Abstract

L'invention concerne un procédé d'extraction d'une fraction de produit d'hélium (6) à partir d'une fraction de charge (3) contenant de l'azote et de l'hélium. La fraction de charge (3) contenant de l'azote et de l'hélium est partiellement condensée (E1), séparée en une 1ère fraction riche en hélium (5) et une 1ère fraction riche en azote (8) et la première est repurifiée par adsorption. Selon l'invention, la séparation est effectuée dans une colonne de séparation (T) à laquelle sont acheminées la 1ère fraction riche en azote (8) sous forme de reflux et un courant partiel de la 2ème fraction riche en azote sous la forme de gaz de réextraction (12). Le volume de gaz de réextraction (12) est réglé de telle sorte qu'une 3ème fraction riche en azote (20), laquelle contient au moins 30 % de l'azote contenu dans la 1ère fraction riche en azote (8), peut être extraite dans la colonne de séparation (T).
