Abstract
ABSTRACT
This invention relates to dumped packing for use in gas/liquid contact apparatus. The dumped packings consist of a plurality of packing elements. Each element has a polygonal or arcuate base with a generally convex outer surface and a generally concave inner surface. One or more apertured poly-gonal or arcuate sections of sense opposite to that of the base are formed on or in the base intersecting the same at the ends of the sections at an included angle of less than 180°.
