Control Streams with High Loading. They can be used in a chemical reactor, a distillation process, or a scrubber, also beds have been used to store heat in chemical plants. The producer gas flow rates in these experiments were in the range 49–56 m 3 /h of cooled gas, while the water flow rate was 370 l/h. Contaminant laden gas enters the scrubber tower near the bottom and flows upward through a bed of mass transfer media. The bed may be clogged by high concentrations of particulate matter, and due to the nature of the packing bed, the access and cleaning are more difficult when compared to other scrubber systems. Wet Packed Bed Scrubber System, Horizontal Scrubbers are used for gaseous and particulate control, by means of utilizing water, or other liquid, to remove pollutants from an exhaust stream. Manufacturer of packed bed scrubbers for municipal and industrial odor control applications. The gas flows through a second scrubber, a packed bed absorber, where the rest of the gases (and particulate matter) are collected. Packed Bed Scrubbers Vertical Packed Bed Scrubber.

They are well-suited as primary or secondary systems in conjunction with thermal oxidizers, and are used in a series where there are multiple-contaminant gas streams. Not suited if solid particles are present in the air since the fiber mats may plug Mechanical scrubbers - a mechanical driven rotor produces the fine water droplets in the air Packed bed scrubbers are not ideal for particulate matter scrubbing, they are more adept to gas scrubbing. The liquid contacts the gas, and the contact area is enhanced by the use of packing, which disperses the liquid and the gas, providing more contact area to transfer the targeted component into the liquid. The scrubber includes a random packing section where the absorption of gases occurs. Sly’s custom-fabricated packed bed scrubbers are engineered to optimize tower diameter, packing depth, recirculation flow rate and mist eliminator style. The so-called packed bed, that is often used in air scrubbers, is a hollow tube or pipe filled with a specifically designed packing material. This effectively increases the size and mass of the particles, making them easier to collect in a subsequent filter or separation process. and specified worldwide.
