of flue gases. The reaction of sulfur di-oxide with dry limestone requires a very high temperature such as that available within the actual boiler furnace. The efficiency of SO2 removal by dry lime-stone injection has been found to be low. A much higher efficiency of SO2 removal can be realized when the flue .

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.

The limestone dissolution rate for limestone-containing slurries used in wet flue gas desulfurization (WFGD) systems is enhanced by the addition of ammonium ions. The ammonium ions may be obtained by incorporating into the limestone-containing slurry gaseous or aqueous ammonia and/or a water-soluble ammonium salt, such as ammonium sulfate, ammonium chloride, or ammonium carbonate.

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
