Most suitable for process streams that are relatively low in energy, Recuperative Catalytic Oxidizers (RCO) achieve VOC and HAP destruction at much lower temperatures than straight thermal oxidization, reducing fuel consumption.
Process air enters the oxidizer chamber and is heated before it passes through the catalyst. Air heats to the appropriate catalyst activation temperature, which varies from 350 – 650 F depending on the pollutant and the type of catalyst chosen. Exposure of the dirty air to the catalyst (in the presence of excess oxygen and at the necessary temperature) ensures the high destruction of VOCs, converting them into carbon dioxide, water vapor, and thermal energy. When incorporating a heat exchanger, the process air enters the heat exchanger and is preheated using the oxidizer’s exhaust energy before entering the oxidizer chamber.
Catalytic Oxidizers (CatOx) are an excellent air pollution control option in applications that need to treat low VOC process streams. Compared to other pollution control technologies, they are very cost-effective, have a low impact on the manufacturing process, and generate less NOx and CO due to their lower gas consumption.
Gas usage is a primary consideration in the ongoing operating cost of any thermal oxidizer. Oxidizers using a catalyst require less gas since VOC oxidation occurs at much lower temperatures than other oxidizer technologies. In some cases, the heat recovery is sufficient for the treatment process to operate auto-thermally, meaning that the energy evolved from the VOC destruction is enough to raise the process gas to the desired catalyst activation temperature, so no auxiliary fuel is necessary.
An Electric Catalytic Oxidizer uses electricity rather than gas and may be considered a more sustainable solution.
