ABSTRACT:
A relatively large volume horizontal liquid separation chamber is provided as an intermediate part of the downcomers used to transfer the denser liquid phase between contiguous trays of a countercurrent liquid-liquid extraction column. The downcomers also include two smaller vertical conduits which carry the liquid into and out of the opposing ends of the chamber. The downward flowing denser liquid phase is thereby subjected to a separation step within the downcomers to produce a stream of the less dense liquid released above the upper tray.
