The Influence of Metakaolin on Limestone .

Abstract. Recent studies have demonstrated that in the presence of limestone (CaCO 3), carbonate-AFm phases (i.e., hemi- and/or mono-carboaluminate) may be stabilized at the expense of sulfate-AFm, which is more commonly found in cement systems.This suggests that enhancing AFm phase formation may be a novel way of incorporating increased quantities of limestone as a reactive component in ...

Abstract. Reactivity of various calcium carbonate samples for flue gas desulfurization was tested. Two groups of CaCO 3 samples were considered; natural limestone containing calcite phase dominantly and samples prepared by the conversion of gypsum with ammonium and carbon dioxide (precipitated CaCO 3) containing different amounts of calcite, aragonite and vaterite.

A constant portion is removed from the partly consumed suspension of limestone circulating in the scrubber (absorber 5) of a flue gas desulphurisation plant, this portion is mixed with acid and the rate of dissolution of the suspended limestone powder is measured at a constant pH of 3.5. This measure serves to regulate the addition of fresh limestone powder to the scrubber suspension.

The limestone collected from the Ji county of Tianjin was investigated in this study. The characterization of the limestone dissolution in wet FGD system is carried out by sulfuric acid titration. The results indicate that A lower PH value is benefit for the limestone dissolution, which causes high dissolution rate within short time. Smaller particle size results in higher dissolution rate.
