Packed tower scrubbers (also referred to as packed bed or packed column scrubbers) are designed for chemical scrubbing of contaminants from gas streams. Internal packing in the scrubber housing provides a large wetted surface area to induce intimate contact between the contaminated gas and the scrubbing liquid. The contaminant is then absorbed into or reacted with the scrubbing liquid. Recirculation of the scrubbing liquid, which may contain caustic or acid scrubbing agents, is often required to achieve the desired outlet emissions.
Sly’s custom-designed and fabricated packed tower scrubbers are engineered for select applications for optimum tower diameter, packing depth, recirculation flow rate, and the appropriate mist eliminator style. Packed tower scrubbers can be designed to handle a wide range of airflows and can be constructed from a variety of materials. Packed tower systems, when designed correctly, can successfully ventilate harmful, toxic gas streams and exhaust clean air back to the atmosphere.
