Abstract

Colonne de distillation destinée à opérer à une température inférieure à la température ambiante constituée par une enceinte métallique (C) contenant des éléments adaptés à favoriser un échange de masse et de chaleur, substantiellement tout l'extérieur de l'enceinte étant revêtu d'au moins une couche de matériau isolant (I) qui juxtapose la surface extérieure de l'enceinte, la couche ou la surface extérieure de la couche en contact avec l'ambiant étant hydrofuge, voire imperméable.Distillation column intended to operate at a temperature below room temperature constituted by a metal enclosure (C) containing elements adapted to promote an exchange of mass and heat, substantially all the outside of the enclosure being coated with at least one layer of insulating material (I) which juxtaposes the outer surface of the enclosure, the layer or the outer surface of the layer in contact with the ambient being water-repellent, or even impermeable.
