Volatile organic compounds: Current status and control technologies
Ÿڼ*
Abstracts
Volatile organic compounds(VOCs) are harmful substances that contribute to stratospheric ozone depletion,
tropospheric photochemical ozone formation, and carcinogenic human health effects. Worldwide, there are major
concerns over the emission of VOCs. Any plans for pollution reduction and management should be established
based on database of VOC emission and characteristics. In this paper, the status of VOCs by year, region, and
industry were investigated, and then technologies for VOC emission control were introduced. The estimation of
VOC emissions by year was gradually increased, and VOC emission due to the utilization of organic solvents
was the most common form. VOCs in the atmosphere were detected at the highest concentration in industrial
complexes. In most of the industry, it was confirmed that emissions of toluene were the highest among the VOCs.
Finally, available VOCs control technologies were introduced, including thermal and catalytic oxidation,
adsorption, absorption, biological treatment, non-thermal plasma, electron beam irradiation, and photocatalyst.
