Control of Crystallisation Processes
From Fachgebiet Regelungssysteme TU Berlin
Abstract
In the chemical and pharmaceutical industries, crystallisation is used for the production of solids from liquids. Product quality usually depends heavily on crystal size distribution (CSD). The temporal evolution of CSDs is typically described by population balance models, i.e., partial integro-differential equations. We have investigated three distinct topics:
- Stabilisation and disturbance rejection for continuously operated crystallisers using infinite-dimensional feedback synthesis techniques.
- Trajectory planning and feedback control for batch crystallisers using flatness based methods.
- Control of preferential crystallisation processes for the seperation of enantiomers.
