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
