Abstract

L'invention concerne un procédé d'absorption à contre-courant permettant la déshumidification de l'air humide ou de la vapeur d'eau saturée. Le liquide d'absorption utilisé consiste en une solution aqueuse d'un ou plusieurs éléments non volatils. L'absorption est effectuée adiabatiquement, c'est-à-dire sans échanges notables de chaleur avec l'environnement, et à des proportions pondérales entre le liquide d'absorption et le gaz ou la vapeur telles que la plus grande partie de la chaleur de condensation de la vapeur d'eau condensée pendant l'absorption est transférée au gaz ou à la vapeur devenant progressivement de plus en plus sec, afin d'élever sa température. Le liquide d'absorption dilué subit une concentration par évaporation pour être recyclé et réutilisé. L'air ou la vapeur déshumidifié et chauffé peut être utilisé par exemple dans un processus de séchage, par exemple de bois, de cellulose, de papier, de tourbe, etc.
