Application:

Industrial field: In the industrial field, sulfur dioxide is mainly used to produce chemicals such as sulfuric acid and sulfites. These products are widely used in industries such as fertilizers, textiles, papermaking, and petroleum. In addition, sulfur dioxide can also be used to produce pesticides, rubber products, etc.
Environmental field: In the environmental field, sulfur dioxide is mainly used to treat waste gas and flue gas. Sulfur dioxide is one of the main sources of acid rain, so it needs to be treated. By adding alkaline substances to waste gas and flue gas, sulfur dioxide can be neutralized and its harm to the environment can be reduced. In addition, sulfur dioxide can also be used for disinfection and sterilization, such as water treatment in swimming pools and water plants.
Energy field: In the energy field, sulfur dioxide is mainly used for desulfurization treatment in power plants. Coal-fired power plants are one of the main sources of sulfur dioxide emissions. By adding desulfurizers, sulfur dioxide emissions can be reduced and air quality can be improved.
