Wet FGD Chemistry and Performance Factors - WPCA

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.

Predicting Viscosity of Limestone–Water Slurry

The rheological behavior of limestone–water slurry samples was investigated for different volume concentrations, particle size distribution and slurry temperature. Experiments were conducted over a range of volumetric solids concentration (Q= 0.20 - 0.46) in shear rate range of 1-300 s-1. The slurry showed Newtonian behavior up to a volumetric solids concentration of 37.8 vol. %, …
