Abstract

The method according to the invention comprises the separation of a feed stream () into a first fraction () and a second fraction () and the injection of at least part of the second fraction () into a second dynamic expansion turbine () to form a second expanded fraction (). It comprises the cooling of the second expanded fraction () through heat exchange with at least part of the first headstream () coming from a first column () and the formation of a second feed stream () of the first column () from the second cooled expanded fraction.
