Bronkhorst High-Tech BV the leaders in Mass Flow Meter / Mass Flow Controller technology for gases and liquids, Pressure Controllers and Evaporation Systems.
As a technique to reduce the level of Nitrogen Oxides (NOx) in boiler or furnace exhaust gases, Selective Catalytic Reduction (SCR) has been around for years. SCR is a technology which converts Nitrogen Oxides (NOx) with the aid of a catalyst into diatomic Nitrogen (N2) ans Water (H2O). A reductant agent is injected into the exhaust stream through a special catalyst. A typical reductant used here is Anhydrous Ammonia.
A customer of Bronkhorst, who has been selling and servicing boilers and pumps for commercial and industrial applications for over 50 years, had been using a mass flow controller (MFC) which was not reliable or robust enough for the application and thus their customers were suffering from loss of ammonia measurement and control.
In the NOx reduction system the mass flow controllers are used to control the flow of anhydrous ammonia into the exhaust gas of a boiler or furnace where it is adsorbed onto a catalyst. The exhaust gas reacts with the catalyst and ammonia which converts the NOx into Nitrogen and Water.
There are very strict federal and state air quality regulations that specify the allowable level of NOx which can released into the atmosphere and there can be very heavy fines if those levels are exceeded. The company needed to provide their customers with a reliable and robust solution. The application demands a robust and repeatable mass flow controller that is at home in industrial environments.
The Bronkhorst solution was to recommend a mass flow controller using the CTA (Constant Temperature Anemometer) technology which is ideal to avoid clogging in potentially polluted industrial gas applications, like the Bronkhorst MASS-STREAM mass flow controller. The straight flow path and highly repeatable measurement and control capability combined with the robust IP65 housing allows the Mass-Stream to thrive in tough applications.
The customer began installing the MASS-STREAM from a point when the old Mass Flow Controllers (MFCs) failed.
