Abstract

Procédé de désulfuration de gaz ou fumées provenant de la combustion d'un combustible contenant du soufre. L'anhydride sulfureux est éliminé des fumées chaudes par séchage par pulvérisation d'une suspension contenant du Ca(OH)2 dans les fumées. Des cendres volantes subsistent dans les fumées à traiter par le processus d'absorption par pulvérisation et la poudre produite dans ce processus et qui, en conséquence, contient les cendres volantes et du Ca(OH)2 ayant partiellement réagi est partiellement recyclée. L'opération est conduite de manière à obtenir dans les fumées, après traitement, une température se situant 8 à 40 degrés C au-dessus du point de rosée des fumées. Le procédé exploite au mieux le Ca(OH)2 employé comme absorbant et l'effet neutralisant des cendres volantes. Utilisation : désulfuration des fumées industrielles.
