Control and resource recovery of industrial volatile organic compounds

Volatile organic compounds (VOCs) are primary sources of atmospheric pollution. Their huge emissions cause enormous harm to both the human health and the ecological environment. Various recovery and destruction control technologies of industrial VOCs gas, including adsorption, desorption, condensation, membrane separation, regenerative thermo oxidizer (RTO), regenerative catalytic oxidizer (RCO), biofiltration, photocatalytic oxidation and non-thermal plasma oxidation, have been reviewed. Their advantages and disadvantages, range and status of industrial applications, and future research directions were analyzed from the perspective of chemical engineering. Scientific research and industrial application of various abatement methods have got lots of impressive progresses, which have greatly improved the emission reduction of VOCs. However, there are still existing some problems in the current industrial VOCs control process, such as the dilemma between recovery methods and destruction methods, the treatment of VOCs gas with low concentration, large flow rate and small VOCs molecule, the disposal of VOCs gas mixed with organic and inorganic impurity, the low efficiency of single method to control the VOCs gas and so on. The solution should be promoted by the cooperation of engineers in environmental protection field and relative chemical technology. From the technical view, the process, technology and equipment of various control methods, especially recovery methods, should be further improved. Integration and coupling of different treatment modes could improve the treatment efficiency of VOCs gas and the economic benefits while reducing the energy consumption. The best way to reduce or block the emission of VOCs was to control at the source by optimizing the equipment or find the alternatives of VOCs. It could reduce the workload in later VOCs treatment. And the reduction in unorganized emission has great significance for human health and ecological environment.
