Controlling VOCs Using Carbon Adsorbers
Raymond Ehrhard, P.E.
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 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.
The student is expected to read and review the
material contained in EPA Air Pollution Control Cost Manual Section 3
–VOC Controls, Chapter 1, (EPA 452/B-02-001).
The student must take a multiple-choice quiz consisting of
twenty (20) questions at the end of
this course to obtain PDH credits.
