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.
