Volatile organic compounds (VOCs) are mostly composed of carbon, hydrogen and usually oxygen. They may also contain nitrogen, sulfur and halogenated compounds such as chlorine, bromine and fluorine.
These compounds can be highly polluting and must be treated before being released into the atmosphere. The treatment can be done using thermal oxidation systems such as RTO (Regenerative Thermal Oxidizer), RCO (Regenerative Catalytic Oxidizer), DFTO (Direct Fired Thermal Oxidizer), etc. These systems combine compounds with oxygen to realize a combustion reaction, resulting in the production of carbon dioxide and water and thus eliminating their potential to harm the environment.
