摘要：
A sequential batch procedure for measuring the reactivity of flue gas desulfurization (FGD) limestone/lime absorbents by measuring the reaction rate with sulfuric acid is presented. It is shown that the method will predict the behavior of the absorbent in a wet FGD plant equipped with air oxidation of the bisulfite ion. With the method, sequential reactivity constants are obtained. If these constants are combined with a shrinking particle calculation, mass transfer coefficients are obtained. The reactivity constants obtained by means of the method presented can provide important information which can be used for comparing different types of absorbents with each other and for optimization of the absorbent grinding procedure.
