Abstract

La présente invention concerne un procédé et un système permettant de séparer un flux de gaz d'alimentation contenant du méthane, au moins un composant en C2, au moins un composant en C3 et, éventuellement, des composants plus lourds, en un flux de gaz volatile contenant une fraction importante du méthane et d'au moins le composant en C2, et en un flux moins volatile contenant une fraction importante dudit composant en C3 et des composants les plus lourds. Le flux d'alimentation est refroidi, au moins partiellement condensé et est introduit dans une colonne de fractionnement dans laquelle le flux d'alimentation est séparé en un flux de vapeur formant le distillat de tête comprenant principalement les composants les plus légers du flux d'alimentation et en un flux liquide de fond comprenant principalement les composants les plus lourds du flux d'alimentation. L'introduction d'un rebouilleur dans la colonne de fractionnement contribue à séparer les composants co-absorbés en C2 et les plus légers des produits de fond de la colonne de fractionnement, ce qui rend plus efficace le fonctionnement d'une tour de dééthanisation aval. L'addition des résidus recyclés peut permettre de recueillir encore davantage des composants recherchés.
