Emission of volatile organic compounds from coal combustion

Coal combustion processes tend to generate relatively small but statistically significant quantities of VOCs, toxic organic micropollutants as polynuclear aromatic hydrocarbons (PAHs), and methane. Difficulties and expenses involved in the monitoring of such trace elements in emission streams from combustion processes are reviewed. Researchers adopted a kinetic modeling and thermodynamic perspective for their attempts at making design predictions, which allowed them to develop a full analytical specification based on incomplete experimental data. Researchers used an analytical approach that targeted the thermodynamic properties and the kinetic pathways to evaluate the most likely route for PAH formation. The impacts of cooling trends on the constituents of waste gas streams are discussed.
