A fluid distribution tray that is capable of providing for the
distribution of a fluid across a surface area of a bed of contact
material contained within a vessel, wherein the fluid distribution tray
includes lost area due to a support element upon which the fluid
distribution tray is supported within the vessel, wherein the fluid
distribution tray includes a plurality of fluid flow means distributed
across the fluid distribution tray in a distribution pattern providing
for a high density distribution of fluid flow means within a compensation
area that is adjacent and near to the lost area and a low density
distribution of fluid flow means within the remaining useable area of the
fluid distribution tray. Also included is a method providing for a
uniform fluid distribution within a vessel.
