Abstract
A liquid collection and distribution device is provided to support a bed of packing material and to collect liquid exiting the bed and redistribute it to an underlying bed of packing material with improved compositional and volumetric flow uniformity. The liquid collection and distribution device includes a liquid collector, a liquid distributor, and a lattice-type framework positioned between and supporting the liquid collector and the liquid distributor. In addition to supporting the liquid collector and liquid distributor, the framework has internal fluid passages that convey the liquid from the liquid collector to the liquid distributor while shielding the liquid from ascend vapor or gas flow.
