  • Do I Need a NOx Converter On My Flue Gas Monitor?
    Most combustion sources must monitor their emissions of NOx (oxides of nitrogen) and report them to the local environmental protection authority.
  • Prevent Ammonia Slip and Gas Greater Efficiencies in Your Plant's NOx Reduction System with Quantum Cascade Laser Analyzers
    ) are techniques used worldwide to remove NOX. However, this process can result in a byproduct of unreacted ammonia or ammonia slip. Continuous measurement and monitoring of ammonia slip can be a challenge to ensure sample integrity is maintained, especially in high dust, high-temperature applications.
  • Urea Quality Monitoring
    The regulatory pressure on OEMs to reduce engine emissions will continue to increase well beyond the. current Euro 6, US 10 and Tier 4 criteria. Exhaust pollutants such as particulate matter (PM) and nitric oxides. gases (NOx) have been forced to be reduced by recent standards worldwide. A prime
  • Industrial Processing - Pickling Tanks For Stainless Steel
    Nitric acid is used to pickle stainless steel products to remove impurities and form a new surface layer on the material. To demonstrate compliance with environmental regulations, emissions of nitric oxide and nitrogen dioxide (collectively referred to as NOx) may be required to be monitored
  • Insitu Analysis of Ammonia Slip and Water Vapor Using a Tunable Diode Laser for SCR/SNCR Optimization and Boiler Tube Surveillance in Power Plants
    Environmental regulations driven by the 1990 Clear Air Act require Power Plants to reduce NOx emissions. SCR's and SNCR's reduce NOx emission by injecting ammonia into the combustion flue gas, which ideally reacts with the NOx to form H2O and N2. The efficiency of the SCR/SNCR is determined
  • Direct In Situ Zirconia Oxygen Analyzer (.pdf)
    The EXAxt Zircon Oxygen Analyzer (Model ZR402G) is used to monitor and control the oxygen concentration in combustion gases, in boilers and industrial furnaces, for wide application in industries which consume considerable energy-such as steel, electric power, oil and petrochemical, ceramics, paper
  • Under New Emissions Limits, Elsta Rises to the Challenge
    to reduce its carbon footprint and to minimize nitrogen oxide (NOx) emissions on its three gas turbines. Historically, it was difficult for Elsta to document the impact of these forward-thinking efforts due to less-than-sophisticated, data-tracking systems. Elsta's engineers had to manually monitor gas
  • Data Logging for Diesel Engine Emissions Control
    Recent local, state and federal mandates have required the reduction of harmful emissions, both particulate and NOx, from diesel engines used in off road equipment, generators, buses and construction equipment. A variety of control technologies exists, but each is best suited for a specific engine
