Green Packaging Powered by Regenerative Thermal Oxidizer

Under more stringent environmental regulations and heightened consumers’ awareness, Stanley Package, as an eco-friendly flexible packaging manufacturer, has been dedicated to integrating environmental protection into its company culture and manufacturing practices.

Under the backdrop of even more stringent environmental conditions, Stanley Package has adopted the cutting-edge Regenerative Thermal Oxidizer to treat exhaust organic waste gas produced during manufacturing comprehensively to fulfill its company environmental obligation.

What is a Regenerative Thermal Oxidizer?

Regenerative Thermal Oxidizer is an extremely efficient, energy-saving, and eco-friendly equipment for medium- and high-concentration organic waste gas treatment. It uses high-temperature oxidation to decompose volatile organic compounds (VOCs) in organic waste gas into water and carbon dioxide, rendering the waste gas harmless.

Core Working Principle of the Regenerative Thermal Oxidizer

The RTO system operates based on thermal oxidation technology, which consists of three main stages:

Preheating Stage: The organic waste gas first enters the regenerator and is preheated to near combustion temperature by a ceramic packing bed.

Oxidative Decomposition: Preheated exhaust gas enters the combustion chamber. At temperatures ranging from 800°C to 1000°C, organic pollutants react with oxygen to produce harmless carbon dioxide and water vapor.

Heat Recovery: The heat generated during the oxidation process is absorbed and stored by the thermal storage element, which is then used to preheat incoming, lower-temperature exhaust gas, significantly reducing fuel consumption.

By periodically switching the airflow direction, the regenerative thermal oxidizer ensures effective heat recovery and continuous, stable exhaust gas treatment.

Excellent Performance of the Regenerative Thermal Oxidizer

High-Efficiency Purification Capacity

The regenerative thermal oxidizer has extremely high efficiency in purifications, usually over 95%, and correctly designed units have over 99%. This means almost all organic contaminants are converted to non-hazardous material with very little environmental impact.

Excellent Energy Savings

By utilizing very efficient heat storage materials for heat recovery, the regenerative thermal oxidizer decreases fuel consumption and operating costs significantly. The efficiency in heat recovery is more than 95%, making the system self-sustaining in operation when destroying moderate concentrations of waste gases of organics without needing external fuel.

Wide Application

The regenerative thermal oxidizer is available for the treatment of organic waste gas of any concentration and composition, and is particularly suitable for the treatment of medium- and low-concentration, large-volume waste gas. It is capable of handling huge amounts of low-concentration organic waste gas and adapting to the variation in the composition and concentration of VOCs in organic waste gas.

Intelligent Control and Safe Operation

Modern RTO systems are equipped with advanced automatic control systems for automated operation, reducing the need for manual intervention. They also feature multiple safety features, such as flameout protection, over-temperature alarms, and pressure equalization, ensuring stable and safe operation.

Applications of the Regenerative Thermal Oxidizer in the Flexible Packaging Industry

In the packaging production process, particularly in printing, laminating, and coating processes, various inks, diluents, and adhesives are used, which often contain volatile organic compounds.

The regenerative thermal oxidizer effectively treats the organic waste gas generated in these processes, ensuring that final emissions meet or even exceed environmental standards. The RTO system demonstrates excellent treatment effectiveness for organic waste gases such as ethyl acetate, butanone, n-butyl ester, cyclohexanone, and isopropyl alcohol generated during the production of aluminum foil packaging.
