<p>An improved process for the separation and purification of high purity acetylene and ethylene from a gaseous hydrocarbon comprised of acetylene and ethylene wherein the gaseous hydrocarbon is contacted at an elevated pressure with a selective solvent in an amount sufficient to absorb all of the acetylene and concurrent absorption of a portion of the ethylene. The enriched selective solvent is subjected at the same pressure to a stripping operation whereby a portion of the ethylene is stripped therefrom. The partially stripped enriched solvent is cooled and introduced into a second stripping zone operated at low pressure wherein the remaining ethylene is stripped therefrom and an acetylene-enriched selective solvent is obtained from which high purity acetylene is subsequently recovered.</p> |
