Abstract
A mass transfer column is provided with a liquid distributor that distributes liquid to an underlying mass transfer bed containing one or more random, grid or structured packing elements. The liquid distributor includes a plurality of elongated troughs that are spaced apart and extend across the column. A plurality of liquid discharge holes are positioned in side walls of the trough and are located in one or more preselected planes that are preferably spaced above a floor of the trough. Splash baffles are spaced outwardly from the trough side walls and include upper portions that are positioned to receive liquid exiting the troughs through the discharge holes. Lower portions of the splash baffles form a constricted discharge outlet in a plane below the trough for delivering liquid from the splash baffles to the underlying mass transfer bed. The liquid discharge holes in one of the trough side walls are offset from those in the other trough side wall to provide a more uniform distribution of liquid to the discharge outlet. The splash baffles are vertically adjustable and are intended to be supported on the upper surface of the mass transfer bed so that the discharged liquid is deliv…
