   The approximation of a well mixed reactor is prevalent when it comes to the modeling of a crystallization process. Since temperature, concentration, and mass content vary due to inhomogeneous mixing, this approximation is a very loose one. The continuously operated seeded tubular crystallizer...

4. Dynamic flowsheet model development and digital design of continuous pharmaceutical manufacturing with dissolution modeling of the final product
