Biofuels and chemicals produced by biological processes such as fermentation and algae often require liquid-liquid extraction (LLE) as the first step in recovery and purification. Many of these chemicals are higher boiling than water or form azeotropes, resulting in high energy requirement for distillation.

Liquid-Liquid Extraction - an overview | ScienceDirect Topics

Liquid-liquid extraction, also known as partitioning, is a separation process consisting of the transfer of a solute from one solvent to another, the two solvents being immiscible or partially miscible with each other. Frequently, one of the solvents is water or an aqueous mixture and the other is a nonpolar organic liquid.
