A Liquid- Liquid Extraction Column operates as a continuous extractor using a counter-current flow, where a liquid feed is continuously contacted with an immiscible solvent that selectively absorbs the desired components.
This process yields an extract containing a high concentration of the desired component at the outlet, while the raffinate or spent feed retains only minimal traces of the target component. The LLE column, equipped with a series of mixers and settlers, enhances separation efficiency and ensures optimal extraction performance.
