About Flue Gas Desulfurization

Flue gas desulfurization is the removal of sulfur oxides (SO2 and SO3) from flue gas or other industrial waste gases. Flue gas desulfurization (FGD) can be divided into five methods according to the types of desulfurizers in FGD technology: calcium method based on CaCO3 (limestone), magnesium method based on MgO, sodium method based on Na2SO3, ammonia method based on NH3 and …

Wet Flue Gas Desulfurization with Lime/Limestone Slurry

In wet flue gas desulphurisation, open spray tower absorbers have prevailed which are divided into two principal zones. These are the absorption zone exposed to the flue gas and the absorber sump, in which the limestone slurry is trapped and collected. To prevent deposits in the absorber sump, the slurry is suspended by means of mixing mechanisms.
