Industrial coating is one of the key sources for VOCs emission treatment, involving a number of emission processes in a wide range of industrial sectors. Analysis of the emission characteristics, treatment status and emission reduction potential of different industries is the basis for formulating differentiated control technical routes. According to the contributions to the total VOCs emission, seven industrial sectors, including manufacture of furniture, vehicles, automobile parts, containers, machinery, ships and steel structures, were selected to carry out the research on VOCs emission reduction due to source substitution, coating process and equipment improvement, fugitive emission collection and end treatment. VOCs emission characteristics and the application of VOCs control techniques in various key industrial coating sectors were summarized, the overall level of VOCs control in the whole process of different industrial coating sectors was evaluated, and the weak links of VOCs control were identified. The emission reduction potential of various industries under different emission reduction paths were estimated. The results show that: (1) There are many problems in the industrial coating sectors, such as insufficient substitution of low VOCs content coatings, low penetration of automatic coating methods, inefficient collection of fugitive emission, and low coverage of high-end terminal treatment facilities. Implementing the whole process control in the industrial coating industry has great emission reduction potential. (2) The emission reduction measures in different industrial coating sectors should be differentiated: in wood furniture, ship, steel structure and other coating sectors, the main emission reduction measures are source substitution and process improvement. The emission reduction potential accounts for 80.3%, 75.5%, 68.2% and 78.3% of the total emission reduction potential of the industry. The key emission reduction measures in automobile manufacturing, container and construction machinery manufacturing industries are unorganized collection and terminal treatment emission control, and the emission reduction potential accounts for 80.3%, 61.5% and 58.6%. There is great VOCs emission reduction potential in industrial coating sectors. . According to the characteristics of the sectors, different industries should carry out the whole process control should be carried out from the aspects of source substitution, improving automation, enhancing fugitive emission collection efficiency, and selecting suitable end-of-pipe treatment technologies.
