Modeling Limestone Reactivity And Sizing The Dissolution ...

Limestone slurries are widely utilized in wet flue gas desulfurization (WFGD) processes. The evaluation of the reagent's reactivity is fundamental for process design and plant operation. The comparison of different limestone and dolomite rocks through dissolution experiments was realized by applying a model for second‐order kinetics.

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.

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.
