a process whereby the watery phase is separated from the oily phase (in the two-phase extraction system), or whereby both the watery phase and the impurities are removed from the oily phase (in the three-phase system).

Example

next and immediately after the previous process, the "liquid-liquid separation" is carried out, in order to remove the remains of solid and aqueous liquid impurities which usually escape from the previous process, obtaining a practically finished oil, but not final, and aqueous effluent, which, depending on the extraction system, is called vegetation water, alpechin or oil wash water.
