In the fields of petrochemicals, printing, artificial leather and electronic components, baking paint, and pharmaceuticals, volatile organic compounds (VOCs) are commonly used as solvents. If these organic solvents evaporate into the atmospheric environment, they will not only cause serious pollution to the atmosphere, but also pose a threat to human health after inhaling polluted gases.
For example, benzene, as a solvent that evaporates into the atmosphere, can not only be absorbed by the human skin, but also enter the human body through the respiratory system, causing chronic or acute poisoning. Benzene compounds not only cause certain damage to the central nervous system of the human body, but may also cause neurological disorders. After entering the human body, they can also harm the blood and hematopoietic organs, and even cause bleeding symptoms or sepsis. Under oxidation, benzene can be oxidized to phenol in the body, causing abnormal liver function, which is very detrimental to bone growth and development, and inducing aplastic anemia. Therefore, ACGIH lists benzene as a potential carcinogen. Halogenated hydrocarbon compounds can cause neurological disorders, thrombocytopenia, hepatosplenomegaly, and other adverse conditions, and are highly likely to cause cancer.
So, it is necessary to control the emissions of VOCs, which is not only responsible for the environment, but also for our life and health. The current waste gas treatment technologies mainly include thermal destruction method, pressure swing adsorption separation and purification technology, adsorption method, and oxidation treatment method.
