The company Datwyler Pharma Packaging is extending their production facilities in the United States of America and in India due to growing market demands on their pharmaceutical packing materials.

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. The company has again requested Standardkessel Baumgarte GmbH to supply catalytic exhaust air cleaning systems for safe and environmentally friendly removal of volatile organic compounds. Each of the two systems is designed for an exhaust air volume flow of 6700 Nm³/h. This is the 3rd and 4th order for SBG from Datwyler after receiving the first two orders in 2016 and 2017.

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.
