Wet scrubbers are effective in removing a variety of pollutants, primarily gases and vapors. Here are some common chemicals and types of pollutants that wet scrubbers can effectively remove:

1. Acid Gases

• Sulfur Dioxide (SO?)
• Hydrochloric Acid (HCl)
• Nitrogen Oxides (NOx)

2. Volatile Organic Compounds (VOCs)

• Benzene
• Toluene
• Xylene

3. Particulate Matter

• Fine particles that may be present with gases, depending on the application.

4. Ammonia and Amine Compounds

• Ammonia (NH?)
• Amines used in various industrial processes.

5. Odorous Compounds

• Hydrogen Sulfide (H?S)
• Mercaptans

6. Heavy Metals

• Some wet scrubbers can remove metal vapors, such as lead or mercury, depending on the scrubber design and chemistry.

Mechanism of Action

Wet scrubbers typically use a liquid (usually water or a chemical solution) to capture and neutralize these pollutants. The gas stream is brought into contact with the liquid, where the pollutants dissolve or react with the scrubbing solution, allowing for their removal from the gas phase.

Wet scrubbers are versatile and can be tailored to target specific pollutants based on the liquid used and the design of the scrubber system.
