If the exhaust air stream is compatible with the catalyst
Catalytic incineration is an option if the composition of the VOC-laden exhaust air is known, stable, and suitable for the catalyst. The catalyst lowers the required reaction temperature, thereby enabling exhaust air purification with lower energy consumption than with purely thermal oxidation. Compared to thermal incineration, catalytic incineration is more dependent on the chemical suitability of the exhaust air stream(s); compared to Regenerative thermal incineration, the focus is less on heat storage and more on the catalytic reaction. A thorough analysis of the components is crucial: pollutant load, temperature range, and potential catalyst poisons determine whether the processes can be applied in a technically viable manner.
VEN CLEANAIR KNV Catalytic Incineration Systems
Catalyst, Process Air, and System Control Working in Tandem
VEN CLEANAIR KNV systems are designed specifically for the given exhaust air stream(s). This includes catalyst selection, preheating, airflow management, temperature monitoring, and protection of the catalyst during operation. Thus, the focus is not only on the reaction itself, but also on ensuring that the catalyst can operate continuously under suitable conditions.

Catalytic incineration is suitable for well-defined VOC exhaust air streams in which the constituents, concentrations, and temperature ranges can be reliably assessed. It is precisely this suitability assessment that determines whether catalytic incineration is technically and energetically feasible.
After-combustion processes reliably oxidize VOCs into CO₂ and water. Depending on the exhaust air stream(s), load, and energy requirements, three established processes are used. The following overview helps simplify the selection process for applications such as coating, drying, and adhesive application.
