Abstract
In a non-agitational, countercurrent flow type of liquid-liquid contacting tower, splitter plates with plural slits and/or holes through which light and heavy liquids flow, and baffles having the appropriate shapes and areas in order to cover the liquid flowing upward or downward, are alternately mounted horizontally inside the tower shell in vertical direction. The ratios of the opening area to the total cross-sectional area in the splitter plate are 10% to 40%, and the opening area of a baffles is larger than the aperture area of a splitter plate. The advantages of this invention are as follows: Because of the high contacting efficiency, a relatively smaller contactor has an equivalent performance with that of a larger contactor; there exists no risk of plugging due to scum accumulation, and maintenance is easy.
