Introduction and equipment types. The separation of the components of a liquid mixture by treatment with a solvent in which one or more of the desired components is preferentially soluble is known as liquidliquid extraction. There is a net transfer of one or more species from one liquid into another liquid phase generally from aqueous to organic. Liquid liquid extraction also called solvent extraction was initially utilized in the petroleum industry beginning in the 1930 s.

1 liquid liquid extraction. 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. Todd idaho national laboratory. Law and terry a.

The equilibrium data for a liquid liquid system are of vital importance in the selection and design of an extraction equipment. It has since been utilized in numerous applications including. Liquid liquid extraction lle also known as solvent extraction and partitioning is a method to separate compounds or metal complexes based on their relative solubilities in two different immiscible liquids usually water polar and an organic solvent non polar. Extraction is a process where one or more solute s are removed from one liquid phase technically called a diluent by transferring that those the solute s to another liquid phase or a solvent since this is the operation between the two liquid phases no vaporisation is needed.
