ERG spray towers are used for low‑efficiency, low capital cost scrubbing of large particulates and highly soluble gaseous contaminants in industrial exhaust streams. They are particularly effective where inlet contaminants hydrolyse to form difficult‑to‑handle solids, or where higher‑efficiency scrubbing is not required for budgetary or technical reasons.
Spray towers are especially suited to duties where the gas contains coarse particulate and/or highly soluble gases, and where a simple open‑chamber wet scrubber is preferred over packed or tray towers. In these applications, spray towers are less prone to fouling because there is no packing to block, and the open geometry can accommodate solids deposition more easily than packed beds.
A spray tower consists of an open chamber within the vessel that is irrigated with a spray of scrubbing liquor. The contaminated gas passes through the chamber, contacting the scrubbing liquor droplets, and the particulates and soluble contaminants are washed from the gas stream.
ERG spray towers are provided as complete scrubbing packages with the necessary fan, ductwork, pump, pipework and controls. In some applications, the spray tower may also be combined with other ERG mass and heat transfer equipment (such as venturi scrubbers, tray towers, packed towers or V‑tex® scrubbers) to form an integrated air pollution control solution.
