Wet Lime | Carmeuse

Wet lime systems are well established in some industries such as Power Generation & Waste to Energy. This process is based on the large degree of contact between the circulating slurry and the flue gases. This slurry circulates in the absorber tower (or scrubber) to neutralize the condensed flue gas pollutant. The pH of the slurry is a key parameter to be monitored as it drives the entire system.
