Wet Scrubbers for Particulate Matter Control
Raymond Ehrhard, P.E.
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 scrubber types such as Spray Tower, Venturi,
Cyclone and others are reviewed in this course.
In this course the student will be able to
evaluate the advantages and disadvantages of various wet scrubber options as
they apply to emission sources and PM size ranges. Optimizing scrubber
operation is also presented. The course will be beneficial for a student with
basic knowledge of air pollution control equipment and an interest in
controlling particulate emissions. 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 6 –Particulate Matter
Control, Chapter 2 - Wet Scrubber for Particulate Matter, (EPA 452/B-02-001).
The student must take a multiple-choice quiz consisting of
twenty-five (25) questions at the end of
this course to obtain PDH credits.
