Catalysts for clean exhaust gas
from CHP units and industry

For a reliable design, we need information on the exhaust gas or exhaust air, the plant and the requirements. Important factors are the flow rate, the temperature at the intended installation point, the gas composition with the relevant pollutant concentrations and details of moisture, dust and possible catalyst poisons such as sulphur, siloxanes or silicones. We also need information on the plant itself: engine or combustion type, output, fuel, process description and mode of operation, i.e. continuous operation, part load or batch operation. On the requirements side, we need the permit or the emission values to be met and, if available, recent measurement reports. For retrofits or replacement elements, drawings, photos and dimensions of the existing housing are helpful, as are details of the available space and the permissible pressure drop. Not all data has to be complete to get started, as missing values can often be determined together. Send us the documents you have, and you will usually receive initial feedback within 24 hours.

An oxidation catalytic converter reduces carbon monoxide (CO) and formaldehyde through oxidation. An SCR catalytic converter (Selective Catalytic Reduction) minimizes nitrogen oxides (NOx) by adding a reducing agent (urea/AdBlue). We often combine both technologies.
