Plate spacing liquid flow pattern

A liquid redistributor is required at the top of each packed bed. The liquid flow from a typical support plate is not sufficiendy uniform to properly irrigate the next lower packed bed. The multibeam type of packing support plate, which is widely used, tends to segregate the liquid downflow from a packed bed into a pair of parallel rows of liquid streams about 2-in. apart with a IQ-in. space between adjacent pairs. Gas-distributing support plates, likewise, do not give a sufficiendy uniform liquid irrigation pattern, because gas riser locations take precedence in the design of such a plate.
