The Clean Air Group, LLC Packed Tower Gas Absorber utilizes a vertical counter-current design for highly efficient absorption of a variety of toxic gases. In addition to its extensive uses in air pollution control, the Packed Tower can serve as a gas/liquid contactor in a number of process applications. Efficiencies of 99.9% and greater are not unusual for many scrubbing applications. During operation, gas flows upward through a packed bed while scrubbing liquid flows down (by gravity) over the packing material. The counter-flow design principle offers optimal mass transfer. The Clean Air Group, LLC supplies cross flow and co-current flow Packed Tower designs as well.
