  • Case study -New media makes RTO natural gas usage a rarity!

    Overview Tekra Corporation has always had an eye on their energy conservation. They are a custom coater of plastic films in Wisconsin where state regulations require over 98% of the Volatile Organic Compounds (VOCs) emitted from their process be destroyed in an oxidizer system. While considering their first oxidizer system, Tekra's Engineers did their homework and invested in an early ...

  • Case study - Printing: RTO solution

    Overview A flexographic converter needed to expand its business by adding an 8-color CI printing press to its existing press lines, and planned to add a second press later. The increase in emissions and flow from the new press was beyond the capacity of the existing 10-year old catalytic oxidizer. The customer needed a way to maintain compliance at an affordable cost. ...

  • Case study - RTOs leave nothing to HAP-penstance

    PROBLEM The United States EPA promulgated a ruling in 40 CFR, imposing strict new standards to reduce emissions of toxic air pollutants from the manufacture of pharmaceutical products, including prescription and over-the-counter drugs. The agency's rule was intended to reduce emissions of a number of air toxins and hazardous air pollutants (HAPs), including methylene chloride, ...

  • Case study - Engine test cell exhaust: RTO

    Overview A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished, the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also within this exhaust is a great deal ...

    Problem A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also, within this exhaust is a great deal of water vapor ...

  • Case study - Fiberglass polymer emissions: RTO control technology

    OVERVIEW A producer and supplier of corrosion resistant piping systems was looking to improve the reliability and lower operating expenses of an existing air pollution control system at their facility. During their manufacturing process, centrifugally cast mortar pipe systems are reinforced with a fiberglass polymer. This makes the pipe ideally suited for most corrosive piping ...

  • Rto & recuperative oxidizer pros & cons - Regenerative thermal oxidizer technology

    RTO technology has been developed for large volumes and low VOC concentration air pollution applications. The best example is spray booth exhaust where the volume of exhaust is high and VOC concentration is very low. Regenerative Thermal Oxidizer technology is based on using ceramic media as heat exchangers and switching values. Advantages High thermal efficiency ...

    Problem A producer and supplier of corrosion resistant piping systems was looking to improve the reliability and lower operating expenses of an existing air pollution control system at their facility. During their manufacturing process, centrifugally cast mortar pipe systems are reinforced with a fiberglass polymer. This makes the pipe ideally suited for most corrosive piping applications ...

  • Case study - RTO handles high VOC loading at silgan containers

    OVERVIEW Regeneration Game - Originally printed in The Canmaker Magazine - Sayers Publishing Group As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking plant in the ...

  • Upstream Particulate Removal for Rtos on Direct-Fired Osb Dryers – How much is enough?

    Abstract Since 1994 Regenerative Thermal Oxidizers (RTOs) have been applied to direct wood-fired OSB dryers for the purpose of VOC abatement. In early direct wood-fired OSB dryer applications many OSB producers felt that upstream particulate control was not necessary. However, the ash from the combustion of wood waste created a host of new operational problems for the RTO systems. This paper ...

  • Media replacement restores plant capacity and improves flow

    Reduced air flow capacity, large temperature imbalances in chambers, long start-up times, energy inefficiencies, and visual cracks and voids in the media bed are all indicators of an unhealthy Regenerative Thermal Oxidizer (RTO) that should be evaluated for media replacement. A recycling facility that processes waste bakery products was experiencing significant reductions in air flow capacity, ...

  • Case study - RTO: Efficient emission - Working with your pollution control equipment supplier can lead to reductions in both emissions and operating cost

    Untitled Document Robbie Manufacturing of Lenexa , KS is a leader in the production of printed shrink films, bags and pouches for a diverse range of demanding applications. In 2004 alone, the company was awarded a Good Buy award from Good Housekeeping magazine, achieved rigorous American Institute of Baking (AIB) certification and the highest award ( Best-in-Show for Wide Web ) possible from the ...

  • Case study - Increasing primary heat recovery

    OVERVIEW Tekra Corporation is a custom coater of plastic films in Wisconsin, where state regulations require over 98% of the Volatile Organic Compounds (VOCs) emitted from their process be destroyed in an oxidizer system. While considering their first oxidizer system, Tekra's Engineers did their homework and invested in an early model Regenerative Thermal Oxidizer (RTO). While at the ...

  • Case study - Oxidizer rebuild

    Industry Service and Maintenance Problem Anguil was called in to provide an engineering evaluation of a competitor's RTO that was suffering from visible deterioration and 'hot spot' issues. Due to the customer's production schedule, an internal inspection was not possible prior to the plant shutdown for repairs. Action ...

  • Case study - Increasing oxidizer capacity by 80,000 SCFM

    Overview A recreational products company bought a three year-old manufacturing facility with an existing regenerative thermal oxidizer (RTO) for the production of their outboard engine. They required emission control equipment to manage the volatile organic compounds (VOCs) emitted by the solvents used in the engine painting processes. The company wanted to minimize overall costs by using ...

  • Making Deficiency Corrections Can Improve Performance of Your WESP

    The panel/board industry carries a long history in the use of wet electrostatic precipitators (WESPs). Initially, WESPs were used as the sole emission control device prior to release of process emissions to the atmosphere. With consent decrees and new, more stringent regulations they became the pre-cleaning device of choice to protect regenerative thermal oxidizers (RTOs) from heat exchanger ...
