| Abstract: | "Based on the demand for a volatile organic compounds (VOCs) emissions inventory for Beijing and for the reduction in VOC emissions, the three major solvent-based industries of automobile manufacturing, furniture manufacturing, and publication printing were selected for this study. In each case, emissions link negative pressure sampling was used in combination with laboratory-based GC-MS/FID to obtain the VOC spectra. The results show that there are significant differences in the emission of VOCs from the main stages of automobile manufacturing. Specifically, the paint-coating process was dominated by the emission of oxygenated VOCs and aromatic hydrocarbons, accounting for 71.26% and 27.14% of total VOC emissions, respectively. The proportion of aromatic hydrocarbons emitted during the varnishing process was very large (84.10%), which were mainly composed of the benzene series. The differences in VOC emissions during different stages of the furniture manufacturing process were small, mainly consisting of oxygenated VOCs and aromatic hydrocarbons, which accounted for 55.08% and 18.98% of the total, respectively. Of these, alcohols and esters were the main components. VOCs emitted from different stages of the publication printing process could not be monitored separately. Thus, the VOCs in the mixed exhaust gas from this process were mainly composed of alkanes and oxygenated VOCs, which accounted for 47.29% and 44.57% of the total emissions, respectively" |
