Monitor ammonia during NOx-removal operations
The LaserGas III ammonia analyzer (photo) uses laser technology to measure NOx emissions from petroleum refineries, power plants, chemical, petrochemical and steel plants, and NH3 emissions in any type of NOx-removal system. The instrument helps operators to achieve better process control, increase the efficiency of emissions reduction, and decrease the use of costly consummables, such as urea (ammonia). The device uses a single-path configuration for the transmitter and receiver, allowing for easy cross-duct stack installation, says the company. The measurement principle is based on tunable diode-laser absorption spectroscopy (TDLAS). — NEO Monitors, Skedsmokorset, Norway
