To fully analyze emission characteristics of volatile organic compounds (VOCs) from automobile coating industry in Chongqing City, related enterprises in the city were investigated in detail. The results show that the emission of VOCs from the automobile industry in Chongqing City was approximately 20 000 t in 2012. and the contribution rate of automobile coating was 83%. Most VOCs discharged from automobile coating industry were mainly from the use of coatings, diluents, curing agents and other materials containing VOCs. During the process of automobile coating. VOCs were mainly produced during the processes of spraying and drying. Besides. VOCs are partly produced during the processes of mixing paint, gluing, waxing, and repairing. The major ingredients of VOCs discharged during the process of automobile coating were methylbenzene, dimethylbenzene, trimethylbenzene, cumene. ethyl acetate, butyl alcohol, n-butyl alcohol, isobutyl alcohol, formaldehyde, butanone. acetone, cy-clohexanone, and methyl ethyl ketone. Besides, the ingredients of naphtha and aromatic hydrocarbon in VOCs need to be determined. The maximum ozone formation potential (OFP) of the above pollutants by the typical enterprises was 900-1 300 mg/m3. The production of secondary organic aerosol (SOA) was 3 636-11 073 t/a, which didn't include the contribution of aldehydes, ketones, ethers and esters to SOA, This research could provide scientific reference for the establishment of emission standard. control technology and management methods of VOCs from automobile coating industry that accord with economic and social development in Chongqing City.

In the past few decades, major advances in environmental protection within the coating application industry have been made. In spite of this technological progress, approximately 50% of industrial-solvent emissions still come from the paintapplication sector. The advances made in reducing emissions for plants requiring licensing have unfortunately had no influence on the environmental efforts of smaller companies. Solvent-reduced painting systems, such as high-solid paints, water-based coating, and powder coating have not been able to achieve acceptance, nor have innovative application technologies. The principal arguments against a conversion to these ecologically more favorable alternatives were related to cost and quality. Recently, the EU Solvent Directive (1999/13/EC) went into effect, aiming to significantly reduce industrial-solvent emissions. Up until this point, however, instruments enabling smaller companies to determine their solvent emissions and to simultaneously develop process-improvement potentials while keeping costs in mind have been missing. Using the mass and energy flow-management approach, cost structures and environmental benefits can be made transparent to the entrepreneur. The primary result of the research projects presented here is the computer-based mass and energy flow model called the individual computer-aided mass and energy flow model for the vehicle-refinishing sector (IMPROVE). It can be used as a detailed business-consultancy tool. Based upon this, practical guidelines were developed for easy orientation and activity planning. They can be used by companies to help them fulfill the requirements of environmental legislation and to display the benefits that can be achieved by various emission-reduction measures.
