Abstract: In combination with the production process investigations,field sampling and experimental analysis,the emission features of volatile organic compounds (VOCs) from raw material input to product output in the manufacturing process of a typical daily chemical enterprises in Guangzhou city were examined via material balance method.Results indicated that the mass concentration of VOCs of organized discharge detection port is basically identical.The mass concentration of VOCs of unorganized sampling at raw material mixing area is the highest.The mass concentration of limonene component is the largest both in organized discharge port and unorganized sampling.11 and 16 kinds of main VOCs were detected in the organized discharge and unorganized emission respectively.The main pollutant of this enterprise is limonene.The comprehensive emission factor of this enterprise was 0.199 kg/t based on the material balance method.
