Reactive crystallization of calcium carbonate by gas-liquid and liquid-liquid reactions

Crystallization of calcium carbonate by gas-liquid and liquid-liquid reactions in a continuous MSMPR crystallizer was conducted over a wide range of suspension densities. The effects of operating factors and reaction mechanism on the cyrstallization kinetics were investigated. The crystallization kinetics for both reaction systems are correlated by the power law model and these correlations depend on the suspension density regions. The kinetic orders in the power law model are correlated with carbonate alkalinity irrespective of the reaction mechanism and the suspension density.
