What is liquid-liquid extraction?

Jack D. Law and Terry A. Todd Idaho National Laboratory Liquid-liquid extraction (also called solvent extraction) was initially utilized in the petroleum industry beginning in the 1930’s. It has since been utilized in numerous applications including petroleum, hydrometallurgical, pharmaceutical, and nuclear industries.

How do you measure the success of a liquid–liquid extraction column?

Success of liquid–liquid extraction is measured through separation factors and decontamination factors. The best way to understand the success of an extraction column is through the liquid–liquid equilibrium (LLE) data set.

What is solvent extraction & partitioning?

Solvent extraction. 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).

Which equipment is used in nuclear solvent extraction?

In the nuclear industry, specific constraints, such as remote operation and maintenance must be considered, since the solutions processed are highly radioactive. There are three basic types of equipment used in industrial-scale nuclear solvent extraction processes: mixer-settlers, columns and centrifugal contactors.
