cess and plant behavior, spray layering granulation in horizontal fluidized beds is a
prototypical interconnected solids process.
The research aims of the project were:
1. Study the influence of thermal conditions on the dynamics of layer formation and
layer properties;
2. Study and characterize the influence of weir design and configuration on residence
time and particle property distributions;
3. Derive and extend population balance models to describe the temporal evolution of particle properties with respect to apparatus (weir) design and operating
parameters;
4. Using these models, study the dynamic and steady-state behavior of the continuous spray layering in horizontal fluidized beds;
5. Derive, design and implement control strategies to prevent unwanted process
behavior and guarantee required product properties under model uncertainties
and process disturbances.
This chapter is structured as follows: In Sect. 2, the basic population balance model
for continuous spray layering in horizontal fluidized beds is introduced, considering
