Abstract

Un appareil de séparation d’air comprend une double colonne, des moyens (B) pour envoyer de l’air à l’unité d’épuration à une pression supérieure à la pression atmosphérique d’au plus 1 bar, une conduite pour envoyer un premier débit d’air (8), épuré dans l’unité d’épuration, à l’échangeur de chaleur à une quatrième pression supérieure à la deuxième pression d’au plus 1 bar, une conduite pour envoyer le premier débit d’air épuré refroidi dans l’échangeur de chaleur à la deuxième colonne pour s’y séparer, un surpresseur (E), l’appareil ne comprenant aucun moyen de détente du premier débit. Figure de l’abrégé : Fig. 1An air separation device comprises a double column, means (B) for sending air to the purification unit at a pressure higher than atmospheric pressure by at most 1 bar, a pipe for sending a first flow of air (8), purified in the purification unit, to the heat exchanger at a fourth pressure higher than the second pressure by at most 1 bar, a pipe for sending the first flow of air purified cooled in the heat exchanger to the second column to separate there, a booster (E), the apparatus comprising no means of expansion of the first flow.
