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.

The solids concentration in the scrubbing loop is controlled by the use of nuclear density meters in the FGD recirculation tank. The scrubbing solution pH is maintained at a minimum value of 5.0. Control at this level prevents major pH changes in the scrubber, which may change salt saturation levels and cause solids deposition and scale ...

with the FGD residues. The fly ash in dry FGD materials has similar particle size, particle density, and morphology to those of conventional fly ashes, but FGD materials have lower bulk densities. The difference in bulk density is due to variations in the chemical and mineralogical characteristics of the reacted and unreacted sorbent. Dry
