Process

Catalytic Products International, Inc designs each QUADRANT NR-Series Thermal Oxidizer based on the exact needs of your application. With 43 years of thermal oxidizer design as a basis of our expertise, you can be assured that your QUADRANT NR-Series Thermal Oxidizer will be designed with the most appropriate features for your needs. The QUADRANT NR-Series Thermal Oxidizer is an economical solution to applications that:

  • Have high solvent loadings
  • Particulate or other contaminates
  • Ultra high VOC removal requirements
  • A need for high secondary heat recovery

NR Series Thermal Oxidizing Process The QUADRANT NR-Series Thermal Oxidizer is unlike any traditional thermal oxidizer. The system employees numerous features that have been developed and improved upon for over three generations.

These systems are easy to install, provide very high removal efficiency, and offer very low maintenance impact.

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

QUADRANT NR Series Thermal Oxidizer's are considered among the world's most advanced non-recuperative thermal oxidation systems. These specially designed and proven systems combine the basic principles of time, temperature, and turbulence to the fullest extent possible. The resulting effects provide you with exceptional performance, substantially reduced operating costs, and industry-leading reliability.

The QUADRANT Thermal Oxidation process begins with a booster fan designed to draw the volatile organic compound (VOC) laden process exhaust to the QUADRANT System. From there, the VOC-laden process air stream is then directed into the condensate evaporate section where it is preheated to eliminate any vapor droplets before entering the pre-heat burner.

A pre-heat burner is used to precisely maintain the combustion chamber operating temperature. The burner is designed to promote mixing of the exhaust gases with oxygen when fired through our specialized combustion system. This innovative design provides the highest degree of flame impingement and high-velocity mixing, leading to airflow and temperature uniformity for which QUADRANT Oxidizers are known.

The contaminated air stream next passes through an elongated high velocity combustion chamber. Here a series strategically placed mixing baffles creates turbulence and improves mixing, helping to prevent temperature stratification. From there the air stream rebounds 180 degrees to assure proper mixing of all the effluent constituents. Even at low flow conditions, this mixing action provides the highest possible temperature uniformity for industry leading destruction ability at the lowest operational cost.

Once mixed the air stream is held in the dwell chamber long enough to ensure complete combustion of the VOC's. From there the clean stream can be discharged to the atmosphere or to auxiliary heating systems such as; secondary air to air recovery, air to steam recovery, air to oil recovery, or directly back to the process in a closed loop direct recirculation process.

Your process is now in compliance with all clean air regulations !!

Features

Catalytic Products International has applied our 43 year history of providing innovative air pollution control solutions towards a line of highly flexible and efficient non-recuperative thermal oxidizers. Commonly referred to as afterburners, incinerators, or direct fired thermal oxidizers, our line of QUADRANT-NR Thermal Oxidizers routinely exceed all worldwide regulatory requirements while providing a level of sophistication that is unmatched in our industry.

QUADRANT NR-Series Systems are used on applications where primary air to air heat exchangers are not necessary. Special applications that have very high solvent concentration levels, low air volumes, high energy demand or secondary heat recovery needs, among others….can benefit from our QUADRANT NR-Thermal Oxidizers. In today's ever tightening regulatory climate traditional technologies such as scrubbers, strippers, flares, and the like can not achieve ultra high VOC elimination at an economical installed cost. Low cost - High Performance - Long Life are the key advantages of our QUADRANT NR-Thermal Oxidizers.

No other supplier of non-recuperative thermal oxidizers can match our extensive knowledge or equipment performance.

NR Series Round Modular Design Round Modular Design
All QUADRANT NR-systems incorporate a proven round design which protects against stress and fatigue commonly found in other systems that utilize an antiquated "square box" design.  Damaging thermal-mechanical stresses inherent in every thermal oxidizer are eliminated with the QUADRANT NR-Thermal Oxidizer and its round design.The modular design removes the heat exchanger from the combustion chamber to allow each component the ability to individually control growth. The modular design is key to long equipment life and the highest uptime reliability.
NR Series Internally Insulated Internally Insulated
All QUADRANT NR-Thermal Oxidizers incorporate a specialized internal insulation system designed to retain heat for low cost and cool shell temperatures.  The internal insulation works in conjunction with the round design to eliminate shell growth for industry leading uptime reliability and low maintenance.  The advancement of internal insulation is just one of the continued enhancements that we have introduced, all in an effort to provide longer lasting equipment with lower overall operating costs.
NR Series Center Combustion Tube and Burner Center Combustion Tube and Burner
One of the most unique features found in any QUADRANT NR system is the center combustion tube coupled with the preheat burner. This pairing of components has paved the way for QUADRANT NR systems to operate at the lowest temperatures while still providing the highest VOC destruction. Faced with today's compliance requirements the old design strategies of time and temperature are not enough. Only the QUADRANT NR system, by maximizing turbulent mixing, flame impingement, and temperature uniformity can assure users of low cost and ultra high destruction. The center combustion tube, when designed in conjunction with one of the specially selected preheat burners, is unmatched in our industry. QUADRANT NR systems have passed compliance tests worldwide, at lower combustion chamber temperatures than expected and even lower temperatures than we guarantee!!
NR Series pre-heat burner Pre-Heat Burner
The combustion system in every QUADRANT oxidizer is selected based on the exact needs of the user. QUADRANT NR systems offer a variety of preheat burner choices all designed for low cost operation, low NOx and CO emissions, and high performance. Advancements in our systems have allowed us to utilize special burner system for processing high concentration gas streams without adding excess dilution air (See our QUADRANT NRV Thermal Oxidizer for specifics). Users that normally rely on inefficient flares can now benefit from the ultra-high VOC destruction offered in our QUADRANT NR Thermal Oxidizers. Users of QUADRANT NR systems gain value and comfort from knowing their choice of pollution control has unmatched flexibility, even beyond what is standard in today's industry.
NR Series Temp Safety System Temperature Safety System
Every QUADRANT system is integrated to our customized PLC-control panel called TSS.  TSS communicates with the QUADRANT system and your process for optimal performance, safety, and reliability.  TSS optimizes fuel efficiency by managing temperatures, controlling drives, and positing valves.  This user friendly system provides automated operations, one button start-stops, self diagnostics, and data monitoring options for simplified maintenance and compliance verification.  Catalytic Products International, Inc. has vast processor experience and can integrate any industrial processor into your operations.
