Evaluation on VOCs terminal emission reduction technologies in rubber products industry in China

Rubber refining, calendaring, vulcanization and other processes in the production process of rubber products industry can produce waste gases containing volatile organic compounds (VOCs), with large emissions and high non-methane hydrocarbon contents, which can cause serious pollution to the surrounding environment. Therefore, it is urgent to effectively control VOCs emissions in rubber products industry. However, at present, the assessment of VOCs emission reduction technologies in rubber products industry is not perfect, and the benefits of VOCs terminal emission reduction technologies cannot be fully understood. By analyzing VOCs generation and emission characteristics of rubber products industry, and investigating the application status of different terminal emission reduction technologies, the evaluation index system with technical performance, economic benefits, resources and energy, environmental pollution as the primary indexes was established, and the fuzzy comprehensive evaluation method used to evaluate VOCs terminal emission reduction technologies. The aim was to screen out the best feasible VOCs terminal emission reduction technologies and provide evaluation basis and technical support for VOCs emission reduction in rubber products industry. The results showed that the carbon fibre adsorption-desorption method had good comprehensive emission reduction performance and was the optimal terminal control technology for VOCs emission reduction in rubber products industry.
