Abstract

Dans un procédé de séparation d'air, un débit d'air (2) est surpressé dans un surpresseur chaud (B), refroidi et envoyé au bout froid d'un échangeur (E1), une partie (4) de l'air est surpressée dans un surpresseur froid (C) et ensuite distillé dans une colonne de séparation d'air.In an air separation process, an air flow (2) is boosted in a hot booster (B), cooled and sent to the cold end of an exchanger (E1), part (4) of the air is overpressed in a cold booster (C) and then distilled in an air separation column.
