This operation involves preferential solubilising of one or more soluble constituents (solutes) of a solid mixture by a liquid solvent. The unit described here is for a semi-batch operation.

Operation – Solid-Liquid Extraction:

The solid to be extracted is put inside a glass fibre bag and placed in an extraction vessel. Solvent from the reboiler is continuously evaporated, condensed and circulated through a reflux divider by means of a piping network and valves.

When desired/ steady concentration of solute is achieved in the solution the operation is discontinued. The solution is drained off and collected for further use.

After charging fresh solid in fibre bag and solvent in reboiler, the cycle can be restarted again.

Solvent Extraction units are available in vessel sizes of 10, 20, & 50L and is suitable for operation under atmospheric pressure.
