Abstract:
1. A screen assembly for collecting and distributing a process flow stream comprising: a plurality of wires spaced apart in a substantially parallel orientation and fixedly mounted to a support relative to each other and forming a screen, wherein the spaces define slots between neighboring wires for the passage of a fluid, and where the screen has a total slot open area; and a plurality of angled rods, having a generally L shaped configuration, with a first edge at one end of the L shape and a second edge at the other end of the L shape, where the first edge is affixed to the plurality of wires in a substantially perpendicular orientation relative to the wires and providing the support, and the angled rods form a partially covered channel on one side of the screen with the second edge of the angled rods spaced apart from a neighboring angled rod to form a channel gap with the sum of the gap areas forming the total channel gap area, and where the total channel gap area is greater than the total slot open area.
