Abstract
Dans un procédé de séparation cryogénique d'un débit d'alimentation (4) riche en méthane contenant de l'oxygène et de l'azote,on refroidit le débit d'alimentation pour produire un débit refroidi, on envoie au moins une partie du débit refroidi à une colonne de distillation (6), on soutire de la colonne de distillation un débit de cuve, le débit de cuve étant enrichi en méthane par rapport au débit d'alimentation, on soutire de la colonne de distillation un débit enrichi en oxygène par rapport au débit d'alimentation et on introduit un débit de recyclage (9) en tête de la colonne sous forme liquide pour être séparé, ce débit étant constitué par un liquide provenant de la colonne qui est enrichi en méthane par rapport au débit d'alimentation.
