ABSTRACT:
In a non-agitated, countercurrent flow type liquid-liquid contacting tower, trays consisting of column plates and dams are installed horizontally inside the tower shell alternately in vertical direction with a suitable interval. The column plate share a part of the cross-section of the tower to provide a flow channel or channels for the liquids, and the dam extends from the end of the column plate vertically downward and has openings near the column plate. The liquid-liquid contactor has high contacting efficiency, and thus relatively small sized apparatus can have a large treatment capacity. Because the apparatus has no moving element, maintenance is easy.
