CPI Installs RTO for Electric Vehicle Paint Shop Emissions


    Catalytic Products International (CPI) installed a Regenerative Thermal Oxidizer (RTO) in the paint shop at a battery electric vehicle (EV) manufacturer for the control of Volatile Organic Compounds (VOCs). 

    CPI RTO 45.95 EV Paint Shop VOC Control    

    The 45,000 SCFM TRITON Regenerative Thermal Oxidizer (RTO) will control VOC emissions from the primary paint booth, the oven, and touch-up and parts booth with +98% destruction rate efficiency (DRE). The RTO will achieve a thermal efficiency of 95% allowing for minimal gas consumption and operating costs.

    Thermal treatment of VOCs and other air pollutants works by a simple reaction of the harmful hydrocarbon-based air pollutants with oxygen and heat. In this environment, the VOCs are oxidized to form harmless inert by-products like CO2, water vapor (H2O), and usable heat. These harmless by-products are released to the atmosphere or used within primary or secondary energy recovery techniques to further lower the operational costs.

    CPI Regenerative Thermal Oxidizers (RTOs) are engineered to provide exceptional performance and reliability. During operation of the standard two chamber RTO, the VOCs are directed into one of the system’s regenerators, an internally insulated vessel containing specialized ceramic media which allows thermal rate efficiencies up to 97%. The contaminated gases are passed through the first regenerator where energy is transferred from the ceramic media to the gas in order to elevate the temperature. This elevated temperature approaches the ignition level for most solvents and is then directed from the ceramic bed into the combustion chamber. As the stream exits the ceramic bed and travels through the internally lined combustion chamber, minimal heat is added to ensure a proper oxidation temperature and a designed dwell time is maintained providing destruction of the VOCS at greater than 98% efficiency. The resultant clean, oxidized gases are directed to the second regenerator to absorb the heat energy before being released to the atmosphere.

    CPI worked closely with the customer and the paint finishing systems supplier to provide installation of the RTO, including engineering, design, rigging, and assembly. The installation of the RTO and related equipment included mechanical and electrical installation, forced draft booster fan, dampers, and exhaust stack. CPI was able to complete a good portion of the installation activities before the new unit arrived on site for final assembly. This approach, along with CPI start-up, commissioning and training, guaranteed that the entire system was installed correctly, returning the customer to fully operational status with minimal downtime.

    Since 1969, CPI has been Enabling Clean Production™ as a leading supplier of air pollution control solutions. CPI is at the forefront in providing industries including the automobile industry with solutions to their air pollution control needs.

    Today, CPI partners with its customers as a trusted resource in resolving the most complex air pollution and energy conservation problems. We provide our customers with innovative and cost-conscious solutions to their most complex VOC, NOx, and Odor pollution challenges. Our equipment is also at work meeting energy conservation strategies and minimizing greenhouse gas (GHG) emissions.
