Digitalization in the chemical industry will only be possible in the future with a better understanding of the local phenomena in chemical apparatus. If this is achieved, optimization of chemical processes is possible, and more efficient and sustainable processes can be planned or designed.
However, this requires an improvement of the current model design, especially for multiphase systems, away from one-dimensional models towards an isolated consideration of hydrodynamics, particle size as well as mass transport.
To achieve this, a complex integration of measurement techniques as well as simultaneous acquisition of the core parameters (particle size, concentration change, velocities) will be necessary, a corresponding modeling of the unknowns, as well as a mapping of single phenomena by isolated experiments. This can only be achieved by an interdisciplinary approach.
