CPI Installs RTO for Flexographic Printing

    Catalytic Products International (CPI) installed a 6,000 SCFM Regenerative Thermal Oxidizer (RTO) at a Midwest USA flexographic printer for the abatement of Volatile Organic Compounds (VOCs) from a central impression press.

    CPI RTO 6.95 for Flexographic Printing

    The 6,000 SCFM TRITON-6.97 Regenerative Thermal Oxidizer (RTO) controls the emissions from a new flexographic impression press used for printing packaging materials. The RTO will destroy VOC emissions with +98% destruction rate efficiency (DRE) and a thermal efficiency of 97% allowing for minimal gas consumption and operating costs.

    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 greater than 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.

    CPI worked closely with the customer to minimize the downtime associated with the installation of the Regenerative Thermal Oxidizer (RTO) and delivered a fully skid mounted, pre-piped and pre-wired RTO with the media installed on the customer supplied concrete pad. Installation included rigging and assembly of the RTO, exhaust stack, forced draft booster fan and remote HMI control panel. CPI also provided startup services, a spare parts inventory, and compliance testing to validate the Destruction Rate Efficiency DRE of the RTO.

    Established in 1969, Catalytic Products International (CPI) continues as a leading supplier of air pollution control equipment. CPI is at the forefront in providing industries including packaging manufacturers and flexographic printers 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.
