Analysis of concentration multiplicity patterns of continuous isothermal mixed suspension-mixed product removal reactive precipitators

The behavior of concentration multiplicity has been explored for the case o f a reactive precipitation process in a continuous isothermal mixed suspens ion-mixed product removal crystallizer. The process involves homogeneous ch emical reaction in first-order reaction kinetics and subsequent crystalliza tion of the product. The number of steady states in the reactive precipitat or for various multiplicity regions is determined and exact uniqueness and multiplicity criteria, which are only dependent on the kinetic properties a nd operational parameters of the process, are developed by use of bifurcati on theory. The linear stability of these steady states is analyzed by using the Routh criterion approach.
