使用五水硫酸铜、硫酸镍铵、硫酸钾和大豆蛋白在连续 MSMPR 结晶器中结晶的实验响应来同时测定晶体生长和成核速率以及团聚内核。所有这些系统在稳态下测量的产品晶体尺寸分布都被转换为晶体体积坐标，以使用两种方法：力矩分析和参数表征的优化程序。通过优化程序进行迭代非线性参数估计，用于从晶体体积坐标中的团聚模型的解中推导出动力学速率参数，该参数是从 Liao 和 Hulburt (1976) 的分析中扩展的，从产物晶体的翻译数据集。五水硫酸铜系统获得的动力学结果与幂律动力学表达式相关，描述了重要可观察变量的影响
Experimental responses from crystallization of copper sulfate pentahydrate, nickel ammonium sulfate, potassium sulfate, and soy protein in continuous MSMPR crystallizers were used to determine simultaneously crystal growth and nucleation rates and agglomeration kernels. Measured product crystal size distributions at steady state for all these systems were transformed into crystal volume coordinates to use two methods: moment analysis and optimization procedure for parameter characterization. An iterative nonlinear parameter estimation by optimization procedure was used to deduce the kinetic rate parameters in the solution of the agglomeration model in crystal volume coordinates, extended from the analysis by Liao and Hulburt (1976), from the translated data set for the product crystals. The kinetic results obtained for the copper sulfate pentahydrate system were correlated in terms of power law kinetic expressions depicting the effect of significant observable variables
