Abstract

Dans un procédé de séparation d'air par distillation cryogénique dans un système de colonnes, deux surpresseurs d'air à un seul étage (15, 25) sont reliés en série et sont couplés à deux turbines (17, 27) qui détendent de l'air n'ayant pas été surpressé. Les surpresseurs surpressent de l'air à haute pression refroidi dans une ligne d'échange où se vaporise de l'oxygène provenant du système de colonnes.
