Abstract

L'invention concerne un procédé de séparation entre de l'eau et un solide comprenant : - une étape (i) où de la matière humide est introduite dans une enceinte 10, à l'intérieur de laquelle est disposé une moyen de transfert 15, de sorte à permettre la circulation de ladite matière humide depuis une entrée 11 vers une sortie 13 de ladite enceinte, ladite matière humide est chauffée à l'intérieur de ladite enceinte 10 par transfert d'enthalpie depuis un fluide caloporteur, - une étape (ii) où la vapeur produite à l'étape précédente est comprimée, - une étape (iii) où la vapeur comprimée est introduite est condensée et transmet son enthalpie à un fluide caloporteur, caractérisé en ce que l'enthalpie captée par le fluide caloporteur à l'étape (iii) est utilisée pour l'étape (i) et en ce que l'étape (i) est réalisée dans une atmosphère saturée en vapeur d'eau.The invention relates to a process for separating water from a solid comprising: a step (i) in which wet material is introduced into an enclosure 10, inside which a transfer means 15 is arranged, so as to allow the circulation of said wet material from an inlet 11 to an outlet 13 of said enclosure, said wet material is heated inside said enclosure 10 by enthalpy transfer from a heat transfer fluid, - a step (ii ) where the vapor produced in the previous step is compressed, - a step (iii) where the compressed vapor is introduced is condensed and transmits its enthalpy to a heat transfer fluid, characterized in that the enthalpy captured by the heat transfer fluid at l step (iii) is used for step (i) and in that step (i) is carried out in an atmosphere saturated with water vapor.
