Catalytic Products International (CPI) installed a 35,000 SCFM Regenerative Thermal Oxidizer (RTO) at a Northeastern USA manufacturer for the abatement of Volatile Organic Compounds (VOCs) from a paint booth operation.
The TRITON-35.95, 35,000 SCFM Regenerative Thermal Oxidizer (RTO) was installed as part of a facility expansion. The RTO controls VOC emissions, including toluene, ethyl acetate, and isopropyl alcohol (IPA) from a new paint line system consisting of four (4) new paint booths. The RTO will destroy the incoming VOC emissions from the coating process with 98% destruction efficiency (DRE) at a thermal efficiency of 95%.
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 to provide a complete turn-key installation, including engineering, design and rigging of the RTO. The installation of the RTO and related equipment included an engineered concrete pad drawing, ductwork and damper fabrication and installation, booster fan, 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.
