NOxCare - reducing emission of NOx
Our NOxCare products (formerly known as Reduktan) are used for reducing the emission of nitrogen oxides (NOx). NOx is the designation for NO2 + NO.
Formation of NOx: Greater or lesser amounts of NOx are formed by all types of combustion.The most important source of NOx is when some of the atmospheric nitrogen reacts with atmospheric oxygen in the combustion process (thermal NOx). In addition, the nitrogen found in fuel (oil, refuse, coal, etc.) reacts with atmospheric oxygen to form nitrogen oxides (fuel NOx). Together with sulphur dioxide, nitrogen oxides are the most important cause of acid rain. Acid rain causes considerable damage to nature and the environment. In addition, NOx contributes to the formation of ground-level ozone and the excess fertilisation of watercourses.
What is NOxCare? We currently market four different NOxCare products:
NOxCare is sprayed into waste gas containing NOx.This is done either at temperatures of 250-450º C, using a catalyst (SCR = Selective Catalytic Reduction), or at 1000-1100º C, without a catalyst (SNCR = Selective Non-Catalytic Reduction).NOxCare reacts with the nitrous gases and NOx is converted (reduced) into elementary nitrogen.Aqueous vapour is created as a by-product. Where is NOxCare used: NOxCare is currently used for treating the exhaust of diesel engines and flue gas from combined heat and power plants, waste incineration, refineries and other industrial burners. (In petrol engines, a three-way catalytic converter in the exhaust system solves the NOx problem).
