Abstract

Procedure for the separation of ethylene from ethane from a C2 fraction, particularly by distillation, characterized in that ethylene is separated from ethane by feeding two different fractions obtained from fraction C2 to the distillation stage, by means of one or more fractionations of said fraction, said two different fractions consisting, respectively, in a first fraction in which the weight ratio between ethylene and ethane is greater than in the initial fraction, and in a second fraction in which the weight ratio between ethane and ethylene is greater than in the initial fraction.
