fgd limestone cheaper

DALSICA for Cleaner Fossil Fuel Power

• LIME at FGD / DSI is cheaper than LIMESTONE (lowest OpEx), • Higher control efficiency in DryFGD / DSI (due to 1μ-LIME reagent), • Multipollutant (SOx, HCl, HF, Hg etc.) control (due to D'Al-Si-Ca properties) • the range of other valuable benefits. Main Features of DALSICA

Wet Limestone | Carmeuse

Wet limestone systems are well established in some sectors such as the Power Generation industry. 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, mostly SO2. The pH of the slurry is a key parameter to be monitored as it drives the ...
