Dry Scrubber


  • Flow rate: The flow rate of the exhaust gas being treated can range from a few thousand cubic feet per minute (CFM) to several hundred thousand CFM.
  • Temperature range:  100 to 1,500 degrees Fahrenheit.
  • Pressure drop: The pressure drop across the dry scrubber can range from a few inches of water to several inches of water.
  • Removal efficiency: The removal efficiency of dry scrubbers can vary depending on the specific pollutant being removed and the sorbent material used. Typical removal efficiencies for dry scrubbers range from 50% to 99%.
  • Sorbent material: The sorbent material used in dry scrubbers can vary depending on the application. Common sorbent materials include activated carbon, calcium carbonate, and sodium bicarbonate.
  • Footprint: The size of the dry scrubber can vary depending on the flow rate of the exhaust gas and the specific requirements of the application. Dry scrubbers can be designed to be compact and have a small footprint, making them suitable for facilities with limited space.
  • Maintenance requirements: The maintenance requirements of dry scrubbers can vary depending on the specific design and operating conditions. Some dry scrubbers require regular replacement of the sorbent material, while others may require periodic cleaning or maintenance of the system components.


  • Dry sorbent material: The dry sorbent material used in dry scrubbers can be selected based on the specific pollutants that need to be removed. Different sorbent materials have different chemical properties and can effectively capture different types of pollutants.
  • Low water usage: Dry scrubbers require little or no water, making them a more environmentally friendly option compared to wet scrubbers, which can generate a significant amount of wastewater.
  • Lower operating costs: Dry scrubbers typically have lower operating costs than wet scrubbers because they require less maintenance and do not require as much energy to operate.
  • Compact design: Dry scrubbers can be designed to be more compact than wet scrubbers, making them a good option for facilities with limited space.
  • Can handle high-temperature exhaust gases: Dry scrubbers can handle high-temperature exhaust gases, making them suitable for use in industrial applications where high temperatures are generated.
  • Minimal environmental impact: Dry scrubbers produce little to no wastewater, which means they have a lower environmental impact than wet scrubbers.
  • Can be retrofitted onto existing equipment: Dry scrubbers can be retrofitted onto existing equipment, which can make them a cost-effective solution for reducing emissions from older industrial facilities.


Dry scrubber, also known as a dry scrubber system or a dry sorbent system, is an air pollution control device that removes pollutants from industrial exhaust gases by using a dry sorbent material. Dry scrubbers use a dry sorbent material to absorb or chemically react with the pollutants.

The dry scrubbing process typically involves passing the exhaust gases through a chamber filled with the dry sorbent material. The sorbent material can be made of various substances, such as activated carbon, calcium carbonate, or sodium bicarbonate, depending on the type of pollutants being removed.

As the exhaust gases flow through the chamber, the dry sorbent material adsorbs or reacts with the pollutants, removing them from the gas stream. The cleaned gases then exit the chamber and are released into the environment or reused in the industrial process.
