REACTIVE CRYSTALLIZATION OF CALCIUM CARBONATE BY LIQUID-LIQUID REACTION

[摘要] References(7)Cited-By(8)Crystallization experiments with calcium carbonate by three liquid-liquid reaction systems from a MSMPR crystallizer were conducted to make clear the characteristics of reactive crystallization kinetics. As it was confirmed that the crystal growth obeys the ΔL law from the CSD obtained, the nucleation rate and growth rate were obtained. The effects of the operating factors and the reaction systems on the crystallization kinetics were studied. It was clarified that the nucleation rate and the growth rate are correlated by the power law model, and that the kinetic orders in the power law model are correlated with carbonate alkah''nity irrespective of reaction system.
