The present invention provides a method and apparatus for continuously treating a flowing gas with a liquid to remove unwanted materials from the gas. Packing elements are directed downwardly along a predetermined zigzag path of travel, with the packing elements being maintained in the form of a relatively thin layer. A liquid is directed onto the layer of packing elements while a flowing gas is directed upwardly along a sinuous path of travel repeatedly passing back and forth through the downwardly moving layer of packing elements successively from opposite sides thereof. The packing elements are discharged from the lower end of the path of travel while clean packing elements are directed into the upper end to replace those which are discharged. The discharged packing elements are cleaned and recycled for reuse.
