Stirred Liquid-Liquid Extraction Study Unit


To determine overall mass transfer co-efficient based on continuous & dispersed phase.

To determine individual “Height of Transfer Unit” based on continuous & dispersed phase.

Utilities Required :

Compressed Air Supply at 2 Bar, 0.5 CFM

Water Supply

Floor Drain.

Required Chemicals & Laboratory Glassware


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 is housed in a well-designed rigid structure. The structure also supports tanks, piping, Rotameters, panel and other units.
