A SMALL ASSIGNMENT FOR B.E 2NDYEAR 1 SEM IN E.S ON CONTROL OF GASEOUS POLLUTANTS IN AIR POLLUTION Control of gaseous pollutants from stationary sources The most common method for controlling gaseous pollutants is the addition of add-on control devices to recover or destroy a pollutant. There are four commonly used control technologies for gaseous pollutants: 1. Absorption, 2. Adsorption, 3. Condensation, and 4.Incineration (combustion) 1. Absorption The removal of one or more selected components from a gas mixture by absorption is probably the most important operation in the control of gaseous pollutant emissions. Absorption is a process in which a gaseous pollutant is dissolved in a liquid. As the gas stream passes through the liquid, the liquid absorbs the gas, in much the same way that sugar is absorbed in a glass of water when stirred. A...
