Air Pollution Control Images plus History of SO2 APC Equipment Temperature Inversions Urban Heat Islands Noise Pollution
1970 Clean Air Act – SO2 limits • 1990 CAA Amendments - SO2 trading
Air Pollution Control Equipment • Particulate Matter (3 types) • Acid gas removal • Prevention technology
Wet Scrubbers For acid gases (not just particulate)
Fluidized Bed Combustor Can PREVENT formation of NOx, and SO2 Sometimes considered part of “clean coal” technology
Now think about car emissions… (Review primary pollutants) CO2, CO, VOC/HC’s, NO, (NO2) What is the air pollution control device?
