Abstract

Suivant ce procédé, après réchauffement de l'azote issu de la colonne basse pression, on le comprime à la haute pression au moyen d'un unique compresseur d'azote, et l'on fait fonctionner la colonne basse pression sous une pression de l'ordre de PN/PN, OU PN désigne la haute pression d'azote et PN le taux de compression dudit compresseur d'azote.
Application à la production simultanée d'une part d'azote à haute pureté sous une pression comprise entre 50 et 60 bars, et d'autre part d'oxygène sous bars, pour alimenter une unité de production d'ammoniac.
