What industrial waste gas is mainly treated by industrial waste gas purification?

The treatment object of industrial waste gas purification is very complex, and different industries and processes will produce different waste gas components. But generally speaking, industrial waste gas purification mainly deals with the following types of industrial waste gas:

Organic waste gas: such as volatile organic compounds (VOCs), benzene, toluene, xylene and other organic compounds. These organic waste gases usually come from chemical, printing, painting, coating, pharmaceutical and other industries.

Sulfide: such as sulfur dioxide (SO2) and hydrogen sulfide (H2S). These waste gases usually come from coal burning, coking, metallurgy, oil refining and other industries.

Nitrogen oxides: such as nitrogen oxides (nitrogen oxides) and nitric oxide (NO), usually come from automobile exhaust, electric power, steel and other industries.

Acid gas: such as hydrogen chloride (HCl) and hydrofluoric acid (HF). These waste gases usually come from chemical industry, metal smelting and other industries.

Dust and particulate matter: such as pulverized coal, cement dust and metal dust. These waste gases usually come from coal mines, building materials, metal smelting and other industries.

Different types of industrial waste gas have different treatment methods and technologies, so it is necessary to choose appropriate purification equipment and methods according to the specific conditions of waste gas components.
