Wet FGD Chemistry and Performance Factors

2010-4-28 · 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.

Lime Production

Lime Production. In order to purify the beet raw juice, SMBSC produces the lime, for the manufacture of the calcium hydroxide slurry (milk of lime), and the carbon dioxide gas - both needed for the carbonation process. These two chemicals are produced by calcining (burning) of limestone in vertical kilns, using foundry coke as a fuel.
