Extractor Design
During the pilot plant tests, the extractor separation performance is measured over a range of flow rates, solvent to feed ratios and effective heights. If the extractor selected is agitated then the agitation speed is also varied. At each flow rate, the agitation is increased until the flood point is reached. From this data, the conditions that give the optimum volumetric efficiency are determined.

Extractor ScaleupNext comes scaleup to commercial size. Any scaleup procedure must determine (1) how diameter varies with throughput and (2) how stage efficiency varies with diameter. For the agitated columns, there is an additional parameter to be determined, namely (3) how the power input varies with column size.

Finally the extractor is sized with the active zone height, together with the top and bottom settler zones and instrumentation for control of the column interface.

Extractor StaticKMPS has a wide range of extractors to choose from, both static and agitated columns. Click on the column types below for more information on each.
Recovery & Recycle of Phenol in a Polycarbonate Manufacturing ProcessIn addition to the extractor, an extremely important aspect of any extraction application is the design of the system to recover and recycle the solvent. In most cases, these additional steps are accomplished by means of distillation, and when necessary, are also studied during the pilot tests.

At KMPS, we often supply the extraction and distillation components as a complete modular system. Typical examples are illustrated on this page.

Our team of experienced engineers is available to work together with you on your next liquid-liquid extraction application, from conceptualization through start-up.
