Trace gas analyzers for ammonia in hydrocarbons applications
Introduction: Ammonia (NH3) is a well-known, widely spread air pollutant, which is present almost everywhere in low ppm/ppb concentrations. So this chemical can be found in various processes, where gases are the basic media, such as steam crackers producing gaseous hydrocarbons for further production steps like polymerization. Gases like this are for example Ethylene, Propylene and even so called cracker gas, which is mostly a mixture of above mentioned gases as well as Water and Hydrogen. The gases of interest ...

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 ...
