Major research topics:

• solvent and reactive extraction: develop and validate a design tool for extraction columns based on the drop-based simulation of the columns, where the parameters of the drop models are determined from lab experiments
• coalescence, liquid-liquid phase separation, and settlers: settler design based on single-drop modelling, where the coalescence parameters are determined from a lab-scale settling experiment
• exergetic evaluation and advanced thermodynamic modelling: exergo-economic comparison of entire process routes and individual process steps is performed, especially for bio-based substances advanced thermodynamic models are derived
