Liquid-Liquid Extraction In A Packed Tower


The set-up consists of a glass column packed with Rasching rings. Continuous counter current contacts between the solvent and solute phases is made, which results into extract and raffinate streams. Flow meters (Rota-meters) are used to note the flow of solvent & solute respectively.

The continuous and dispersed phase streams are metered and derived from separate containers. The total set-up is housed in a well-designed rigid structure. The structure also supports tanks, piping, Rota-meters, panel and other units.
