An Introduction to Air Pollution Control Systems

With the rise in factories and plants that release Hazardous Air Pollutants (HAPs) and Volatile Organic Compounds (VOCs) into the atmosphere, the need for air pollution systems cannot be stressed upon enough. These systems help to clear the air from harmful components like sulfuric gases, fumes, odours, and vapours. These gases pose a threat to the environment, local ecosystems and even human health, as they cause acid rains, smog, carbon emissions, etc.
Alarming Statistics About Air Pollution

Each year, 7 million people due to air pollution as the level of harmful pollutants remain on an all-time high across many parts of the world

14 out of the 15 top polluted cities in the world in terms of dangerous PM2.5 particles are in India

9 out of 10 people in the world are exposed to and breathe polluted air

Most of the world’s megacities exceed WHO’s guideline levels for air quality more than five times, which is the main risk to people’s health

120 million children under the age of five suffer from pneumonia, with 50% of child deaths from pneumonia being attributable to air pollution.
The Need For Air Pollution Control Systems

You won’t find a single industry that is not responsible for releasing harmful pollutants into the environment due to its production processes. The big-league players who have played a key role in harming the environment with harmful pollutants include, but are not limited to:

Petroleum
Energy production
Coal mining
Metal mining
Chemical
Waste management

Hence, air pollution control systems have become the need of the hour. The goal of these systems are:

Decreasing the release of harmful gases in the environment and controlling the spread of air pollution

Conserving natural resources to ensure they are present for our future generations

Decreasing the health threats that are the result of breathing and being exposed to polluted air
How Do Air Pollution Control Systems Work

Depending on the industry and the requirement, air pollution control systems may work in the following ways:

1. Chemical Modification

In this method, dangerous chemicals are converted into inert compounds, which is usually carried out with the help of flue gas desulphurization electrostatic precipitators. Moreover, to clean up the nitrogen oxide in the air, certain controls include selective catalytic reduction processes. With the help of these processes, the nitrogen oxides are regulated from non-moving sources, and the oxides of nitrogen are changed into molecular nitrogen.

In some cases, if the VOCs a recovery value, professionals may attempt to use methods like carbon adsorption, scrubbing and condensation to recuperate the materials.

2. Contaminant Destruction

This form of air purification is considered to be one of the most difficult as it involved reaching critical boiling points. This is needed to burn the chemicals from the air.

3. Hazard Removal

One of the most common and easiest forms of air purification processes, hazard removal, involves the use of air filter systems.

Multiple air pollution control systems use different types of technology and techniques to collect pollutants and conduct emission control efficiently. To know more about these systems, you can contact companies like Thermax!
