Unit Operations Lab: Mass Transfer and Axial Dispersion in a Reciprocating-Plate Liquid Extraction Column
A set of related experiments involving liquid-liquid extraction is described. The proposed chemical system is water/kerosene/butyric acid, which exhibits interesting phase equilibria at low butyric acid concentrations. A reciprocating-plate extraction column is used. Hydrodynamic experiments characterize flooding and axial dispersion behavior, and the mass transfer efficiency is also measured.
