 Hydrodynamics supervision for further process control

Continuous process supervision is of great interest for nearly any (bio-)chemical process. In our laboratory an artificial intelligence-based optical sensor was developed to monitor a solvent extraction process. An image showing one of process is evaluated in 0.2 seconds/image. By detection of droplets and calculating their average size a fast solution for supervising the hydrodynamic behavior of the extraction process was developed.


Even overlapping droplets can be detected by the neural net. By improving the knowledge of the ongoing process further online process control can be applied.
The results were presented in a talk at the “Jahrestreffen der ProcessNet-Fachgruppen Extraktion, Phytoextrakte und Membrantechnik” in Frankfurt, May 23rd – 24th.
