Abstract 837,015. Contacting fluids with liquids. BERRY, J. L. Dec. 24, 1956 [Dec. 30, 1955], No. 39213/56. Class 55 (2). Apparatus for contacting fluid and liquid phases comprises within a column a number of superimposed chambers having two open opposing vertical sides through which the chambers intercommunicate in groups through passageways formed between the chambers and the walls of the column, the number of groups of chambers corresponding to the number of individual fluid-liquid contacting paths, each of which has an inlet and an outlet for both a fluid constituting the lighter phase and a liquid constituting the denser phase, plates fixed to the inner wall of the column to extend alternately into the successive chambers of the same fluid-liquid path through one of the open sides of one of the chambers, and then into the opposite open side of the succeeding chamber, each plate forming at its fixed end a liquidcollecting trough and at its free end a liquid discharging sill, each chamber having at its base a depending wall which extends into the liquid collecting trough of the next lower chamber to form an hydraulic seal with liquid collecting in the trough when the apparatus is in use. When there are n fluid-liquid contacting paths, n being an integer equal to at least 2, the successive chambers of each contacting path are separated from each other by n - 1 chambers of the remainder of the contacting paths and each chamber is displaced from the preceding chamber by an angular displacement of #/n radians. The apparatus shown has two fluid-liquid contacting paths, chambers A 1 , B 1 , C 1 . . . constituting one path and chambers A 2 , B 2 , C 2 . . . constituting the other, the paths having a common fluid inlet and outlet and a common liquid inlet and outlet and successive chambers being displaced angularly by 90 degrees. In a modification the base and top of the chambers are dished to form additional liquid collecting troughs. Specification 755,548 is referred to.
