Batch processing in multi-product plant is still primarily used in the field of pharmaceutical, fine and specialty chemical production. Due to economic reasons this kind of small-scale production processes elude due to the growing differentiation an energetic optimization. Restructuring the previous applied method of batch processing into continuous operation mode, the formation of gel particles is the main obstacle. The emerging gel particles forming a polymer coating which lead to the blocking of the used reactor. The actual reasons for the appearance of the polymer coating
within polymerization reactions in continuous operated plans are still poorly understood.

In "KoPPonA 2.0", the aim is to analyze the causes of the formation of the polymer coat. Three large-scale material systems act as a benchmark system, which are therefore transferable to similar problems within
the polymer producing industry.

In close cooperation with the project partner of Covestro Deutschland AG, the Institute of Multiphase Flows of Hamburg University of Technology should perform flow simulation using a commercial Computational
Fluid Dynamics (CFD) - program to identify phenomenological relations during the mixing of educts, to control precisely the polymerization reaction and therefore prevent the polymer coating efficiently. Furthermore, at the Institute of Multiphase Flows different laser optical measurement techniques are available in order to characterize the appearing phenomena concerning hydrodynamic and mass transfer. These experimental data are available for the validation of the numerical flow simulation.
