Nitrogen Oxides - Abatement and Control Overview Nitrogen oxides (NOx) are a very important family of air polluting chemical compounds. This course explains why NOx are important air pollutants and how NOx are formed and react in the atmosphere. This course also includes the principles on which all NOx control and pollution prevention technologies are based, available NOx technologies for various combustion sources, and performance  more...

Controlling VOCs Using Carbon Adsorbers Overview In air pollution control, adsorption is employed to remove volatile organic compounds (VOCs) from gas streams, when a stringent outlet concentration must be met and/or recovery of the VOC is desired. Although there may be several types of adsorbants used, this course is oriented toward the use of activated carbon, a commonly used adsorbent for VOCs. Of the various types of adsorption  more...

Particulate Control - Baghouses and Filters Overview Fabric filter units are used in industry as an effective pollution control device for removal of particulate material within a captured air stream. This course presents the process descriptions of various styles of baghouses and air filter systems. Design and operating parameters are analyzed. The applicability of filter materials and operating principles are explained for a variety of  more...

Wet Scrubbers for Particulate Matter Control Overview Wet scrubbers are a pollution control devise used in the industry for removal of particulate material within a captured air stream. There are numerous types of wet scrubbers which remove both acid gases and particulate mater (PM). This course describes the commonly applied scrubber designs used to remove PM from stationary sources. Design and operating parameters are presented. Various  more...

Electrostatic Precipitators for Air Pollution Control Overview An electrostatic precipitator (ESP) is a pollution control device that uses electrical forces to move the particles out of the flowing gas stream and onto collector plates for particulate emission control. There are different configurations and types of ESPs designed and operated for removal of particulate mater (PM). This course describes the commonly applied ESP designs used to  more...
