Direct desulfurization of limestones under oxy-circulating ...
We compared the direct desulfurization behavior of four different domestic limestone samples (CaO fraction 40–55%, average particle size 37.5 μm) using a thermogravimetric analyzer (TGA) for experiments conducted under oxy-circulating fluidized bed (CFB) combustion conditions (temperature 600–850 °C, CO 2 60–95%).
Valmet's flue gas desulfurization process, part of its GASCON™ family of advanced air pollution control solutions, removes sulfur from flue gas efficiently, economically and reliably. The benefits of the Valmet wet limestone FGD system include
All Ducon Flue Gas Desulfurization systems are custom designed to remove sulfur dioxide from flue gases using a variety of reagents, such as: caustic, lime, limestone, ammonia, fly ash, magnesium oxide, soda ash, sea water or double alkali.
Wet flue gas cleaning Limestone flue gas desulphurization (FGD) units are well-proven and cost-effective. ANDRITZ provides novel scrubber system (FGDplus) that maximizes SO2 and dust removal while keeping energy inputs to a minimum.
Partial flue gas desulfurization can achieve about 50 to 70 percent removal of sulfur dioxide by the injection of dry limestone just downstream of the air preheater. The resultant solids are recovered in the electrostatic precipitators along with the fly ash.
Model of the Wet Limestone Flue Gas Desulfurization ...
A detailed process model of the wet limestone flue gas desulfurization system has been presented. This model can be used to calculate indispensable parameters for estimating costs and next to minimize capital and operating costs.
