Exhaust Gas and Air Pollution Control – Oxi.X – Thermal Processes – Oxi.X – Regenerative Thermal Oxidizers
Dürr has a comprehensive range of systems that use thermal processes for air pollution control and is specially designed to meet customers` requirements. The thermal processes are based on the separation principle and use combustion to remove pollutants from exhaust air. In all cases in which pollutants cannot be collected for potential re-use respectively recovered, these VOCs have to be destroyed. This involves converting the pollutants in exhaust air into non-hazardous substances at specific temperatures, which allows the air to be purified.

Exhaust Gas and Air Pollution Control – Sorpt.X – Sorptive Processes
If the exhaust air comes into contact with a medium that the pollutant dissolves in more effectively than in the air, the pollutant moves into the medium and the clean air can be discharged from the system. The absorption and adsorption processes differ significantly in the way that they function. Adsorption is used for concentrating the pollutants. After this, pollutants still have to be removed from the exhaust air by another system. Sorptive systems are also able to recover solvents by high efficient distillation. By contrast, absorption removes pollutants from the exhaust air. It is generally used for cleaning flue gases. The two processes are described in more detail below.

Exhaust Gas and Air Pollution Control – Catalytic/Non-Catalytic Processes
Dürr offers a wide range of different catalytic air pollution control systems, which are designed to produce outstanding results with different types of pollutants and operating parameters. In order to describe the operating principle of Dürr systems based on the catalytic process, it is important to explain what a catalytic system is. First we need to highlight the differences between catalytic based Air Pollution Control Systems and other fundamental processes for air pollution control. Catalytic processes always involve the use of a catalyst. The task of the catalyst is to reduce the amount of activation energy needed to achieve a reaction. Dürr uses catalysts for oxidation processes and for reduction processes. Dürr offers a range of different systems perfectly satisfy customers` requirements.
