Abstract

La consommation dénergie globale dans un procédé de distillation cryogénique pour récupérer de lhélium à partir de gaz riches en azote comprenant de lhélium peut être réduite si lalimentation du système de colonne de distillation est au moins sensiblement condensée par échange de chaleur indirect contre un premier liquide de fond à une première pression, et un second liquide de fond à une seconde pression qui est différente de la première pression.
