文摘

The behavior of concentration multiplicity has been explored for the case of a reactiveprecipitation process in a continuous isothermal mixed suspension-mixed product removalcrystallizer. The process involves homogeneous chemical reaction in first-order reaction kineticsand subsequent crystallization of the product. The number of steady states in the reactiveprecipitator for various multiplicity regions is determined and exact uniqueness and multiplicitycriteria, which are only dependent on the kinetic properties and operational parameters of theprocess, are developed by use of bifurcation theory. The linear stability of these steady states isanalyzed by using the Routh criterion approach.
