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 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

The standard grind on modern wet FGD systems is 95% passing through a 325 mesh. The components of some existing milling systems can potentially be upgraded to handle the new quantity and grinding requirements. Optimizing the grind of the limestone milling system can have a significant positive impact on limestone utilization.

Lime / Limestone Wet Scrubbing System for Flue Gas Desulfurization Background Process Instrumentation Wet scrubbers are used in utilities, paper mills, and chemical plants to remove sulfur dioxide (SO 2) and other pollutants from gas streams. Undesirable pollutants are removed by .

A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.
