ABSTRACT
Based on the survey of 175 synthetic leather enterprises in Zhejiang Province, China, in 2014, this paper analyzes the control of volatile organic compounds (VOCs) and, ultimately, screened 161 key enterprises for further research. The results showed that most enterprises take measures to control waste gas; however, there is a distinct problem with the efficiency of exhaust gas collection. The industry used Solvent-based materials. The main VOC pollutants were DMF, toluene, methyl acetate, acetone, ethylacetate, and butanone. The VOC emission coefficient of the synthetic leather industry in Zhejiang was 0.168 kg·m-2. The industry includes polyurethane and polyvinyl chloride processes, for which VOC emission coefficients were 0.170 kg·m-2 and 0.142 kg·m-2, respectively. In addition, the emission coefficient of polyurethane wet processes was 0.191 kg·m-2 and that of dry processes was 0.179 kg·m-2. The emission coefficient for VOCs in post-treatment processes was 0.120 kg·m-2.
