The packed tower scrubbers are used to remove particulate and / or vapor contaminants from an exhaust gas stream by way of dilution or absorption.
A packed tower is an efficient method of carrying out mass transfer between gas and liquid phases. Packed tower scrubbers incorporate packing media
to facilitate intimate contact between a scrubbing liquid and gas to be scrubbed.
Applications are: reduction of dust or gaseous emission levels, product recovery, air pollution and odor control.
In countercurrent scrubber operation, the gas flows upward through the packing material, while the liquid flows downward by gravity through the
packing material. The liquid wets the surfaces of the packing material, providing a large amount of surface area for diffusion of one or more components of the gas stream into the liquid stream, thereby cleaning the gas. The scrubbers are available in stainless steel and GRP (Glass Reinforced Plastic).
