| description | Damp sodium bicarbonate filter cake is pre-dried and calcined to produce light soda ash in a process comprising a carbon dioxide ebullated fluid bed pre-dryer working in connected series relationship with a plurality of carbon dioxide ebullated fluid bed/bag filter calcination systems such that bicarbonate decomposition during pre-drying is minimized and the thermal treatment of small particles during calcination is optimized.
On pré-déshydrate et on calcine un gâteau de filtre humide au bicarbonate de sodium pour produire des cendres volantes de carbonate de sodium au moyen d'un procédé dans lequel on utilise un pré-déshydrateur à lit fluide en ébullition au dioxyde de carbone qui fonctionne en étant couplé en série avec une pluralité de systèmes de calcination à sac de filtration/lit fluide en ébullition au dioxyde de carbone, de sorte à réduire au minimum la décomposition du bicarbonate pendant la pré-déshydratation, et à optimiser le traitement thermique des petites particules pendant la calcination. |
