The Anguil Catalytic Recuperative Oxidizer destroys Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and odorous emissions at significantly lower temperatures than thermal oxidation technologies through the use of catalyst.
Lowering the oxidation temperature to between 350°F (177°C) and 850°F (454°C) offers many benefits:
- Decreased fuel usage
- Lower cost of construction materials
- Reduced thermal cycling
- Fewer Greenhouse Gas (GHGs) emissions; Carbon Monoxide (CO), Nitrogen Oxide (NOx)
- Smaller equipment footprint

- Selective Catalytic Reduction (SCR) systems reduce Nitrous Oxides (NOx) from industrial or manufacturing processes. We achieve NOx reduction through the injection of a liquid reductant (ammonia or urea) and the aid of emission catalyst. Once properly mixed and heated, the exhaust is directed through the catalyst chamber which reduces the NOx to elemental Nitrogen (N2). Through proper reductant selection and oxidizer design, upwards of 98% of exhaust gases are treated prior to being released to the atmosphere.
HOW DOES THE CATOX WORK?
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. The heat exchanger allows for self-sustaining operation with no auxiliary fuel usage at Lower Explosive Limits (LEL) levels of 8-12%. At the burner or electric heater, 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 as the pollutants are converted to carbon dioxide and water vapor. The hot, purified then air passes through the opposite side of the heat exchanger and transfers thermal energy via the heat exchanger to preheat the incoming air. Finally, the cooler, purified air is exhausted to the atmosphere through the system stack.
