ABSTRACT:
The use of lightweight, elastomeric closed-cell foam elements can be of particular advantage in countercurrent flow gas-liquid contactors in order to provide aeratable non-breakable forms of mobile contacting surfaces. In particular, the use of elastomeric, spherical form, closed-cell foam elements made from heating and post curing a blend of nitrile polymer and polyvinyl chloride can provide resilience to preclude sphere breakage and also provide for softness and flexibility to effect self-cleaning characteristics.
