The Anguil Catalytic Recuperative Oxidizer destroys Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and odorous emissions that are often discharged from industrial processes.  The air pollution control device achieves emission destruction at significantly lower temperatures than thermal oxidation through the use of catalyst, converting pollutants to carbon dioxide, water vapor and heat.
How the Catox Works
VOC and HAP laden process gas is either pushed or pulled into a metal heat exchanger inside the oxidizer via a system fan.  The contaminated airstream is progressively heated while traveling through the heat exchanger towards the combustion chamber.  At the burner, the process gas is raised to the catalyst operating temperature.  As the heated gas passes through the catalyst, an exothermic (heat releasing) reaction takes place.  The pollutants are converted to carbon dioxide, water vapor and heat.
Once oxidized across the catalyst, the hot, purified air passes through the opposite side of the heat exchanger and releases thermal energy to preheat the incoming air.  The heat exchanger reduces the auxiliary fuel requirement, thus saving operating cost, allowing self-sustaining operation with no auxiliary fuel usage at Lower Explosive Limits (LEL) levels of 8-12%.  Finally, the cooler, purified air is exhausted to the atmosphere through the system stack.
