Working process of centrifugal extractor

Mixing and Mass transfer process

The light and heavy phase solutions entering into the internal mixing zone of the shell from the two feed inlets respectively, according to a certain ratio, so that let the two phases are rapidly mixed and dispersed, to complete the mixed and mass transfer process.

Separation process

Under the action of the feeder or turbine disc, the mixed liquor enter in bowl, in the cavity zone, it soon rotated with bowl , under the condition of centrifugal force, during the upward flow process, the heavier liquid is away from bowl center and towards to the bowl wall, while the lighter liquid is away from bowl wall and towards to the center, clarified liquids enter in collecting chamber through their respective weirs and discharged from light and heavy phase outlets, to complete the separation process.

This laboratory liquid liquid centrifugal extractor is mainly used for small experiment of laboratory. With compact structure , easy operation. It can simulate the process of multi-stage countercurrent extraction and multi-stage cross flow extraction directly, which use a small amount of aqueous feed and organic solvent.

Usually, you would have multiple centrifugal extractors in series for extraction, scrubbing and stripping(and perhaps others). The number of stages needed in each section of the process would depend on the process design requirements(necessary extraction factor).The process design is based on testing data,to get real operating data on a laboratory machine, and be able to use that data is very helpful. You have to vet your process, and know what challenges you're gonna have in your design, and what conditions to expect. So the pilot plant is absolutely the first step.
