Extraction process

Liquid-liquid extraction is a fundamental material transfer operation based on the varying solubility of the

components of a mixture. It entails extracting a compound from a solution (solute dissolved in a diluent)

by selective transfer to a second liquid (solvent), non-miscible with the first and with different density.

A pneumatic pulsator, allows to pulse the liquid in the column, increasing the contact between the

two phases and the mass transfer from one to another.
