Abstract
Procédé de séparation d'air par distillation cryogénique dans lequel on surpresse au moins une partie de l'air à distiller dans un surpresseur d'air (C2), on détend dans au moins une turbine de détente (T2, T1) de l'air comprimé et si la perte de charge entre deux points du surpresseur passe en dessous d'un seuil et/ou un débit du surpresseur passe en dessous d'un débit minimal du surpresseur, on détend une partie de l'air surpressé dans le surpresseur sans l'avoir refroidi entre le surpresseur et la détente et on envoie l'air surpressé détendu en amont ou en aval de l'au moins une turbine, sans avoir été refroidi dans l'échangeur de chaleur après avoir été surpressé.Process for separating air by cryogenic distillation in which at least part of the air to be distilled is boosted in an air booster (C2), in at least one expansion turbine (T2, T1) is expanded. compressed air and if the pressure drop between two points of the booster goes below a threshold and / or a flow rate of the booster goes below a minimum flow rate of the booster, part of the air pressure in the booster is released without having cooled it between the booster and the expansion, and the expanded air is sent upstream or downstream of the at least one turbine, without having been cooled in the heat exchanger after being supercharged.
