Schulz - Agitated Extraction Columns
As no other type, the agitated extraction column is universally suitable for practical all kind of extracting applications. Limiting condition is a minimal density difference of 0,05 kg/m3 between both phases and a not to strong tendency to form a stable emulsion, in order to allow a smooth agitation.
- Adaptation of the compartment and agitator geometry to the specific product and the operational process conditions
- The optimal droplet size can be adjusted by variation of the agitator speed
- Insensitive to solids
- Alternatively heavy or light phase dispersed
The mechanically simple construction together with the extremely small agitator speed gives:
- Minimal apparatus costs
- Minimal maintenance costs
- Minimal energy consumption
RELIABLE SCALE-UP
The safe transfer of small scale test results to larger product units is an important advantage of the agitated extraction column. The behaviour of the agitators regarding droplet dispersion and liquid fl ow follows clear and well known relationship, valid for small as well as for large scale units. Droplet size and axial mixing depending of the agitating intensity and the compartment geometry have been investigated in innumerable test runs. The result are practically applicable mathematical rules.
