Gas treatment refers to the processes used to remove impurities and contaminants from gases before they are released into the atmosphere or used in industrial applications. This can include the removal of pollutants such as sulfur dioxide, carbon dioxide, and volatile organic compounds to ensure compliance with environmental regulations and improve air quality. Common methods of gas treatment include absorption, where gases are dissolved in a liquid, and adsorption, where gases adhere to solid surfaces. Other techniques may involve filtration or the use of chemical reactions to neutralize harmful substances, making the gas safer for both human health and the environment.
