    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.

    Flue gas denitration on-line continuous monitoring solution

    Nitrogen oxide (NOx) is one of the main sources of air pollution, not only it has significant influence on global warming, but also involved in the destruction of the ozone layer. Technical measures to control NOx emissions can be divided into two categories: one is so-called source control, the characteristic is by a variety of technical means, to control NOx generation in the process of combustion reaction (i.e., low NOx combustion technology). Another kind is the so-called tail control, the characteristic is...

    Industrial monitoring solutions for the de-NOx plants areas

    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...

    Process monitoring solutions for CO2 capture

    The process control of a CO2 capture plant needs good and reliable detection of gas phase NH3 and CO2. Measuring NH3 is a challenge due to the corrosive environment and high concentrations of NH3. Several places in the process needs to be monitored and to transport the sample is difficult. A large dynamic range is needed as the NH3 concentration can vary between 15% volume and a few mg/m3.
