Wet Scrubber involves introducing the dirty gas stream into contact with a scrubbing liquid, typically water. The pollutants in the gas stream are absorbed or dissolved into the liquid, effectively removing them from the exhaust gas stream. In some cases, the liquid may also react chemically with certain pollutants to neutralize them. Wet scrubbers are effective in removing a range of pollutants, such as particulate matter, acid gases (e.g., sulfur dioxide), volatile organic compounds (VOCs), and certain toxic air pollutants. They are commonly used in industries such as power generation, metal processing, chemical manufacturing, and wastewater treatment. One advantage of wet scrubbers is their ability to handle high temperatures and moisture levels3. They can effectively capture and remove pollutants even in hot and humid environments, making them suitable for a wide range of industrial applications. Additionally, wet scrubbers can be designed to remove specific pollutants by adjusting the pH or adding specific chemicals to the scrubbing liquid. However, wet scrubbers do have some limitations. They require a continuous supply of water for operation and produce a liquid waste stream that requires proper treatment. The water consumption and wastewater treatment can add to the operational costs of the system. Additionally, while wet scrubbers are effective for removing larger particles, they may not be as efficient in capturing very fine particles.
