ENVEA - Model SM-5 -Total Mercury Emissions Monitor in Stack Flue Gases

• Certification ranges: 0-5 : 0-30; 0-45; 0-100; 0-1000 µg/m³
• Very high accuracy: <0,1 μg/m³ over 3 months
• Dynamic range switching for reliable measurement of mercury emission peaks
• Photometric measurement independent of the high-temperature converter to ensure very low maintenance times and costs
• High temperature conversion method: requires no reagent, water refill or cartridge replacement
• Does not require a calibrator to operate: reliability & reduced operating costs
• Modular mercury injection system at the probe or at the analyzer for complete AMS checks
• Probe head port for optionally connecting a calibration system
• No need for carrier gas, dilution or air conditioning, very low utilities consumption (no nitrogen required)
• Sampling box mounted on the stack: no maintenance required, no transport of reactive Hg
• Two different power sources (protected/unprotected) in order to separate and secure the measuring system
• Automatic backflush function
• Low maintenance and optimized operating costs
• Option: Performance Control System
• Very low certification range – High measurement accuracy
• Instrument certified to operate without calibration – Reliability & reduced operating costs
• Simple and robust design – Maximum availability, easy servicing with low maintenance costs
• Converter oven without catalyst – Requires no consumables, minimized operating costs
• Very low instrument air consumption – Lower operating costs
• Customizable heated sampling line – Remote installation for easy access to the analysis cabinet
• Over 20 years of expertise in mercury analysis – Guarantee of a high quality and high performance product

Hg CEMS monitor perfectly adapted for continuous mercury analysis in:

• Waste Incineration plants (industrial, medical, hazardous waste, sewage sludge…)
• Coal-fired power plants (before and after mercury absorbers)
• Cement kilns
• Determination of mercury at sulphur acid production plants
• Thermal treatment of contaminated soils, hazardous waste
• Metallurgical facilities with potential Hg emissions…
