Control of Specific Gaseous Pollutants topics include: Gaseous pollutants like sulphur dioxide emissions, nitrogen oxides control, carbon monoxide and hydrocarbons pollutant control. Gaseous pollutants can be controlled by using three basic techniques: Absorption: This technique involves bringing gaseous pollutants into contact with a liquid, such as water. The liquid absorbs the gas. Adsorption Incineration: This is a waste treatment process that involves the combustion of organic substances contained in waste materials.  These techniques can be used singly or in combination.    Some...
