How Do I Choose Between a Thermal Oxidizer and a Catalytic Oxidizer?
Thermal and catalytic oxidizers both treat contaminant-bearing vapor streams by oxidizing suitable compounds, but they operate differently. A thermal oxidizer generally relies on a higher treatment temperature, while a catalytic oxidizer uses a catalyst to support oxidation at a lower operating temperature.
Important Selection Factors
- The contaminants and expected concentration range
- Required airflow and vacuum level
- Moisture, particulates, and other materials in the vapor stream
- Whether any compounds could interfere with or damage the catalyst
- Available fuel and electrical service
- Required destruction or discharge criteria
- Air-permit conditions and monitoring requirements
- Expected project duration and operating cost
A catalytic system may reduce the temperature and energy required for a compatible vapor stream. A thermal system may be preferred when catalyst compatibility is uncertain or when the application benefits from a non-catalytic treatment process. The final selection should be based on project data and applicable permit requirements.
