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.

Miniplants and Pilot Columns

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.

Kühni Agitated Columns (ECR)

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 the special mixing turbines and the perforated partition plates.

Packed Extraction Columns (ECP)

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.

Mixer-Settler and Mixer-Settler-Column

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. Our mixer-settler-column allows you to take advantage of this stage-wise contact while keeping the small footprint of a column ...
