Liquid-liquid extraction unit and multistage liquid-liquid extraction apparatus using the same

Abstract

A liquid-liquid extraction unit (1) includes a feed compartment (3) for receiving an aqueous phase and an organic phase, mixing feeder such as a pump for mixing the aqueous and organic phases and conveying the mixture under pressure to a reaction compartment (4) where the mixture is subjected to an extractive reaction, and a resting compartment for separating the mixture back into an aqueous phase and an organic phase and from which each phase is recovered.
