Abstract

As FT-IR remote sensing techniques become more accessible, there are increasing interests to apply this open-path measurement method to detect and measure airborne pollutants. Thus a research for VOCs emission pollutants in the petrochemical industry park is conducted. In this study, we focused on the identification of the gaseous pollutants as well as the location of the VOCs pollutants from different factories. Measurement is sampled at every half hour period to obtain the time series plots of observed gas concentration for the gaseous pollutants. Besides the inherent components in ambient air such as carbon monoxide, methane, and ozone, the results of the measurement indicate that the major pollutants detected in this industrial park include vinyl chloride, chloroform, hydrogen chloride, 1,2-dichloroethane, 1,3-butadiene, ethylene, propylene, n-hexane, acetic acid, methyl acetate and ammonia. Some of these toxic pollutants are carcinogens and also the chloride related compounds are potentially a threat to the depletion of ozone. All of these measurements indicate that the pattern of the pollutants for each location is significantly different from each other pattern. In addition, the concentrations and the presence of absence of pollutants were dramatically affected by wind directions. Under this case, suspicious polluting plants are successfully being identified by examining the pattern of compounds, pollutant's concentration time series, metrology, and manufacturing process.
