Packed Bed Scrubber Designed to neutralize many gaseous pollutants, packed bed scrubber offers a compact design and low capital cost. Contaminant laden gas enters the scrubber tower near the bottom and flows upward through a bed of mass transfer media. Nederman MikroPul packed bed scrubber has been successfully utilized for combustion, reagent preparation, odor control and incineration applications. The scrubbing solution consists of water and a small amount (usually < 5%) of sulfuric acid (H 2 SO 4). Standard materials are polypropylene, fiberglass and PVC. Packed bed scrubbers contact a liquid, typically water, with a gas to transfer a component of the gas into the liquid. This is determined by the process to be handled by the scrubber, information provided by customer and Tri-Mer’s analysis. In the vertical counter-current design, gas flows upward while scrubbing liquid flows down through banks of sprays. This type of scrubber spreads the liquid over packing material in order to provide a large surface area for liquid/gas interaction. Packed tower scrubbers are suitable for chemical processes, metal finishing, semiconductor manufacturing and other industrial operations generating fumes and gases. The fluid captures the pollutant and is collected for discharge or is treated for reuse. 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. 5 for the full unit (wet packed bed scrubber+dry sand filters). Modifying the qualities of the gas and liquid, by increasing its temperature, wettability, or diffusivity improves mass transfer. A high-efficiency mist eliminator removes entrained liquids. The gas flows through a second scrubber, a packed bed absorber, where the rest of the gases (and particulate matter) are collected. 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. It is widely used in many industries in Malaysia to remove soluble gaseous pollutants. Manufacturer of packed bed scrubbers for municipal and industrial odor control applications. Increasing the volume of the mass transfer media increases the contact time of the liquid with the gas, increasing the time for the component to transfer from the gas to the liquid. Packed Tower Wet Scrubbers Packed tower scrubbers , also called packed bed or packed column scrubbers, are best for getting rid of gas phase emissions like sulfur dioxide or other odors and acids.
