Abstract
A new system in which a forward extraction part, a scrubbing part, and a backward extraction part operate together and synchronously to produce specific substances by extraction and separation in a liquid-liquid system. The aqueous phase is circulated independently only in the forward extraction part one or more times, and the organic phase is circulated from the forward extraction part through the scrubbing part and the backward extraction part to the forward extraction part again in synchronization with the liquid circulation of the aqueous phase.
