Packed Bed Scrubbers

Packed bed scrubbers are air pollution control devices that remove contaminants from gas streams by passing the gas through a bed of packing material, where it interacts with a scrubbing liquid. The scrubbing liquid absorbs or neutralizes pollutants, cleaning the gas before it is released.


Key Features:

  • Packed Bed: The packing material (often plastic or ceramic) provides a large surface area for contact between the gas and liquid, enhancing the scrubbing process.

  • Gas‐Liquid Interaction: The gas flows upward or downward through the packed bed, while the liquid flows over the packing material, absorbing or reacting with pollutants like gases, vapors, or particulate matter.

  • Efficient Removal: Packed bed scrubbers are effective for removing soluble gases (e.g., sulfur dioxide, ammonia) and particulates from industrial exhaust streams.

  • Applications: Used in industries like chemical processing, manufacturing, and power plants to control emissions and air pollution.


Packed bed scrubbers are highly efficient at removing contaminants, making them ideal for cleaning industrial gases in various processes.
