Limestone Dissolution in Converter Slag: Kinetics and Influence of Decomposition Reaction

Kinetics of the Reaction of SO2 with Calcined Limestone

It is generally assumed that limestone absorbs SO2 by a mechanism involving two consecutive steps, dissociation of the calcium carbonate followed by reaction of C.0 with sulfur dioxide. be important in any of the proposed pollution control processes. and especially in the dry injection process (Potter, 1968). Several investigators (Harrington, 1968, Potter, 1969) have determined the saturation ...

Kinetics of spinel formation and growth during dissolution of MgO in CaO-Al2O3-SiO2 slag

NONLINEAR KINETICS OF SPINODAL DECOMPOSITION, AND DISSOLUTION OF INHOMOGENElTIES FORMED BY SPINODAL DECOMPOSITION IN POLYMER BLENDS

Nonlinear kinetics of both spinodal decomposition at early stages, and the dissolution of homogeneities formed during spinodal decomposition,is studied. Variation of the scattering intensity during a complete cycle consisting of a step temperature change from T i in the one-phase. region to T2 in the two-phase region, a period of spinodal decomposition followed by a temperature drop from T2 bac...

Calcium Carbonate Dissolution Rate in Limestone Contactors

The project summarized here investigated some of the parameters and relationships used to predict the performance of limestone contactors. The purpose of the project was to study the effect of limestone composition, especially the dolomite [CaMg(CO 3) 2 ] and impurity content of the stone, on the kinetics of carbonate mineral dissolution and to determine the effect of temperature on the rate of...

Determination of Reaction Coefficient, Thermal Conductivity and Pore Diffusivity in Decomposition of Limestone of Different Origin

Abstract— This paper presents a method to evaluate the reaction rate coefficient, the pore diffusivity and the thermal conductivity of the lime layer in the decomposition of limestone of various origins with an analytical solution, based on the shrinking core model. Long cylindrical limestone samples with diameters greater than 20 mm were prepared and thermally decomposed in a chamber furnace ...
