| Abstract: | The stability of isothermal mixed suspension mixed product removal (MSMPR) crystallizer with size dependent crystal growth rate was investigated by using the Routh Hurwitz criteria. The stability boundaries of the system were determined in terms of dimensionless parameters that only depended on physical properties and operational variables. Numerical solutions of the MSMPR crystallizer dynamic equations were carried out with a four order Runge Kutta technique to follow the dynamic characteristics of the crystallizer in both stable and sustained oscillatory regions. |
