Catalytic Products International (CPI) recently installed a new Regenerative Thermal Oxidizer (RTO) at a Midwest USA manufacturer of adhesive coated films for the abatement of Volatile Organic Compounds (VOCs) on a new, world-class coating and laminating line.
The 20,000 SCFM TRITON-20.95 Regenerative Thermal Oxidizer (RTO) will control VOC emissions from a new adhesive coating line and associated curing oven with +98% destruction rate efficiency (DRE) and 95% thermal efficiency.
This longtime CPI customer also operates a 25,000 SCFM TRITON-25.95 Regenerative Thermal Oxidizer (RTO) to control VOC emissions from three (3) existing adhesive coating lines.
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.
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 this longtime partner to provide a turn-key installation, including design, supply and rigging of the RTO. The installation of the RTO and related equipment included new engineered concrete pad design, process ductwork, bypass t-dampers and manual balancing dampers, booster fan, and exhaust stack. A high VOC hot gas bypass system bypasses clean hot air directly into the exhaust stack allowing the RTO to process and run almost double the VOC load and provide future operational flexibility.
