METHOD OF FORMING A HYDRATED LIME FOR ACID GAS REMOVAL FROM FLUE GAS

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 ha...

description 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 a nd 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.
