  • Insitu analysis of ammonia slip and water vapor using a tunable diode laser for SCR/SNCR optimization and boiler tube surveillance in power plants

    ABSTRACT Environmental Regulations driven by the 1990 Clean 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 H?0 and Nj. The efficiency of the SCR SNCR is determined by monitoring the outlet for excess NH3. referred to as NH3 slip. The flue gas sample ...

  • Process analytics in vinyl chloride monomer (VCM) plants – Case Study

    Vinyl chloride monomer (VCM), made from ethylene and chlorine by pyrolysis, is the feedstock for the production of the very common plastic material PVC. Modern VCM plants use integrated processes, combining endothermic and exothermic reactions in an almost energy balanced operation. Plants optimize the product quality, plant safety and cost efficiency by using advanced process control equipment ...

  • Detect Leaks and Analyze Water Consumption with WaterSignal

    Did you know it will cost an estimated $1 trillion over the next 25 years to upgrade the nation’s water system to run more efficiently? While part of the problem is fragile, hundred-year-old water mains, it also falls on property owners to ensure they are doing their part to save water — for both the environment and their wallets. But how? ...

  • Analyzing the potential of community water systems: the case of AguaClara

    Successful maintenance of water provision has as much to do with the ongoing governance of these systems as the technology that goes into building them. This governance generally occurs at the community level. Most water systems are small and located in areas where there is generally not the profitability necessary to entice private investment. Understanding how community management can improve ...

  • Application notes: The Sievers InnovOx TOC analyzer: boiler water monitoring

    Background A boiler system is a semi-closed loop system in which water is heated and converted into steam to power a generator. The steam is then allowed to form a condensate and the process is repeated. Boiler water chemistry directly impacts boiler efficiency and fuel use. Improper water treatment allows scale formation and corrosion. Boiler scale and deposits form when impurities ...

  • Assessing performance of on-line nitrate analyzers

    Traditionally, activated sludge processes were designed to remove organics and suspended solids from wastewater. The justification for including nitrogen control in wastewater treatment facilities began with the need to protect receiving waters from the increasing problem of eutrophication and hypoxia (low levels of dissolved oxygen in bottom waters, generally less than 2 mg/l). One of the ...

  • Hydrogen Chloride Analyzer (HCl, H2O)

    LGR's Hydrogen Chloride Analyzer (HCl, H2O) provides sensitive measurements of HCl in ambient air or in industrial process flows (e.g., coal and cement exhaust streams) with extremely high precision and sensitivity. No longer do you have to spend a lot of money or wait a long time to measure HCl with extremely high sensitivity – LGR's HCl Analyzer provides measurements every second with ...

  • Analyzing for Trace CO and CO2 using a Total Hydrocarbon Analyzer

    Untitled Document The purity of Specialty Gases is determined by the measurement of various contaminants including Total Hydrocarbons. Low level measurements of carbon ...
