Gas scrubbing is a process used to remove pollutants and harmful substances from industrial gases before they are released into the atmosphere. This technique often involves passing the gas through a liquid solution, which absorbs or reacts with the unwanted components, such as sulfur dioxide or carbon dioxide. The scrubbing solution can vary depending on the specific contaminants being targeted. Common methods include wet scrubbing, where the gas is bubbled through a liquid, and dry scrubbing, which uses solid materials to capture pollutants. This process helps improve air quality and comply with environmental regulations.
