Reducing ammonia contents in exhaust gas streams is very important for a large number of applications. The main origins of ammonia emissions are livestock feeding and industrial processing, e.g. during the production of rare earth metals. We implemented a highly efficient plasma-based process using a dielectric barrier discharge reactor. The influence of the plasma discharge on the gas composition includes a fragmentation of many gaseous components. Therefore, we used a combination of a quadrupole mass spectrometer and an inline quartz-enhanced photoacoustic sensor for our analysis.
