<p>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. 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 delivered directly to the mass transfer bed, thereby reducing the opportunity for the falling liquid to become entrained in a vapor stream flowing upwardly through teh mass transfer bed.</p> |
