in the case of wet scrubbers, there are several technologies that can be used, but many use lime or limestone slurries.with both systems, ph is a parameter that
use of limestone wet scrubbing for reduction of sulfur oxide emission removal of sulfur from stack gases seems to be the most expedient approach a closed loop system utili ing lime or chalk as the reactant was.
wet scrubbers are the most widely used fgd technology for so control throughout the preferred sorbent in operating wet scrubbers is limestone followed by lime practice, air in the flue gas causes some oxidation and the final reaction product is a wet waste water treatment is required in wet scrubbing systems.
