Lime / Limestone Wet Scrubbing System for Flue Gas ...

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 12.5 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.

Scrubber - Wikipedia

Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. The first air scrubber was designed to remove carbon dioxide from the air of an early submarine, the Ictineo I, a role for which they continue to be used today.
