Review on Control of Emissions of Volatile Organic Compounds from Polluted Air

The most common air pollutants emitted from chemical, petrochemical and allied industry are Volatile Organic Compounds (VOCs). Stringent regulations on control of VOCs have been put up due to growing environmental awareness as they are main sources of photochemical reactions taking place in the atmosphere which may lead to various environmental hazards. It has been made mandatory for each industry or facility emitting VOCs to install proper VOCs control measures. Different control techniques are available for the control of VOCs emission based on destructive and recovery methods. Each method has its own advantages and limitations. Deciding the best applicable technique based on the type of process is of utmost importance as these VOCs have their own economic value. The paper reviews various available technologies for VOCs control along with its merits, demerits and applicability for each option. The paper aims at providing critical analysis of the requirements and accordingly deciding on the appropriate strategy to control VOCs
