CPI Installs RTO at Candy Manufacturer

    Catalytic Products International (CPI) installed a Regenerative Thermal Oxidizer (RTO) at a Midwest USA candy manufacturer for the abatement of Volatile Organic Compounds (VOCs).

    CPI RTO 6,000 SCFM Candy Manufacturing-1

    The TRITON 6,000 SCFM Regenerative Thermal Oxidizer (RTO) will control heptane emissions from several lines. The VOCs are emitted at the load cell weighing tanks and at the mixing kettle of each kitchen skid. The RTO was also sized to control additional kitchen skids at the facility. Regenerative Thermal Oxidization was selected for this application based on low solvent loading and the high integral heat recovery of an RTO. The RTO will destroy VOC emissions from the process with 98.5% destruction efficiency (DRE) and provide 95% thermal energy recovery.

    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 a ceramic media design in the regenerator (heat transfer bed) to allow thermal efficiencies up to 97%. 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 VOC’s 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.

    CPI provided engineering services, drawings, and support for a VOC capture system including capture hood and ductwork design. CPI worked closely with the customer’s mechanical contractor to design enclosures to meet the requirements of U.S EPA Method 204 Criteria for and Verification of a Permanent or Temporary Total Enclosure.

    CPI designed, fabricated, and delivered a fully skid mounted, pre-piped and pre-wired Regenerative Thermal Oxidizer (RTO) with the media installed on a CPI designed concrete pad. Upon completion of the installation by the customer and its contractor, CPI provided startup, commissioning and operator training. This approach ensured that entire system was installed correctly, and the facility was back up and producing product with minimal downtime.

    CPI has been “Enabling Clean Production Since 1969” and continues as a leading supplier of air pollution control equipment. CPI is at the forefront in providing industries including candy manufacturers with solutions to their air pollution control needs.

    Today, CPI partners with its customers as a trusted resource in resolving the most complex air pollution and energy conservation problems. We provide our customers with innovative and cost-conscious solutions to their most complex VOC, NOx, and Odor pollution challenges. Our equipment is also at work meeting energy conservation strategies and minimizing greenhouse gas (GHG) emissions.
