Water Treatment | Carmeuse Systems
Both quicklime and hydrated lime can be converted into slurry through specialized equipment systems. Quicklime is reacted with water in a device called a "Slaker" through a process called "slaking".Slaking is an exothermic process meaning that heat is produced as the quicklime reacts with water and this heat must be managed by carefully controlling …

Enhancing the recovery of gypsum in limestone-based wet …
Commercial experience has shown that fresh slurry pH as it enters the absorber should be in the range 5.5–6.0 for limestone systems (Wang et al., 2005). As the SO 2 is absorbed from the flue gas, the slurry becomes more acidic and the pH drops. The pH of the spent slurry as it leaves the absorber is in the range 4.0–5.0 for limestone …

A lime-based system will therefore add more lime when pH drops below 12 and a limestone-based system will be controlled to around 6 pH. If lime or limestone slurry is not continually added ...

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.
