Catalytic exhaust air purification

Technical Data Reference Sheet


The company Datwyler extend at the Kesurdi Village, India the facility for the production of packaging materials for medical purposes and  is committed to protect the environment and to make sure that no polluted exhaust air is emitted at any time.

Therefore, exhaust air is, at a low oxidation temperature, to be cleaned to the fixed emission limit values before it is discharged into the environment.



Therefore a catalytic exhaust air cleaning system for safe and environmentally friendly removal of volatile organic compounds will be installed.

By the use of a catalyst, the required oxidation temperature for the conversion of the organic compounds is lower than with thermal oxidation. The catalytic reaction releases thermal energy during oxidation. By using a highly efficient heat exchanger, autothermic operation is already possible at low VOC concentrations. Heat recovery takes place recuperatively in order to ensure safe and reliable separation of exhaust air and clean air. The optimized controls ensure operation in a large turn-down range and at various VOC concentrations without supplementary energy.

With the suggested process and the quality standards applied, all of the customer-specific demands can be met, including calorific efficiency and availability.

"The purification of waste gases and process gases is increasingly becoming a core issue in the design of plants due to the increasing environmental requirements. With our processes, we can not only clean the gases, but also make the ingredients available for recycling."
