Catalytic Oxidizer Benefits and Industrial Applications

Benefits, Limitations and Uses of Catalytic Oxidation

Catalytic oxidizers are industrial air-pollution-control systems used to treat compatible volatile organic compounds (VOCs) and certain hazardous air pollutants (HAPs) in process exhaust. HiTemp Tech Corporation custom designs each system around the exhaust composition, flow, concentration, temperature and required emissions performance.

Potential Benefits of Catalytic Oxidizer Systems

Potential benefits of HiTemp custom catalytic oxidizer systems include:

1. Application-Specific Destruction Efficiency: System design, catalyst selection and operating conditions can be established around the required emissions performance.
2. Lower Oxidation Temperature: A catalyst can enable oxidation at a lower temperature than conventional thermal oxidation, which may reduce auxiliary-fuel use for a compatible exhaust stream.
3. Compliance Support: A properly designed and operated system can form part of a facility's emissions-control strategy; applicable permit limits and testing requirements remain project specific.
4. Custom Configuration: Catalytic systems can be evaluated for different industrial processes when the contaminants and operating conditions are compatible with the selected catalyst.
5. Operating and Maintenance Considerations: Lower operating temperature may reduce some thermal stresses, while catalyst inspection, cleaning and eventual replacement must be included in lifecycle planning.

Industrial Applications for Catalytic Oxidizers

Catalytic oxidation may be evaluated for industries that generate catalyst-compatible VOC emissions, including:

• Chemical Manufacturing: Treatment of compatible organic vapours from selected production and handling processes.
• Pharmaceutical Manufacturing: Control of characterized solvent and process-exhaust streams after catalyst compatibility is confirmed.
• Food Processing: Treatment of suitable organic vapours and odorous compounds where catalytic oxidation is technically appropriate.
• Printing: Control of compatible VOCs associated with inks, coatings, cleaning solvents and drying operations.
• Painting and Coating: Treatment of characterized solvent vapours from coating and curing processes.

Catalyst Compatibility and System Selection

Catalytic oxidation is not appropriate for every exhaust stream. Potential catalyst poisons, masking agents, particulates, condensable material and halogenated, sulfur-containing or silicon-containing compounds must be assessed. Airflow, VOC composition and concentration, operating schedule, required destruction efficiency and total lifecycle cost should also be evaluated.

HiTemp catalytic oxidizer systems are configured for the specific application. Expected performance, fuel use, maintenance requirements and compliance testing depend on the final design and operating conditions.
