Agitated Liquid–Liquid Extraction Column

Liquid–liquid extraction transfers a solute (dissolved in a diluent to form the feed solution) into a solvent with which it has greater affinity; the diluent and solvent are immiscible. Learning Objectives: Influence of solution and solvent flow rates. Influence of agitation. Learn about Agitated Liquid–Liquid Extraction Column exporters for optimal educational outcomes.. Mass balance. Number of theoretical stages (McCabe & Thiele, ternary diagrams). Learn about Agitated Liquid–Liquid Extraction Column India for optimal educational outcomes.. Number of transfer units. Mass transfer coefficients. Learn about Digital Agitated Liquid–Liquid Extraction Column for optimal educational outcomes..

The light phase is introduced at the column base and rises towards the upper settler. The heavy phase, introduced at the column head, descends towards the settling zone at the base.
