In the process of ethanol production and use, tail gas treatment has become an environmental issue that cannot be ignored. Ethanol tail gas usually contains water vapor, impurities and other harmful substances. If it is directly discharged without effective treatment, it will not only pollute the atmospheric environment, but also may affect human health.
