Services & solutions for exhaust air purification and process heat re-utilization      

Exhaust air purification

The state-of-the-art technology of Dürr Systems AG guarantees efficient elimination of hazardous components in exhaust gases and residues while ensuring a high level of process reliability and reduced energy consumption.

Thermal oxidation is usually applied to reduce the combustible components in the exhaust air, such as Volatile Organic Compounds (VOC). Catalytic oxidation can be applied to reduce other components such as nitrogen oxides (NOx) at lower temperatures. Absorption is used to remove undesirable by-products of the combustion or components with a negative effect on the catalyst, for instance sulfur oxides (SOx). When the concentrations are relatively low adsorption is used to concentrate the components in the exhaust air.

Process heat re-utilization

With the energy efficiency technology of Dürr Systems AG, such as the "Organic Rankine Cycle”, remaining process heat can be re-utilized in an optimal way thereby reducing the CO2 footprint.

When there is a surplus of thermal energy at temperatures ranging between 90°C and 600 °C, the Organic Rankine Cycle (ORC) is a key technology used to generate electricity. Dürr has developed a series of standardized compact modules with a capacity range from 40 kW to 1.000 kW electrical output. These machines are especially suitable for applications with surplus heat from decentralized heat sources.
