Abstract

Dans un appareil de séparation ne produisant pas de produits ultra-purs, au moins une colonne de distillation ayant un diamètre d'au moins 4m et/ou conçue pour opérer à une pression au-dessus de 4,5 bar est en acier inoxydable ou en acier contenant 9 à 10 % par poids de nickel. L'appareil de séparation peut être un appareil de séparation d'air.
