| Waste gas cleaning KS 98 application Control of the catalytic reaction for NOx reduction Description For the control of NOx emission, selective catalytic reduction (SCR process) has proved to be the most effective. Based on this process, the German ENKAT Company develops and manufactures highly efficient waste gas cleaning systems. In a catalyzer, nitrogen oxides are converted into nitrogen and water vapour (both are natural constituents of air) under the addition of ammonia and urea (carbamide). The process places high demands on the catalyzer (filled 100% with active catalytic material), and the load-dependent dosing of the urea. With an optimally designed plant, up to 90% fewer pollutants are discharged into the environment. This is achieved independent of operating conditions, very efficiently and without any problematic by-products. |
