3 Results and Discussion
This section presents selected results from steady-state and dynamic experiments
and simulations. The results of the steady-state simulation are compared to the corresponding validation experiments in Sect. 3.1. Furthermore, the model is applied to
investigate the influence of recycle streams on the product PSD. Section 3.2 deals
with the results from “experimental simulation” to verify whether an equivalent circuit of PFR and well-mixed BF can be used to simulate a semi-batch STR. Section 3.3
