S30 -- Industrial Gas Cleaning and Air Pollution Control (SI)

Industrial gas cleaning performs one or more of the following functions:Maintains compliance of an industrial process with the laws or regulations for air pollutionReduces nuisance or physical damage from contaminants to individuals, equipment, products, or adjacent propertiesPrepares cleaned gases for processesReclaims usable materials, heat, or energyReduces fire, explosion, or other hazards

Equipment that removes particulate matter from a gas stream may also remove or create some gaseous contaminants; on the other hand, equipment that is primarily intended for removal of gaseous pollutants might also remove or create objectionable particulate matter to some degree. In all cases, gas-cleaning equipment changes the process stream, and it is therefore essential that the engineer evaluate the consequences of those changes to the plants overall operation.

In this chapter, each generic type of equipment is discussed on the basis of its primary method for gas or particulate abatement. The development of systems that incorporate several of the devices discussed here for specific industrial processes is left to the engineer.
