12.6. TYPES OF EQUIPMENT AND DESIGN FOR LIQUID–LIQUID EXTRACTION
12.6A. Introduction and Equipment Types
As in the separation processes of absorption and distillation, the two phases in liquid–liquid extraction must be brought into intimate contact with a high degree of turbulence in order to obtain high mass-transfer rates. After this contact of the two phases, they must be separated. In both absorption and distillation, this separation is rapid and easy because of the large difference in density between the gas or vapor phase and the liquid phase. In solvent extraction, the density difference between the two phases is not large and separation is more difficult.
There are two main classes of solvent-extraction equipment, vessels in which mechanical ...
