Abstract
A method of making ethylene consisting in processing an ethylene gas condensate which is passed through a de-ethanizer to separate as gases the C.sub.2 -hydrocarbons with two carbon atoms, cooling said hydrocarbons to condensate a part thereof, feeding said hydrocarbons into a separator where the condensed phase is separated and recycled to the de-ethanizer, and feeding the non-condensed fraction of said hydrocarbons into an ethylene-recovering unit with which is associated a reboiling system for heating the fluid taken from said unit prior to recycling it to the latter, and further comprising the step of exchanging heat between the hydrocarbons from the de-ethanizer and the reflux fluid from said reboiling system so as to at least partially condensate the hydrocarbons fed to said separator.
