Abstract
This vapor-liquid contact apparatus, suitable for use in fractionating tower sections, includes a plurality of grids which are arranged in a vertical stack. Each grid is formed of a plurality of parallel, horizontal elongated segments; and, the longitudinal axes of the segments are angularly turned relative to the segment axes in the grid therebeneath. Each segment has an upstanding flange which supports a downflowing film of liquid, and a trough portion for receiving liquid which has flowed from the flange. The trough portion is provided with liquid drain openings which are located to release liquid directly onto contacting upper edges of the flanges of the next lower grid. A plurality of connector portions, integral with and bent outwardly from the flange portions, are spot welded to the trough portions to interconnect these elements. The gas flows upwardly through openings which are provided between the flanges and troughs of the segments. The ascending gas strikes a blunt nose formed by the lower surface of the trough, giving the gas a slight angular velocity without a substantial pressure drop, and promoting the contact of the gas with the liquid film on the flange.
