provided for passing the gas feed through a chilling train having a series of dephlegmator-type exchange units to condense liquid rich in ethene and ethane, while separating a major portion of methane and lighter gas. A multizone demethanizer removes condensed methane from the C.sub.2 fraction to provide a pure product economically.
