Sloped film fill assembly

DETAILED DESCRIPTION What is claimed is: 1.
In a liquid-gas contact tower having at least one upright side wall with a gas inlet opening therein, means for supplying gravitating liquid to the upper portion of the tower, gas outlet opening, film fill means mounted in said tower having opposed upper and lower surfaces, said film fill means having a principal plane inclined at an angle of between about 20.
degree.
and 70.
degree.
to the vertical and also disposed to intersect a gas path extending between said gas inlet and outlet openings, said upper surface being disposed below said liquid supply means to intersect liquid gravitating therefrom, said lower surface being in communication with said gas inlet opening and said upper surface being in communication with said gas outlet opening, said film fill means comprising a plurality of sheets of cross-fluted corrugated fill mounted so that adjacent sheets define flow passages which allow for the passage of gas along said path and of liquid gravitating from said liquid supply means and said sheets having lower edges defining said lower surface of the film fill means, said sheets being positioned such that said passages extend at an angle to the vertical, the improvement comprising a plurality of dewatering sheets secured in the lower edges of the sheets of said film fill means at least at said lower surface thereof and extending transversely of said film fill sheets to intercept liquid collecting and flowing under the influence of gravity along the inclined lower surface of said film fill sheets adjacent said lower edges of the sheets of the film fill means and clogging said passages; said dewatering sheets causing the water flowing along said lower edges of the sheets to fall from the film fill means thereby to decrease air pressure drop through said film fill means; said dewatering sheets extending into said film fill sheets for a predetermined depth of penetration along said lower edges.
2.
In a liquid-gas contact tower as defined in claim 1, wherein said dewatering sheets are mounted to extend vertically
