Catalytic Vs Thermal Oxidizers

Stelter & Brinck

When certain products are manufactured, harmful pollutants called VOCs, or volatile organic compounds, are generated and dispersed into the atmosphere. These VOCs have a negative impact on the health of our ecosystem and thus, environmental agencies have enforced emission rules throughout the years.

Oxidizers are one type of pollution control system that manufacturers install in order to adhere to environmental regulations. Catalytic Oxidizers and Thermal Oxidizers have been used to destroy VOCs for over 25 years. Please read our previous blog posts to get an idea on how Catalytic Oxidizers vs. Thermal Oxidizers work to destroy emissions.

While Thermal Oxidization is still the primary method of VOC destruction, Catalytic Oxidizers are more fuel efficient and have lower associated operating costs. Stelter & Brinck’s Catalytic Oxidizer further reduces manufacturers’ energy costs because it is standard with heat recovery. However, this is just one of the differences to note between Catalytic Oxidizers and Thermal Oxidizers; the others can be seen in the chart below.

-Used when flow of exhaust is relatively slow and the VOC concentration is high. -Cater to industries with larger volumes of low VOC concentrated exhausts.
-Used with lower temperature air streams. -Used with higher temperatures and for higher activity periods.
-Metal catalyst monoliths are used to destroy VOCs. -Used in more industries, since catalyst beds are sensitive to certain emissions.
– Larger initial investment due to the customized catalytic bed, but typically have a longer equipment life. -Smaller initial investment.
