Reagent Preparation and Dewatering in a Wet FGD System

If limestone consumption must be increased to improve SO2 removal the reagent preparation and dewatering systems may be undersized In most cases higher SO2 removal requires a finer grind than what older systems were originally designed to achieve The standard grind on modern wet FGD systems is 95 passing through a 325 mesh.

Lime / Limestone Wet Scrubbing System for Flue Gas

Neither lime nor limestone dissolves well in water and therefore both are pumped in slurry form to the scrubber tower Lime slurry is more alkaline having a pH of 12.5 while limestone slurry is roughly neutral A lime based system will therefore add more lime when pH drops below 12 and a limestone based system will be controlled around 6 Unless
