EN The paper presents research into the possibility of reducing emissions of ammonia (NH3), which is the main component of post-process gases emitted from thermo-chemical treatment furnaces, particularly in the nitriding and carbonitriding of steel. The research involved testing the validity of an ATS system consisting of an Ammonia-Slip Catalyst (ASC) and a Selective Catalytic Reduction reactor (SCR) for the neutralization of dissociated ammonia and the secondary formation and reduction of nitrogen oxides (NOx). The results of the study show that the degree of reduction of ammonia is influenced by the operating temperature, the chemical composition and porosity of the catalytic bed, the temperature and duration of the nitriding process, the degree of saturation of the treatment chamber with ammonia, the temperatures of the post-process gases and the velocity and intensity of the post-process gases fed to the ATS. The results obtained provide insight into the positive rationale for applying this technology to industrial treatment furnace solutions. A procedure scheme and main guidelines for the realization of NH3 and NOx neutralization from the post-process gases of thermo-chemical treatment furnaces were prepared.
