Abstract
An apparatus is disclosed for distributing a downflowing liquid uniformly across the packed bed of a vapor-liquid contact column. The apparatus consists of a distributor unit and a parting manifold. The distributor unit includes a plate with upstanding walls positioned crosswise and lengthwise on the plate to define separate, open-top compartments. Installed in each compartment are a number of drip tubes which extend above and below the plate. Gas riser openings are positioned between certain compartments and the distributor unit is mounted inside the column above the packed bed. The parting manifold is mounted above the distributor unit, and it includes a header circuit, crosswise end conduits, a crosswise lateral conduit, and a vertical standpipe conduit. The end conduits and lateral conduit have closed ends and each includes outlet ports therein. The downflowing liquid enters the manifold through the standpipe conduit, drops through the outlet ports into each compartment, and flows downwardly through the drip tubes onto the packing.
