A gas-liquid processing device used for contacting a gas stream with a liquid stream and consisting of spray nozzles housed in a containment vessel. The device finds application for transferring, on a continuous basis, chemical constituents from one phase to another. Constituent transfer is facilitated by passing the liquid through low pressure gas assisted spray nozzles, which generate multitudes of small liquid droplets that provide large amounts of surface area between liquid and gas phases. The spray nozzles consist of large diameter tubular elements wherein liquid feed flows, as films and/or rivulets, down the inner surface of the elements. Gravitational forces, and drag forces cause the liquid to fragment, so as to form streams of small diameter liquid droplets in contact with the gas phase. Improved gas-liquid contact times are realized because the droplets flow downward in very nearly vertical and parallel paths.
