Regenerative Thermal Oxidizer (RTO)
Anguil's Regenerative Thermal Oxidizer destroys Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and odorous emissions that are often discharged from industrial processes as a by-product of manufacturing. Anguil RTOs achieve emission destruction through the process of high temperature thermal oxidation, using temperature, residence time, turbulence and oxygen to convert pollutants into carbon dioxide and water vapor. Anguil systems allow emission destruction, while reusing the thermal energy generated to reduce operating costs.

How the RTO Works

VOC and HAP laden process gas is either pushed or pulled into the inlet manifold of the oxidizer via a system fan. Flow control or poppet valves then direct this gas into energy recovery chambers where it is preheated. The process gas and contaminants are progressively heated in the ceramic media beds as they move toward the combustion chamber.

Once oxidized in the combustion chamber, the hot purified air releases thermal energy as it passes through the media bed in the outlet flow direction. The outlet bed is heated and the gas is cooled so that the outlet gas temperature is only slightly higher than the process inlet temperature. Poppet valves alternate the airflow direction into the media beds to maximize energy recovery within the oxidizer. The high energy recovery within these oxidizers reduces the auxiliary fuel requirement and saves operating cost. The Anguil oxidizer achieves high destruction efficiency and self-sustaining operation with no auxiliary fuel usage at low concentrations.

APPLICATIONS

VOC and HAP Abatement

As is the case for many industrial manufacturing processes, emissions are best destroyed through the use of thermal and catalytic oxidation technologies. Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs) are destroyed through the use of high temperature combustion with direct heat recovery. The harmful air pollutants are converted to heat, water vapor and carbon dioxide, creating a destruction efficiency greater than 99%.

Air pollution control for the automotive industry

Anguil`s engineering expertise has led to numerous successful air pollution control and emission control installations in the automotive manufacturing industry. From painting vehicles to engine test stations and tire manufacturing, we have supplied oxidizers and heat recovery systems to both tier 1 and tier 2 automotive plants.
