ABSTRACT
In the industrial world, scrubbers have been used for a long time. Even incinerators, which can be good pollution control devices in themselves, may require scrubbers to enable the emissions to meet the regulations. Application engineering for air pollution control equipment requires a knowledge of the process to which the system will be applied and of the specific equipment which will be utilized to control the emissions. Regardless of the vendor's name, applications engineering begins with some basic calculations. The basic calculations involve two areas: determination of carrier gas conditions, and determination of pollutant characteristics. Wet scrubbers may be divided into two major areas: particulate collectors and gaseous emissions control devices. All scrubbers utilizing liquids for gas absorption rely on the creation of large liquid surface areas through the use of a variety of mechanical methods. Wet scrubbers are mechanical devices that often perform chemical functions.
