    Gas monitoring instruments and systems for DeNOx process control

    In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.

    Continuous emissions monitoring in cement kilns

    Various pollutants form in the cement manufacturing process, especially when alternative fuels and waste-derived fuels are used. Typically a cement kiln using these fuels is a required to monitor hydrogen chloride (HCl). Gasmet CEM II is EN 15267-3 approved for HCl measurement in 0 … 15 mg/Nm3 range.High process temperatures result in generation of more nitrogen oxides (NOx) than in typical municipal waste incineration.

    Chemiluminescense based analyzer for semiconductor applications

    NOx detection is an innovative approach in CMP (Chemical Mechanical Polishing) process control. CMP smoothens the wafer surface with a combined chemical and mechanical polishing procedure. During production, wafers are coated by a thin layer. To avoid damage to the wafer surface, for instance by stress cracks, the NOx emitted as soon as the wafer is plane and blank must be measured. Therefore, a high-resolution NOx-detector, capable of determining exactly when the polishing process must be stopped, is essential. This approach is used successfully in manufacturing and development lines worldwide, since 1996.

    Monitoring solutions for the De-NOx plants

    In recent years the number of Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) plants for De-NOx have increased significantly. Continuous analysis of NOx prior to the de-NOx plant is often required to measure the concentration generated by the combustion process. This may be required to provide feed-forward to the Ammonia/Urea injection system and also to allow the effectiveness of the reduction process to be assessed. Continuous analysis of NOx post-reduction is required to allow the effectiveness of the reduction process to be assessed. It may also be beneficial to monitor NH3 slippage at this stage by calculating from the pre and post NOx levels if excess Ammonia/Urea is being applied.

    Gas monitoring instruments and systems for process NOx measurement

    Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen dioxide NO2, as well as water vapor H2O, nitrous oxide N2O, carbon monoxide CO, carbon dioxide CO2 and ammonia NH3. The fixed installation products for these purposes are the Gasmet™ CEM II measurement system, and the Gasmet™ FCX Gas Analyzers, both of which utilize the FTIR measurement technique for simultaneous multicomponent analysis of the sample gas.

    Gas monitoring instruments and systems for nitric acid process

    Modern production method of nitric acid production may lead to generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in formation of nitrogen dioxide NO2 and nitrous oxide N2O. The NO and NO2 emissions can be reduced by use of Selective Catalytic Reduction unit (SCR), which deploys ammonia gas NH3 to limit emissions of NO and NO2. A modern nitric acid plant needs to monitor the emissions of these gases.

  • Nitrogen Oxides (NOx) monitoring

    Oxides of Nitrogen (NO/NO2/NOX) is the product of endothermic reactions within combustion engines and causes significant environmental pollution. The main source of NOX is from the engine of automobiles and these pollutants are harmful to humans in their respective forms or in the creation of ozone (O3) or acid rain. NOX is most prevalent in our societies as a contributor to asthmatic conditions as well as the photochemical smog found throughout many industrialized cities.

  • PLAZKAT systems for treatment of emissions in the petrochemical industry

    Today, the reduction of atmospheric emissions produced by the gas processing and petrochemical industries is an acute problem. The most widely used technique of exhaust gas treatment comprises complete burning, even though this method does not provide an adequate degree of treatment. Therefore, in this case PLAZKAT systems are a more effective solution for removing aromatic hydrocarbon from the emissions.
