Abstract

La présente invention concerne un réacteur de calcination flash (116) et un procédé d'activation thermique de minéraux dans le cadre duquel une augmentation monotone de la température des solides est obtenue par chauffage indirect desdits solides par un gaz de combustion ou une autre source de chaleur circulant à contre-courant du flux de solides entraînés. Des minéraux solides se présentant sous forme particulaire sont préchauffés au moyen du gaz d'échappement brûlant sortant du réacteur de calcination et entraînés dans une vapeur surchauffée générée en portant à ébullition et en surchauffant de l'eau grâce à la chaleur extraite du flux de produits solides brûlants. L'eau présente dans le flux de gaz filtré condense sous l'effet d'un refroidissement par air ou par eau. L'efficacité énergétique est renforcée grâce au préchauffage de l'air devant rejoindre la chambre de combustion au moyen des gaz d'échappement résultant de la combustion. Dans le cas de minéraux carbonatés, le flux de gaz s'échappant du condenseur est majoritairement constitué de dioxyde de carbone pur qui peut être comprimé en vue de son stockage afin de minimiser les émissions de dioxyde de carbone. Dans le cas de minéraux hydratés ou hydroxylés, l'installation génère de l'eau en tant que sous-produit.
