摘要:

Emissions from the chemical industry are among the important sources of atmospheric volatile organic compounds (VOCs), which face control challenges such as multiple emission sources, high emission intensity and complex pollutant types. In this study, a typical chemical enterprise is selected as the research object, and VOCs characteristics such as emission amount, concentration and composition are analyzed; end-pipe treatment of VOCs is evaluated and control suggestions are proposed. Results show that the annual emission amount of VOCs from organized stacks was 64.08 tons, accounting for 72% of total emissions. Cyclohexane and xylene were the major components during the emission. The filling process was the largest contributor in the case of unorganized emission. As far as end-pipe treatment was concerned, ultraviolet (UV) photolysis varied greatly between 12-80%, indicating unstable removal efficiency. Finally, several measures concerning whole-process control were suggested.
