Solvent extraction is a simple process in which oily waste and solvent are mixed in an appropriate proportion to ensure adequate miscibility of oil in solvent, while most water and solids are rejected as unwanted impurities that may be removed by gravitational settling or centrifugation. The oil and solvent mixture can then be separated by distillation (Hu et al., 2015).

We take the water layer and extract with fresh solvent. If we are able to extract 95% of the remaining 5%, that leaves just 0.25% behind this time. That's pretty good. By the way, that term "extract" is usually used to indicate that we are removing what we want from something we did not want. We just extracted the remaining compound from the water.
