Abstract
A mathematical model was proposed for the gas-liquid reactive crystallization of Ca(OH)2-H2O-CO2 system under the assumption of well-mixing condition.The model includes a physical and chemical gas-liquid absorption model,a crystallization kinetics model and a population balance model.To overcome the stiff problem of the model,the high order model method of classes and high order back differential algorithm were introduced to solve the equation set.The unknown parameters were regressed based on the previous experimental data.The results of the model showed excellent agreement with the experimental data and thus provided a better understanding of the gas-liquid reactive crystallization.关键词
