Catalytic Oxidation
We have already proven our worth in the following industries, sectors, and applications:
Chemical and pharmaceutical industries, semiconductor and automotive industries, solar and recycling industries, printing and coating industries, surface finishing, painting, paint and varnish manufacturing, plastics processing, contaminated site remediation, odor control, biogas, landfill and low-temperature gas purification, and much more.
Prantner exhaust air purification systems are used in all these areas. With minimal energy consumption, they ensure reliable compliance with regulatory requirements. Ask about our systems for autothermal operation—you too can rely on energy savings! With the appropriate concentrations of your pollutants, our systems can even generate valuable energy.
The process exhaust air is drawn in by a fan and first preheated in a heat exchanger using the purified exhaust air. An electric heater or gas burner brings the exhaust gas stream up to the required reaction temperature, after which it is oxidized into carbon dioxide and water in the catalytic reactor. The oxidation takes place in a specially designed reactor. At higher pollutant concentrations (from approx. 3 g C-equiv/Nm³), autothermal plant operation is possible. This means that no additional energy is required for the conversion of the pollutants. The plant is controlled and monitored via an instrumentation and control system with a programmable logic controller (PLC), optionally also with remote monitoring or integration into a process control system. The systems can be equipped with explosion protection devices, such as concentration monitoring systems (FID, FTA, IR, WT), detonation arresters, and pressure relief devices.

FAQ's
Unlike thermal afterburning, catalytic afterburning operates at significantly lower temperatures. Advantages: lower energy consumption, including autothermal operation; reduced operating costs; and a more compact system design.
Yes, but fluctuations in composition, concentration, and temperature must be taken into account during the design phase. Prantner develops process-specific solutions with appropriate control technology for this purpose.
Prantner's catalytic afterburners are equipped with heat recovery systems to efficiently recover process heat and minimize energy costs.
Certain substances (known as catalyst poisons) can damage the catalytic converter. Therefore, a precise analysis of the exhaust gas is essential. Prantner provides professional support for measurements and analyses.
As a rule, it is possible to switch to a catalytic process, which also has significantly lower operating costs due to its lower operating temperatures.
Our systems are flexible and can be used for a wide range of throughput rates. Thanks to the container-based design favored by Prantner, this range can also be expanded in a modular fashion.
Emissions from production processes, which typically exhibit highly fluctuating concentrations, are treated in an “auxiliary unit” through several process steps. They are then fed into the exhaust air treatment system and cleaned to levels below the required limits.
Catalytic processes are ideally suited for electric operation. This electric mode of operation can also be perfectly combined with regenerative energy recovery or concentration.
Yes. Secure remote connections allow you to monitor operational data in real time, adjust settings, and perform maintenance and diagnostics efficiently. This increases system availability, operational reliability, and efficiency.
Yes, the system can be designed to handle fluctuating concentrations of process air. Various technical solutions, such as smoothing filters, allow for flexible adaptation. This ensures that the system continues to operate efficiently and safely even under changing operating conditions.
