Abstract

Procédé de récupération de produits organiques et/ou inorganiques volatilisables par la vapeur d'eau et/ou solubles dans l'eau à partir de résidus fusibles ou suspensions contenant de tels produits. Il consiste à alimenter la suspension ou le résidu fondu dans une colonne à plateaux de ruissellement à une température inférieure à 250 degrés C, à extraire la suspension ou le résidu fondu avec de la vapeur d'eau et/ou un condensat d'eau, à condenser le mélange sortant au sommet de la colonne, à soustraire la masse fondue ou suspension extraite restante et la phase aqueuse descendante au fond de la colonne avec séparation ultérieure.
