Tedder, D W

A method of recovering by distillation the separate components of a hydrocarbon gas mixture comprising ethylene, ethane, propylene and propane which comprises separating the ethylene and ethane as an overhead from a propylene and propane bottom in a first distillation tower at from about 400 to about 600 psia, separating ethylene and ethane as an ethylene overhead and an ethane bottom in a second distillation tower at from about 600 to about 700 psia, and separating propylene as an overhead from a propane bottom in a third distillation tower at from about 280 to about 300 psia is disclosed.
