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 equipment used in treating gases, the most commonly used in air pollution control are fixed-bed systems and cannister types. This course describes the use of fixed-bed and cannister carbon adsorption units for VOC control.

In this course, the student will learn the theory of carbon adsorption and how it is applied to actual designs for controlling VOCs. The conditions for VOC adsorption and its effects on fixed-bed and cannister design equipment selection are presented. The course will be beneficial for a student with basic knowledge of air pollution control equipment and an interest in controlling VOCs for operations that use solvents. It is also an excellent overview for those professionals working in the field of air pollution control.
