Montre comment les gaz sont extraits de l'air en phase liquide, puis séparés grâce à un processus de distillation fractionnée dans une unité de séparation de l'air (ASU) industrielle, avant d'être comprimés dans une bouteille de gaz.
Les gaz les plus typiques produits par distillation : Azote, oxygène et argon (souvent appelés "gaz de l'air" par opposition aux gaz produits à partir d'autres sources, généralement par un procédé chimique).
