VOCs emission from an important industrial park in Tianjin, China

Abstract

Volatile organic compounds (VOCs) monitoring methods and monitoring plan is established, and typical large factories in eight industries (petroleum refining and petro chemistry, automobile manufacturing, printing and packaging printing, surface coating, furniture manufacturing, paint and ink manufacture, rubber manufacture and pharmaceutical research lab) in the important industrial zone in Tianjin (China) were surveyed and monitored. The monitoring data indicated that the main VOCs for most industries were BTEX, ester compounds, and methyl isobutyl ketone. VOCs concentrations of petroleum refining and petro chemistry, automobile manufacturing, and surface coating were at a high concentration levels (above 60 mg/m3) and exceed the emission control standard limit. The emission concentration of VOCs was successfully decreased by using the raw material and process that had low release of VOCs and efficient waste gas treatment facilities.
