The company Datwyler is building up a new production facility in Middletown, USA for the production of packaging materials for medical purposes. 

Datwyler 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, the company has requested Standardkessel Baumgarte GmbH to supply a catalytic exhaust air cleaning system for safe and environmentally friendly removal of volatile organic compounds. The system is designed for an exhaust air volume flow of 6700 Nm3/h.

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.
