ABSTRACT

Equipment used to control particulate emissions include gravity settlers, mechanical collectors, electrostatic precipitators, scrubbers, and fabric filters. The use of wet scrubbers to remove gaseous pollutants from contaminated streams is considered. Condensers can be located upstream of an incinerator, adsorber, or absorber. The two most prevalent definitions employed today for hybrid systems are The two major hybrid systems found in practice today include IWSs and dry scrubbers. Dry scrubbers offer potential advantages over their wet counterparts, especially in the areas of energy savings, zero liquid discharge, and capital costs. A preliminary screening, however, may be performed by reviewing the advantages and disadvantages of each type of air pollution control equipment. Gravity settlers, or gravity settling chambers, have long been utilized industrially for the removal of solid and liquid waste materials from gaseous streams. Centrifugal separators, commonly referred to as cyclones, are widely used in industry for the removal of solid and liquid particles from gas streams.
