Air Pollution Control

Air pollution control constitutes a variety of means employed to limit damage done to the atmosphere by the discharge of harmful substances and energies. A control strategy is a set of specific techniques and measures identified and implemented to achieve reductions in air pollution to attain an air quality standard or goal. This section discusses air pollution control strategies, engineering, and technologies, including the performance, potential, and limitations of the major control processes. We also critically discuss flare processes, thermal oxidation, catalytic oxidation, gas-phase activated carbon adsorption, and gas-phase biofiltration as well as the design, installation, and operation of air pollution process equipment.
