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.

Study a continuous liquid-liquid extraction process

  • Determine operating conditions
  • Determination interphase level

Apply a ternary phase diagram

  • Mass balance
  • Determination of the efficiency of the column by defining the HTU and NTU
