Methods for Quantitative Analysis of Variability and Uncertainty in Hazardous Air Pollutant Emissions

In this paper, we employ bootstrap simulation methods to quantify both variability and uncertainty in air pollutant emissions. We illustrate the methods using examples of hazardous air pollutant (HAP) emissions from coal-fired power plants. Variability is the heterogeneity of values with respect to time, space, or a population. Variability may be quantified using frequency distributions. Uncert...

Projection of hazardous air pollutant emissions to future years.

Projecting a hazardous air pollutant (HAP) emission inventory to future years can provide valuable information for air quality management activities such as prediction of program successes and helping to assess future priorities. We have projected the 1999 National Emission Inventory for HAPs to numerous future years up to 2020 using the following tools and data: the Emissions Modeling System f...

Impact of H2S Content and Excess Air on Pollutant Emission in Sour Gas Flares

In sour gas flares,  content like any other components in inlet gas influences adiabatic flame temperature, which, in turn, impacts on the pollutant emission. Wherever flame temperature increases, the endothermic reaction between  and  is accelerated, which means higher  emission to the atmosphere. In this work, we developed an in-house MATLAB code to provide an environment for combustion calcu...
