ABSTRACT:
A liquid-liquid extraction device and method for operating the same is disclosed. The device includes first and second conduits in flow communication with each other via a common wall having a large number of perforations. The second conduit includes an outer tube wall having a plurality of perforations leading to the outside of the device. When liquid in the first conduit is subjected to a pressure higher than that of the second conduit, and the pressure of the liquid in the second conduit is higher than that of the ambient pressure, liquid will be allowed to flow from the first conduit via perforations in the common wall into the second conduit so as to intermingle with the liquid in the second conduit. The resultant mixture in the second conduit is then ejected to the outside as a fine liquid jet via the perforations in the outer tube wall. The first and second conduits are constructed of a liquid-tight, elastically resilient material being non-swelling in contact with organic extraction solvents.
