The effect of reagent (lime or limestone) on the properties of gypsum from flue gas desulfurization
The properties of gypsum produced in flue-gas desulphurization (FGD) plants are dependent on the alkaline reagent used for neutralization. The effect of this reagent (lime, CaO, or limestone, CaCO3) on these properties are described along with the differences in the operating parameters of the FGD plant. Topics discussed include lime versus limestone, impurities in limestone impurities in lime, quality of the resulting gypsum, purity, residual alkalinity versus pH as well as particle size and shape. There are many reasons for selecting a particular FGD process and a particular reagent. History has shown that the utilization of limestone FGD gypsum in the manufacture of gypsum wallboards can produce a product with superior quality. The use of lime-based FGD gypsum in wallboard manufacture is more recent, and manufacturing parameters are being adjusted to accommodate its properties.
