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.
