A hydrated lime, especially suited for removal of acid gases, such as SO3, from flue gases, is produced by the method of hydrating quicklime while controlling the temperature increase of the reaction, caused by the hydration reaction of the quicklime with water, sufficient to form a hydrated lime having a high pore volume of between about 0.1 to 0.25 cm3/g and a specific surface area of between about 20 to 50 m2/g, and then drying the resultant hydrated lime by indirect heating to provide a residual water content of less than 2.0 weight percent of the hydrated lime product.
Une chaux hydratée, convenant spécialement à l'élimination de gaz acides, comme SO3, de gaz de cheminée, est produite par la méthode d'hydratation de la chaux vive tout en contrôlant l'augmentation de température due à l'hydratation de la chaux vive avec de l'eau. Cette méthode est suffisante pour former de la chaux hydratée ayant un volume de pores élevé, situé entre environ 0,1 et 0,25 cm3/g, et une surface spécifique d'environ 20 à 50 m2/g. La chaux hydratée obtenue est ensuite desséchée par chauffage indirect afin d'obtenir une teneur en eau résiduelle inférieure à 2,0 pour cent en poids de chaux hydratée.
