ABSTRACT:
A random dumped bed is formed of packing elements each comprising a curved base and hoops which are curved oppositely to the base. The base has a liquid channel in its concave inner surface, and openings are formed in the channel to permit liquid to flow from the channel onto the convex outer surface of the base. Two hoops project unequal distances from the base to deter axial nesting of the elements and to deter preferential orientation of the elements when they are dumped in the bed. The base has elongated slots, and nesting of the hoops in these slots is avoided by providing each hoop with nonlinear side edges and a tapered shape so that its maximum width is greater than the minimum width of a slot.
