The Anguil Regenerative Catalytic Oxidizer destroys Hazardous
Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and
odorous emissions that are often discharged from industrial
processes. The RCO achieves emission destruction through the
process of thermal and catalytic oxidation, converting the
pollutants to carbon dioxide and water vapor while reusing the
thermal energy generated to reduce operating costs.
How the RCO Works
Anguil has taken over thirty years of catalyst experience and
combined it with a quality Regenerative Thermal Oxidizer (RTO)
design, resulting in a system that achieves emission destruction at
temperatures 600 to 800 °F (315-427°C) lower than a standard
RTO. VOC and HAP laden process gas enters the oxidizer
through an inlet manifold to flow control, poppet valves that
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.
Catalyst placed near the combustion chamber helps oxidize the
VOCs and HAPs in an exothermic reaction. Since catalytic oxidation
occurs at lower temperatures, a layer of catalyst is used in
conjunction with the ceramic packing in an RTO or as a replacement
of a portion of the ceramics. As a result, fuel consumption
required to preheat incoming emissions could be lowered by 50 to 95
%, further reducing the carbon emissions and operating costs of the
already efficient thermal oxidizer. Depending on the process
conditions and gas prices, the payback on catalyst costs could be
as low as three months.
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.
