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.
