Catalytic Products International (CPI) installed a Regenerative Thermal Oxidizer (RTO) at a Southeastern USA food processing facility for the abatement of Volatile Organic Compounds (VOCs), Hazardous Air Pollutants (HAPs), and odorous emissions from a meat curing and smoking facility.
The 25,000 SCFM Regenerative Thermal Oxidizer (RTO) controls the VOC emissions from multiple, batch smokehouse smokers 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 into 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 into the atmosphere.
CPI worked closely with the customer to provide a turn-key installation, including engineering, design and rigging of the RTO. The installation of the RTO and related equipment included stainless steel construction for the exhaust stack, booster fan, outside ductwork connecting multiple process exhaust ducts to the RTO, bypass and balancing dampers, and access doors.
