Abstract
Dans un procédé de séparation d'air par distillation cryogénique, de l'air (1,7) est comprimé à une première pression, épuré, refroidi dans un échangeur de chaleur (17) et envoyé pour être séparé dans une double colonne (31,33), au moins une partie (9) de l'air épuré sort à un niveau intermédiaire de l'échangeur de chaleur, est surpressée dans au moins un surpresseur (13,15), ayant un taux de compression variable à une température intermédiaire de l'échangeur de chaleur, est renvoyée à l'échangeur de chaleur pour se refroidir et est envoyée au système de colonnes et si le taux de compression du surpresseur ou d'au moins un des surpresseurs ou des surpresseurs est au dessus d'un seuil, on ne soutire pas de débit d'oxygène gazeux (55) du système de colonnes et si le taux de compression du surpresseur ou d'au moins un des surpresseurs ou des surpresseurs est en dessous du seuil, un débit d'oxygène gazeux est soutiré de la colonne basse pression(33)et se réchauffe dans l'échangeur de chaleur.
