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 (Rotameters) 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
- To determine overall mass transfer co-efficient based on continuous & dispersed phase.
- To determine individual “Height of Transfer Unit” based on continuous & dispersed phase.
