Liquid-liquid extraction

Liquid-liquid extraction is a technically advanced, niche separation technology. It is applied when simpler alternatives such as distillation are not able to meet your requirements. Components are extracted from your feed with the help of a solvent, without an energy demanding evaporation step.

Three mini pilot columns for testing liquid-liquid extraction — In spite of considerable progress in the research and development of liquid-liquid extraction technology, designing an industrial-scale extractor based on theoretical and empirical methods is still challenging, and therefore a systematic test method is essential for a reliable scale-up.

Internals of Kühne agitated columns (ECR) for liquid-liquid extraction — In extraction with high mass transfer and/or changing physical properties, this is the column of choice. The geometry of the agitated compartments can be adapted for changing hydrodynamic conditions. Other main features are special mixing turbines and perforated partition plates.

Liquid-liquid extraction packing — The key benefit of the packed column for liquid-liquid extraction is the high throughput, which results in small column diameters. Together with specially adapted liquid distributors, our structured packing ensures optimum performance.

Three mixer-settler devices in different sizes — Mixer-settlers operate with a purely stage-wise contact. After every mixer there is a settler. Mixer-settlers can be operated in a multistage, co- or countercurrent fashion. Take advantage of this stage-wise contact while keeping the small footprint of a column.
