Volatile organic compounds (VOCS gases for short) are a common gas pollutant that can cause great harm to the environment, the growth of animals and plants, and human health.

Volatile organic compounds (VOCS gases for short) are a common gas pollutant that can cause great harm to the environment, the growth of animals and plants, and human health. They are mainly manifested in the following aspects: (1) Most VOCs gases have an odor and are harmful, and many of them can affect human health; (2) Under the action of light, VOCs gases are required to easily photochemically react with oxidants to produce photochemical fumes, which are harmful to human health and affect the normal growth of crops; (3) Certain halogenated hydrocarbons can cause the destruction of the hydrogen layer, such as ammonia fluorocarbons (CFCS) and ammonia complex hydrocarbons; (4) Many VOCs gases belong to flammable and explosive compounds, which have a greater impact on the production of enterprises.In recent years, with the increasing realization of environmental protection issues, VOC body treatment has become an important issue that cannot be ignored. The relevant air pollution prevention and control laws clearly require that VOCs gases generated in industrial production processes should be recycled, which urgently requires the development of both economical and effective VOCs gas recovery technology. Membrane separation technology is a new type of separation technology that has been rapidly developed in recent decades. Membrane separation technology uses membrane materials to have different options for different substances. The purpose of separating and purifying the mixture is to achieve continuous process, low energy consumption, easy coupling with other separation processes, mild operating conditions, easy amplification and no secondary pollution.

The purpose of separation and purification of the mixture, with continuous process, low energy consumption, easy coupling with other separation processes, mild operating conditions, easy amplification and no secondary pollution and other advantages.With the development of membrane technology, its application range is getting wider and wider, and it shows great advantages in pollution control and material separation. Membrane technology is considered to be a feasible way to solve the current increasingly severe volatile organic compounds (VOCs gas) emissions.
