Liquid-liquid extraction with recovery

DESCRIPTION

Process of separating the components of a liquid mixture based on differences in their solubility in a specific solvent.

This unit is designed for liquid-liquid extraction, a process commonly used in industry. It can also be used to determine the feasibility of a process.

The extraction column is coupled with a rectification column in order to recycle or recover the solvent.

A user manual is provided.
