In this process, after heating the nitrogen produced from the low-pressure column, it is compressed at high pressure using a stand-alone nitrogen compressor. The low-pressure column is operated at a pressure of the order of PN/PN, where PN represents the high pressure of nitrogen, and PN the compression ratio of the nitrogen compressor in question. This process can be applied in the simultaneous production of one part high-purity nitrogen under a pressure of between 50 and 60 bars, and one part oxygen, under 65 bars, to feed an ammonia production unit.
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.
