Abstract:VOC emission compositions from solvent use factories in Beijing were measured using canister-GC-MS/FID analysis system. Aromatics (22%~55%) and alkanes (13%~44%) were major species in auto-painting factories while alkanes (43%~71%) and oxygenated VOCs (17%~19%) were dominant in printing factories. VOC species emitted from electronic lithography industries were characterized as high content of acetone (10%~18%), while the proportion of other VOC components were quite discrepancy as to different manufacturers. VOCs treatment facilities, such as the catalytic combustion system, could re-shape the VOC profiles from the factories. Comparing with previous studies, our results showed that the printing profiles were similar, in which alkanes and aromatics were the most abundant species, while the profiles of auto-painting were very different from the others, very likely due to changes in the paints.
