Catalytic Products International (CPI) recently installed a Regenerative Thermal Oxidizer (RTO) at a Midwest USA building products manufacturer for the abatement of Volatile Organic Compounds (VOCs) from a coil coating process line.
- Process Type: Coil Coating
- VOC: Naphthalene and naphtha
- Process Air Volume: 30,000 scfm
- Control Type: Regenerative Thermal Oxidizer (RTO)
- Destruction Rate of Efficiency (DRE): 99%
- Installation: Turnkey installation
The 30,000 SCFM TRITON II -30.95 Regenerative Thermal Oxidizer (RTO) replaces a competitor’s smaller, underperforming rotary valve RTO which had reached the end of its useful life.
The new RTO will reliably destroy the VOC emissions from a coil coating process line with 99% destruction rate efficiency and 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 chemically 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 cost.
The Regenerative Thermal Oxidizer (RTO) system incorporates specialized ceramic media in the regenerator (heat transfer bed) to allow thermal efficiencies up to 95%. RTOs operate by preheating the process air as it passes upward through the first ceramic heat exchange media. This pre-heated air then exits the heat exchange media and enters a combustion chamber where it is heated to the setpoint temperature and oxidization of the VOCs is completed at greater than 98% efficiency. The resultant hot, clean air stream is then passed downward through the second ceramic heat exchange media bed where it is cooled before being released to the atmosphere.
Catalytic Products International (CPI) worked closely with the customer to design, fabricate, and install the Regenerative Thermal Oxidizer (RTO), new bypass Tee Damper and ductwork on the roof, booster fan, VOC entrapment system, exhaust stack, compressed air and natural gas piping. This approach, along with CPI start-up and commissioning, guaranteed that the entire system was installed correctly, returning the customer to fully operational status with minimal downtime.
