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 ...

Continuous emissions monitoring solutions for H2S monitoring

To monitor H2S can be difficult. The UV absorption is without structure and the IR absorption has strong interference from H2O. The traditional way has been to remove all SO2 from the sample while keeping H2S, then convert H2S to SO2 ,and finally measure SO2 which then effectively yields the H2S concentration. The instruments used have often been ambient air SO2 analysers and extractive dilution systems. However, it is not unusual to experience practical problems with these type of ...
