PLC Flameless Combustion Catalytic Recuperative Oxidizer Waste Gas Treatment Catalytic Furnace

Flameless Combustion Catalytic Recuperative Oxidizer with Precious Metal Catalyst for efficient waste gas treatment solutions.

Our catalytic furnace offers exceptional versatility, capable of adapting to various catalysts to meet different chemical reactions and production requirements. Featuring advanced automation systems, the equipment ensures full automatic control of operations, minimizing manual intervention while maximizing production efficiency and stability.

Precise temperature control and stable operating performance guarantee efficient catalytic reactions, delivering significant economic benefits for industrial operations.

This Catalytic Oxidation system was designed and implemented by Jiangsu Ruiding Environmental Engineering Co. for Qingdao Siyuan Chemical Co., Ltd. The system effectively treats volatile emissions generated during chemical product manufacturing processes, as well as emissions from loading and transportation operations.

To meet Qingdao City emission standards while minimizing operational costs, we developed an economical solution featuring an innovative "cryogenic + CO" off-gas treatment process. This advanced approach replaces traditional cryogenic plus adsorption technologies commonly used for tank area gas treatment.

The treatment system handles 650 Nm³/h of tank area volatile gas and 350 Nm³/h of loading volatile gas. The 20×10 meter unit includes a three-stage condenser recovery system, reheater, catalytic reactor, electric heater, and other essential components, ensuring compliant emissions through the combined cryogenic + CO unit.

The project achieved mechanical completion on October 30, 2022, completed commissioning on November 20, 2022, and commenced full production operations in early December 2022.

Before entering the Catalytic Recuperative Oxidizers (CO), volatile organic compound (VOC) containing gas passes through a heat exchanger for preheating.

The preheated gas enters the CO system and is elevated to the catalyst's working temperature. An exothermic reaction occurs as pollutants convert into carbon dioxide and water vapor. The resulting clean hot flue gas then passes back through the heat exchanger, transferring thermal energy to incoming air before being discharged through a chimney.

Utilizing catalysts with different oxidation temperatures allows for lower inlet temperatures (typically 250-305°C). Heat released during oxidation reactions in the catalytic bed raises the chamber temperature, potentially reaching 300°C depending on VOC concentration and calorific value. The lower inlet temperature reduces energy requirements for maintaining oxidation temperatures, resulting in significant energy savings.

• Lower ignition temperature with higher purification efficiency and optimized heat exchange for reduced energy consumption and operating costs
• Compact equipment layout structure saves construction and installation expenses while ensuring convenient operation and maintenance
• Advanced waste heat recovery system maximizes heat recuperation, enabling normal production without additional fuel while generating superheated high-temperature steam
• Rectangular catalytic reactor design facilitates easy catalyst loading, replacement, installation, and maintenance procedures
• Palladium and platinum stainless steel metal honeycomb catalysts provide high activity, excellent high-temperature stability (up to 730°C), superior mechanical strength, extended lifespan (4-5 years), reduced resistance and pressure, and easy cleaning
