A mass contactor apparatus is provided which includes an annular-shaped enclosure having an inlet for introducing gas thereinto. An entrainer deflects air flowing into the inlet into a hollow interior region of the entrainer, thereby creating a vortical flow of gas within that hollow interior region. An annular outlet enables the vortical gas flow to move upwardly and out of a central region of the entrainer. A deentrainer is positioned directly upon the entrainer for deflecting vortical flow, entering into an inlet of the central region surrounding the outlet, radially-outwardly through spaces provided between vertically-aligned, curved deflection plates in the de-entrainer to create an upward, outward circular flow along an interior surface of the enclosure. A liquid source delivers liquid to the hollow interior region of the entrainer so that the vortical gas flow draws the liquid into intimate contact therewith. This causes the liquid to be accelerated and broken up into a cloud of droplets which approach a velocity of, and move in a direction of, the vortical gas flow. A cone is positioned directly upon a top of, and covers, the de-entrainer, thereby causing droplets to move downwardly along the cone, and thereby preventing the droplets from being re-entrained with upwardly flowing scrubbed gas in a central region of the enclosure.
