The project is to apply FTIR remote sensing techniques to continuously monitor VOCs emissions from petrochemical industrial parks. The main purpose is to identify types and sources of hazardous air pollutants (HAPs) and odor substances, so that consequent pollution reduction measures can be taken. In addition, as FTIR has unique advantages of rapid, continuous, measuring compounds simultaneously, highly sensitive, and long distance measurement, it has become a useful tool for air quality investigation during chemical accidents. There were total 12 villages nearby the three petrochemical parks being measured by FTIR. Air quality investigations of two chemical accidents occurring in National Tsing Hua University and Tofen Industrial park were also complete in January and August respectively. The project has established the pollution inventory for three petrochemical industrial parks, and clarified the major HAPs and odor substance. Ten factories were identified as having accidental releases with chemicals including hydrogen cyanide, N,N-dimethyl formamide, 2-butanone, 1,3-butadiene, vinyl acetate, acrylonitrile, ethylene oxide, dichloromethane, ethylene and acetylene. Having the major emission sources identified, each factory was required to explain the cause of releases, and meanwhile propose a pollution reduction plan. A factory with insufficient efficiency on its VOCs abatement system was identified to continuously emit a great amount of HAPs and odor. The factory is planning to construct a RTO system to reduce the amount of HAPs and odor being emitted to the air. Emission rate calculation method was applied to evaluate economic benefits derived from pollution reduction to encourage further pollution prevention or control measures to be taken. Calculating emission rates has assisted the factories to better understand the amount of loses related to accidental releases.
