Summary

Liquid-liquid extraction (LLE), also known as solvent extraction, is a typical ternary system in the chemical engineering field, which separates chemicals from one solution to another based on the different solubility of the solute chemical in two solvents. Multiple factors need to be considered when applying the LLE process. Determining how best to choose an extractant is usually the key to the successful design of LLE separation. The properties of the LLE system, and some important definitions, are discussed in this chapter. There are various requirements for designing and building an extractor. Extractors are expected to have the capabilities and their criteria are listed. Applications in the biorefinery industry are predominantly in lignocellulosic ethanol production. With the development of new types of extraction processes, the use of LLE in the biorefinery field will have a promising future.
