PACKED BED SCRUBBER


A packed bed scrubber utilizes a packed bed or tower filled with a packing material. The key features of a packed bed scrubber include:

  • Packed bed: The tower contains a bed of random or structured packing material such as plastic or ceramic.
  • Gas-liquid contact: The polluted gas stream passes through the packed bed in a counter-current or cross-flow arrangement. The packing material increases the surface area for contact between the gas and liquid phases.
  • Scrubbing liquid distribution: The liquid, often water or a chemical solution, is evenly distributed over the packing material using spray nozzles or distribution systems.
  • Absorption and mass transfer: Pollutants in the gas stream are absorbed into the liquid phase through mass transfer processes, where the liquid acts as a solvent for the pollutants.
  • Clean gas outlet: The cleaned gas exits the top of the packed bed, while the liquid collects at the bottom and is recirculated or treated further.

Packed bed scrubbers are effective for removing gases, such as acid gases (e.g., sulphur dioxide) and ammonia, as well as for controlling odours and certain volatile organic compounds (VOCs). They are commonly used when gas-liquid contact and mass transfer are required for effective pollutant removal.
