Wet Scrubbers: These systems use a liquid (usually water or a chemical solution) to absorb or react with pollutants in gas streams. They are effective in removing particulate matter, gases, and vapors and are commonly used in various industrial applications.
Dry Scrubbers: These systems utilize a dry reagent or sorbent to capture pollutants from gas streams. They are particularly effective for removing acid gases (like SO2 and HCl) and are often used in industries where water use is limited or where moisture-sensitive processes are involved.
Semi-Dry Scrubbers: These systems combine elements of both wet and dry scrubbers. They typically use a spray of a slurry or a mixture of solid sorbents to capture and neutralize pollutants, providing a balance between efficiency and operational flexibility.
Each type of scrubber is designed to address specific pollutants and operational conditions, making them suitable for various industrial applications.
