York Scheibel’s Extraction Column

Category:

The York Scheibel’s Column falls in the class of gravity-operated extractors with mechanical agitation. The presence of alternatively agitating and calming sections in a York Scheibel’s column yield higher extraction efficiency than the conventional packed column. In the setup a continuous counter current contact between the solvent and solute phases is made which results into extract and raffinate streams. Rotameters are used to measure the flow of solvent and solute respectively. The continuous and dispersed phase streams are metered and derived from separate containers. Each stage consists of a woven wire mesh section and a mixing section. The propeller speed can be controlled to the desired value by a controller. Total set-up is housed in a well-designed rigid structure. The structure also supports tanks, piping, Rotameter, panel and other units.
