CPI Installs RTO at Flavoring Manufacturer for VOC Control and Odor

    Catalytic Products International (CPI) installed a 25,000 SCFM Regenerative Thermal Oxidizer (RTO) at a Midwest flavoring manufacturer for the control of Volatile Organic Compounds (VOCs) and odors.

    During the manufacturing of flavor and taste solutions significant emissions of VOCs and odors are released into the environment.  While the compounds creating the odors may not be in sufficient concentrations to present a health risk, they can diminish the quality of life for the surrounding community.  A Regenerative Thermal Oxidizer (RTO) was selected as the most effective and cost-efficient option to ensure the destruction of the VOCs and the odor causing compounds from the production phases of this manufacturing process.

    The new 25,000 SCFM TRITON-25.95 Regenerative Thermal Oxidizer (RTO) will destroy the VOC emissions and odors from multiple spray dryers with +98% destruction efficiency (DRE) at a thermal rate efficiency (TRE) of 95%. 

    Thermal treatment of VOCs and other air pollutants works by a simple reaction of the harmful air pollutants with oxygen and heat. In this environment, the VOCs are converted into harmless inert byproducts, water vapor (H2O), and usable heat. These harmless by-products are typically released to the atmosphere, or in some cases use an energy recovery technique to further lower the operational costs.

    CPI Regenerative Thermal Oxidizers (RTOs) are engineered to provide exceptional performance and reliability.  During operation of the 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 redirected into a second regenerator bed to continue the energy transfer and oxidation cycle before being released to the atmosphere.

    CPI supplied a stainless-steel ductwork design that allows for future increase in spray dryer exhaust rates or additional process lines and provides crossover ductwork to include the existing oxidizer as a backup control device.  CPI provided on-site supervision to minimize the downtime associated with the installation of the RTO and associated ductwork.  This approach ensured that entire system was installed correctly, and the facility was back up and producing product with minimal downtime.CPI RTO Ductwork Flavoring-1
