A thermal catalytic oxidizer is a thermal oxidation system–such as a regenerative thermal oxidizer or a recuperative thermal oxidizer–where a catalyst is added to the process to transform the exhaust for Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs) into CO2, water and excess heat which are safely released into the atmosphere.

Basically, this catalyst allows the VOCs and HAPs to be processed at a lower temperature which saves the customer a significant amount of money because they don’t have to buy the extra fuel and time necessary to heat the system to the much higher temperature to destroy them.

This can be a tricky process though. Catalysts must be carefully selected to work with specific compounds and the amounts of those compounds present in the process stream. If the process stream changes somehow, either by adding some other compound to the process stream, or adding more or less of the selected compounds to be treated into the process stream, the catalyst might not be as effective and can even fail to transform the contaminants at all.

Getting the Right Mix for a Thermal Catalytic Oxidizer

As you can see, adding a catalyst to a thermal oxidizer requires a lot of specialized knowledge and engineering skill to set up an effective thermal oxidizer system that destroys the VOCs and HAPs quickly, completely and at the lowest possible cost.

At Epcon, our project engineers can help select the best possible setup–whether it is a recuperative thermal oxidizer, a regenerative thermal oxidizer, or some other configuration–to process the VOCs. Because Epcon’s engineers have experience working with catalyst manufacturers all over the world, they know how to pair the right catalyst with the right thermal oxidizer equipment to help reduce your operating costs.

Many thermal oxidizers are designed without the use catalysts, as the cost to install and replace the catalyst in the system can be very expensive. However, sometimes a catalyst is necessary or produces the optimal solution to a unique process stream.  Our engineers carefully assess the process and application, and then evaluate all options through engineering and cost studies to determine if a catalytic thermal oxidizer is the best solution for the customer’s operating needs.
