Abstract
A fluid injection packing support with improved directional fluid flow characteristics, increased strength, rigidity and load carrying capacity includes a plurality of adjoining elongated hollow sections extending across a tower chamber and supported at opposite ends by a ledge fixed to the wall around the chamber. Each section has a spaced pair of inclined sidewalls diverging downwardly from an upper arched top wall portion to adjacent horizontal wall portions extending to adjoining short vertical wall portions. The inclined and horizontal wall portions have apertures with smoothly curved entrances and raised flange portions extending around and projecting to more sharply defined exit ends of the apertures which not only strengthens the wall and section but provides low resistance to the entrance and flow of the counter flowing fluids in one direction and greater resistance to the entrance and flow of the counter flowing fluids from the opposite exit ends of the apertures. Thus, the greatest part of the upwardly and downwardly moving fluids pass through separate apertures with little resistance which reduces the pressure drop across the packing support.
