An air separation system and method for producing a plurality of oxygen product streams at varying pressures and purities. The system combines a VPSA oxygen generator with a multi-stage cascade membrane unit to provide a high pressure, low purity product stream and a low pressure, high purity product stream.
Système et méthode de fractionnement de l'air pour l'obtention de divers circuits d'oxygène de pureté et sous pression variables. Le système combine un générateur d'oxygène VPSA avec unité à membrane en cascade multi-étagée, pour l'obtention, d'une part, d'un circuit haute pression et faible pureté et, d'autre part, d'un circuit basse pression et pureté élevée.
