Recuperative Catalytic Oxidizer
Also known as an RCO, the Recuperative Catalytic Oxi-dizer is most appropriate in process applications where particulate and catalyst poisons are not present and where concentrations of Vol-atile Organic Compounds (VOCs) are below 25% LEL. These systems incorporate a heat exchanger and precious metal catalyst on a monolithic substrate. By using a catalyst module, oxidation of the VOCs is achieved at significantly lower temperatures compared to straight thermal oxi-dation. The benefits of lower temperatures include less expensive materials of con-struction and a longer equip-ment life due to reduced ther-

mal expansion/contraction during shut-down and start-up. This also means lower operating costs due to reduced gas consumption and less potential for carbon monoxide and NOx emitted from the burner.
How Does It Work?
The process air is heated to between 300 °F to 750 °F prior to passing through the catalyst. The catalyst converts the VOCs into carbon dioxide, water vapor and thermal energy. The exhaust then passes through the heat exchanger, which is used to preheat the incoming VOC-laden process stream prior to entering the heating chamber.
