Abstract

Dans un procédé d'enrichissement d'un flux gazeux pressurisé (1) en l'un de ses constituants A, on sépare le flux en au moins une première et une deuxième fractions (2, 3), on envoie au moins une partie de la première fraction (2) dans une unité de séparation (ASU), l'unité de séparation fournit au moins deux débits (10, 11) dont un premier débit (10) a une teneur en constituant A supérieure à celle de la fraction (2) d'alimentation de l'unité de séparation, on mélange au moins une partie du premier débit (10) avec au moins une partie de la deuxième fraction (3) pour former un mélange gazeux pressurisé (15) et on détend la deuxième fraction (3) avant d'y mélanger au moins une partie du premier débit (10).
