Chemical scrubbing is a process used to remove pollutants from gases, particularly in industrial settings. It involves passing the gas through a liquid solution that reacts with the harmful substances, effectively capturing them. This method is commonly used to reduce emissions of sulfur dioxide and carbon dioxide from power plants and other facilities. The scrubbing solution can be made from various chemicals, depending on the specific pollutants being targeted. For example, alkaline solutions are often used to neutralize acidic gases. After the scrubbing process, the cleaned gas is released into the atmosphere, while the captured pollutants can be treated or disposed of safely.
