Consider advanced modeling to control air emissions

摘要

Nitrogen oxide (NO_x) emissions are considered one of the six common air pollutants by the Environmental Protection Agency (EPA). A major NO_x source is the burning of fossil fuels by fired heaters and furnaces. The Clean Air Act requires the EPA to set National Ambient Air Quality Standards (NAAQS) for controlling NO_x emissions. To meet these standards, the hydrocarbon processing industry is adopting various technologies to reduce NO_x emissions. The technology selected usually depends on the NO_x emission requirement.
