CPI Replaces Thermal Recuperative Oxidizer with RTO at Web Coater

    Catalytic Products International (CPI) recently completed the installation of a new TRITON Series Regenerative Thermal Oxidizer (RTO) at a Northwest USA manufacturer of web coated material solutions for the abatement of Volatile Organic Compounds (VOCs). 

    This new 15,000 SCFM Regenerative Thermal Oxidizer (RTO) was installed to replace an existing Smith Thermal Recuperative Oxidizer rated at 65% thermal efficiency.

    Thermal Recuperative technology utilizes a principle in which the exchange of energy occurs by allowing heat from the combustion process to pre-heat the incoming process exhaust stream without the two air streams becoming mixed together or coming into direct contact.  The thermal efficiency of the heat exchanger depends directly on the number of passes the air is allowed to make before exiting. This concept, however, includes a ‘point of diminishing return’, which limits both the size and thermal efficiency of the heat exchanger. 

    TRITON Series Regenerative Thermal Oxidizers use a bed of ceramic material to absorb heat from the exhaust gas. It then uses this captured heat to preheat the incoming process gas stream and destroy air pollutants emitted from process exhaust streams.   Because the ceramic media is heat sink material it allows for much higher thermal efficiencies of 95% in a much smaller footprint.  

    The exhaust from the two product lines will be ducted to the TRITON Regenerative Thermal Oxidizer (RTO) to destroy the incoming VOC’s to +98% or to a lower limit of 40 ppm as C₁ at a thermal rate efficiency (TRE) of 95%. Since this was a replacement of an existing oxidizer, CPI could utilize the current VOC collection system and two T-damper assemblies to direct the exhaust airstream directly to the RTO.   

    CPI worked closely with the customer to minimize the downtime associated with the removal of the old oxidizer and installation of the new oxidizer. CPI provided on-site supervision to ensure coordination with the third-party sub-contractors and was able to complete a good portion of the installation activities before the new unit arrived on site. This approach guaranteed that entire system was installed correctly, and the facility was back up and producing product with minimal downtime.

    Since 1969 CPI has been providing industry leading printing and coatings companies 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.
