Explanation of Effect of Slurry Density on Limestone Utilization •Maintaining pH and SO 2 removal requires a specific limestone loading (g-limestone/L-slurry) level for the system. •At low density (low concentration of solids in the slurry), a higher concentration of the solids will be limestone. Therefore limestone utilization will be lower.

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

Limestone slurry is prepared mixing fine limestone powder with water in a slurry preparation tank. Sorbent slurry from this tank is then pumped into the absorber reaction tank. The absorber is a counter-flow tower with flue gas flowing upwards, while limestone slurry is sprayed downwards by an array of spray nozzles.
