ABSTRACT:
An apparatus for collecting and redistributing a flow of a liquid descending in an exchange column containing a layer of structured packing and having a longitudinal axis, a cross-sectional area, and an inner wall having an inner perimeter, includes: a wall-flow collector located above the layer of structured packing, the wall-flow collector having an outer perimeter adjacent the inner perimeter of the inner wall and being adapted to collect at least a portion of the liquid descending on or near the inner wall of the exchange column; a transmission means for transmitting at least a portion of the collected liquid collected by the wall-flow collector toward the longitudinal axis a substantial distance across the cross-sectional area of the exchange column; and a dispensing means for dispensing at least a portion of the portion of the collected liquid from the transmission means to the layer of structured packing.
