A gas and liquid contact body for use in a gas and liquid contact apparatus in which gas and liquid flow in cross-flow relationship to each other includes a plurality of corrugated sheets having opposed first and second edges which are facially opposed in substantially parallel relationship to one another to define a plurality of intersecting and intercommunicating passages allowing the passage of gas and liquid therethrough. In one embodiment, the first edges of the sheets are located generally in the same plane and define a gas inlet edge of the contact body. Alternate sheets in the body are narrower from their first to their second edges than the remainder of the sheets in the body. The second edges of these alternate sheets define an air outlet portion in the body and spaces between the wider adjacent sheets at said outlet portion. Separate undulating drift eliminator segments are formed in the remainder of the sheets which segments include first and second sections having mirror image corrugations formed therein with said second section being folded over the first section within the spaces defined by the alternate sheets to define a drift eliminator which restricts the discharge of liquid droplets from the air outlet portion of the contact body.

1. A gas and liquid contact body for use in a gas and liquid contact apparatus in which gas and liquid flow in cross-flow relationship to one another comprising a contact body having opposed edge portions and including first and second sets of corrugated sheets having corrugations formed therein disposed in a direction transversely of the horizontal plane of the contact body, the sheets of the first set being disposed alternately with the sheets of the second set with the corrugations of the first set crossing the corrugations of the second set, said body having inlet and outlet opposed edges in the direction of gas flow and said corrugations defining passageways in said body between its opposed edges, the sheets in said first set having first and second opposed edges with said first edge being located at the inlet edge of the body and the second edge located within the body, the sheets of said second set having first and second edges with said first edge being located at the inlet edge of the body, said sheets of the second set being wider edge to edge than the width of the body to define a sheet section whose width is a difference between the width of the body and the width of the second sheet, said sheet section being folded back onto the remainder of the second sheet whereby the second edge of the second sheet is juxtaposed to the second edge of the first sheet and the undulations formed therein restrict moisture droplets from leaving said contact body through said one edge thereof. 2. A gas and liquid contact apparatus as defined in claim 1 wherein said second edges of the second sheets are spaced from the adjacent edges of their associated first sheets thereby to define liquid discharge channels in said body between said second edges of said first and second sheets. 3. A gas and liquid contact apparatus as defined in claim 2 wherein the corrugations in said first sheets are inclined downwardly in the direction of gas flow and the corrugations in the second sheet are inclined upwardly. 4. A gas and liquid contact apparatus as defined in claim 3 wherein the sheet sections of the second sheets have corrugations formed therein which are inclined oppositely of the corrugations in the remainder of the sheets. 5. A gas and liquid contact apparatus as defined in claim 1 wherein said second sheets include a drift eliminator segment adjacent said second edge thereof which includes a first section and a sheet section; the corrugations in said first section and said sheet section being mirror images of each other. 6. A gas and liquid contact body for use in a gas and liquid contact apparatus in which gas and liquid flow in cross-flow relationship to one another and having air inlet and outlet portions, said body comprising a plurality of corrugated sheets having opposed first and second edges and being facially opposed in substantially parallel relationship to one another to define a plurality of intersecting and intercommunicating passages allowing the passage of gas and liquid therethrough, said first edges of said sheets being located generally in the same plane and defining a gas inlet edge of the contact body, alternate sheets in said body being narrower from their first to their second edges than the remainder of the sheets in said body, said remainder of the sheets having an integral drift eliminator formed therein comprising a first section lying generally in the plane of the second sheet and a second section connected to and folded over said first section, the corrugations in said first and second sections being mirror images of each other. 7. A gas and liquid contact body as defined in claim 6 wherein said second edges of said alternate sheets define spaces between the wider adjacent sheets at said outlet portion, of the contact body, with said second sections of said remainder of the sheets being located in said spaces. 8. A gas and liquid contact body as defined in claim 7 wherein said second sections of said remainder of the sheets have free ends spaced from and facing the second edges of said alternate sheets thereby to define liquid discharge channels in said body.
