Abstract
A fluid solid-contacting device eliminates the accumulation of deposits behind distribution collection conduits, reduces the differential expansion between the conduits and a containment vessel, and improves fluid distribution by extending the perforations into a back side of a distribution conduit that abuts the vessel. This apparatus has greatest application to scallop-shaped conduits that are commonly used in radial flow reactors. The perforations, extended into the back side of the scallop, ventilate the area between the scallop and the vessel holding the scallops.
