Air pollution control devices are a series of devices that work to prevent a variety of different pollutants, both gaseous and solid, from entering the atmosphere primarily out of industrial smokestacks. These control devices can be separated into two broad categories - devices that control the amount of particulate matter escaping into the environment and devices that control acidic gas emissions.
The extraction methods for each specific type of pollutant can differ. Although complex, these devices have shown to be effective in the past with the overall levels of emissions for many pollutants dropping with the implementation of these control devices.
Government and environmental groups require industries with medium to high VOC exhausts to reduce emissions by as much as 98%, there are a few ways to accomplish this:
- Incineration using an oxidizers
- Incineration using flare stacks
- Capturing and reusing solvent in a solvent recovery system
