The liquid liquid extraction
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 stirring device 9, allows to stir the liquid in the column, increasing the contact between the
two phases and the mass transfer from one to another.
