Wet Scrubbers – Design of Spray Tower to Control Air Pollutants

Abstract

Wet scrubbers are compatible and effective air pollution control devices to arrest particulate matters and polluting gases coming out of industrial processes as air polluting emissions. There are various types of wet scrubbers but the present paper deals with Spray Towers and its design. The author of the present paper designed the Spray Tower for a 100 TPD cement plant based on Vertical Shaft Technology (VSK) after monitoring the air emissions in regard to designed parameters under variable conditions on a time scale. The efficiency of the designed Spray Tower has been to the tune of more than 95 percent.
