Apparatus and method for supporting packing in mass transfer towers and subsequent liquid redistribution

摘要

A counter-current operating, gas-liquid or vapor-liquid contact tower having a plurality of randomly dumped mass and heat transfer media. The improvement comprises first means for collecting and redistributing the flow to a lower positioned mass and heat transfer media and second means for introducing gas into an upwardly positioned mass and heat transfer media. More specifically, it comprises first construction elements in the form of horizontal, elongated troughs separated by substantial widths from each other having upturned sides extending angularly outwardly, the ends of said troughs abutting a circumferential flow channel, and second construction elements directly supported by said upturned sides, said second construction elements extending upwardly of said first construction elements.
