Abstract:
Effects of organic acids on limestone dissolution rate were investigated by pH-stat method. The results show that concentration of organic acid, acidity of limestone slurry and the kind of organic acid are the main factors to increase limestone dissolution rate. Using high concentration of organic acid, the granular limestone can be used as a desulfurizing reagent. Thus, the energy of the pulverizing limestone can be reduced. Furthermore, organic acid promoting limestone dissolution mechanism is suggested.
