Description

<p>This study has developed a new ambient pollutant emission inventory for large stationary sources classified by sectors, facilities, and fuel types. It utilizes emission factors and facility fractions derived from records of Research of Air Pollutant Emissions from Stationary Sources. Derived emission factors are consistent with existing studies. Emissions estimated in this study are consistent with emissions reported in Research of Air Pollutant Emissions from Stationary Sources. However, it is necessary to consider changes in emission factors caused by control technology developments in order to represent trends of emissions for past and future years. Vertical emission profiles for facilities have also been developed. Three-dimensional air quality simulations using emissions estimated in this study result in 1 μg/m3 increase and 2 ppb decrease of annual mean PM2.5 and daily maximum O3 concentrations, respectively, against simulations using existing emissions.</p>
