Abstract (en)
In this method, a single distillation column (9) fitted with a nitrogen refrigeration cycle is used. Liquid oxygen and/or liquid nitrogen coming from the tank of the column are pumped (14, 15) to a high production pressure and are vaporised by condensation of supercompressed air. Simultaneously, liquid oxygen and/or liquid nitrogen are produced. The installation may include a column (10) for production of impure argon, coupled to the single column. <IMAGE>
Abstract (fr)
Dans ce procédé, on utilise une simple colonne de distillation (9) munie d'un cycle frigorifique à azote. De l'oxygène liquide et/ou de l'azote liquide, en provenance de la cuve de la colonne, sont portés par pompe (14, 15) à une haute pression de production, et sont vaporisés par condensation d'air surpressé. Simultanément, de l'oxygène liquide et/ou de l'azote liquide sont produits. L'installation peut comporter une colonne de production d'argon impur (10) couplée à la simple colonne <IMAGE>
