Gas/liquid contact apparatus

Apparatus for gas/liquid contact, comprising:

• (a) a plurality of packing sheets arranged in a generally parallel, vertical, upright, face-to-face relationship;
• (b) each of said packing sheets having a series of generally parallel corrugations formed therein that generally extend at an angle in the range of about 10 to 45 degrees from a vertical direction;
• (c) each of said corrugations being formed so as to define an alternating series of longitudinally extending, oppositely inclined surfaces that intersect and pass through a center plane of the packing sheet so as to define hills and valleys on opposite sides of the center plane;
• (d) wherein the amplitude relative to the center plane of said inclined surfaces at said hills is substantially equal to and opposite the amplitude of said inclined surfaces at said valleys;
• (e) wherein the relative location and the distance between the adjacent hills and valleys in adjacent corrugations varies;
• and
• (f) said packing sheets being arranged adjacent to each other such that the corrugations of adjacent packing sheets are oppositely oriented.
