Abstract

L'invention porte sur un système portable qui permet de produire de grandes quantités d'un gaz azote ou oxygène de grande pureté à haute pression. Selon l'invention, un système PSA, VSA, TSA ou à membrane perméable nettoie l'air en éliminant l'eau et le dioxyde de carbone, comme cela se fait normalement lors d'un cycle de distillation cryogénique, mais en élimine aussi une quantité significative d'oxygène ou d'azote, en fonction du gaz produit désiré. L'élimination de l'oxygène ou de l'azote préalablement au processus cryogénique permet d'utiliser une colonne de distillation significativement plus courte que d'ordinaire, entraînant une réduction de la taille de l'équipement qui rend ce dernier facile à transporter et à installer. On utilise en outre une pompe à liquide à haute pression pour augmenter la pression de l'azote ou de l'oxygène immédiatement avant leur admission dans l'échangeur de chaleur cryogénique où le liquide est vaporisé et le gaz entrant est refroidi.
