Abstract:

In limestone gypsum wet desulphurization system the de-SOx efficiency and gypsum quality were determined by the important parameters, such as limestone slurry concentration, pH, liquid/gas ratio, Ca/S ratio, and oxidation air pressure. Through the discussions on operation manners and parameters configuration, this article tried to find the optimal operation point in order to improve de-SOx efficiency and gypsum quality.

Key words: FGD, efficiency, operation parameter, gypsum quality
