Energy production by combustion of S-containing non-renewable fuels requires huge consumption of limestone for the necessary Flue Gas Desulfurization (FGD) treatment in order to meet stringent SO2 emission limits. FGD (wet, dry or semi-dry) is an expensive, energy intensive, process due to its overall poor efficiency and to the need of using finely micronized CaCO3. Wet FGD laboratory tests with dolomite slurry have shown that up to ≈ 50% higher performance and faster SO2 uptake occur if the mineral is micronized by high energy mill, yielding mechanochemical activation of the solid. Further benefits arise from the use of dolomite which consistently contains Mg carbonate.
Author Keywords: flue gas desulfurization, mechanochemical activation, limestone or dolomite micronization, SO2 emission.

Abstract
Energy production by combustion of S-containing non-renewable fuels requires huge consumption of limestone for the necessary Flue Gas Desulfurization (FGD) treatment in order to meet stringent SO2 emission limits. FGD (wet, dry or semi-dry) is an expensive, energy intensive, process due to its overall poor efficiency and to the need of using finely micronized CaCO3. Wet FGD laboratory tests with dolomite slurry have shown that up to ≈ 50% higher performance and faster SO2 uptake occur if the mineral is micronized by high energy mill, yielding mechanochemical activation of the solid. Further benefits arise from the use of dolomite which consistently contains Mg carbonate.
