Question

Which technology combusts volatile organic compounds (VOCs) at high temperatures to convert them into carbon dioxide and water vapor?

• A. Vapor Recovery Systems
• B. Electrostatic Precipitators (ESP)
• C. Thermal Oxidizers
• D. Fabric Filters

Hint:

• Thermal Oxidizers (or incinerators) destroy VOCs and other combustible gaseous pollutants by burning them at high temperatures.
• The combustion converts VOCs into CO$_2$ and H$_2$O.
• Catalytic oxidizers use a catalyst to achieve combustion at lower temperatures.
• Vapor recovery systems aim to capture and reuse VOCs.
• ESPs and Fabric Filters are for particulate matter control.

Answer 1

The Correct Option is C

In the field of environmental management, particularly in the context of controlling air pollution, certain technologies are designed to manage and mitigate the release of volatile organic compounds (VOCs). Among the options provided, the technology that is specifically used to combust VOCs at high temperatures, thereby converting them into carbon dioxide and water vapor, is known as Thermal Oxidizers.

Explanation:

• Thermal Oxidizers: These systems are effective for treating VOCs and other air pollutants by employing high-temperature combustion. This process involves heating contaminated air, allowing the combustion of VOCs, and converting them into harmless compounds such as carbon dioxide and water vapor.
• Comparison with Other Options:
  • Vapor Recovery Systems: Primarily designed to capture vapors of fuels and solvents in tanks or during fuel transfer, but they do not combust VOCs.
  • Electrostatic Precipitators (ESP): Used to remove particulate matter from exhaust gases through the application of electrical charges, but not effective for VOC combustion.
  • Fabric Filters: Often used to trap particulate pollution, fabric filters are not capable of chemically transforming VOCs as thermal oxidizers do.

Thus, Thermal Oxidizers are the correct and efficient choice for the conversion of VOCs into carbon dioxide and water vapor through high-temperature combustion.
