Abstract

In order to quantify the influences of volatile organic compounds (VOCs) emission from various sectors in petrochemical industry, an investigation of VOC emission characteristics was carried out in a petrochemical enterprise BS. The emitted VOC components and their corresponding concentrations were qualitatively and quantitatively analyzed in the organized and fugitive emission sources, factory boundary, as well as the sensitive sampling points. The emission characteristic and emission list were obtained at each sector of the enterprise. The results showed that a total of 25 substances were detected in the organized emission sources, production area, storage area and catchment pool, which were mainly alkanes, alkenes and alcohols. The featured pollutants were N-decane, N-nonane, N-octane isomers, N-heptane isomers, methanol and propane. Their emission were 8.70, 268.43, 120.04 and 0.0003 t, respectively. In terms of product output, their VOCs emission factors were 0.3631, 0.1624, 0.0118, and 4.06×10^-7kg/t, respectively. Correlation analysis indicated that the concentration level of setting area was significantly correlated to the level of the factory boundary (p < 0.01), and the concentration level of sensitive point was highly correlated with the level of the storage area, which showed that fugitive emissions has significant impact on the environment.
