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.
