The complete system Set CEM 1

On the one hand driven by regulations regarding emission monitoring from the legislative and on the other hand demanded by plant operators who gain out of the analyses information regarding the process efficiency, for example in boiler control, emission monitoring is one of the most important topics in continuous gas analytics.     

It is possible to determine the concentrations of the gas components CO, CO2, NO, NOx, SO2, O2, HCl, HF, NH3 and H2O. The Set offers several versions to fulfill the demands of the market flexibly. Starting from a mounting rack with one analyzer and sample conditioning system options can be added easily and fast.

Mercury analyzer system HM-1400 TRX 

Monitoring mercury content in flue gases is becoming increasingly important. In the USA new regulations will come into effect in 2016, which could become a model for the entire EU. The total mercury analyzer in our portfolio was conceived as a standardized solution for continuous mercury monitoring: sample taking, sample preparation, and gas analysis that is automated and reliable.

HM-1400 TRX is a measuring system for fully-automatic and continuous mercury analysis in flue gas stacks gas by measuring mercury vapor (without wet chemistry). The system uses the extractive measuring principle and includes sampling probe and sampling line. The HM-1400 TRX monitors not only the performance of the mercury separators by measuring the total mercury concentration, but also reports and registers (also online) any violation of the high limits. As a result it is often possible to intervene directly in the process of the plant to be monitored and thus ensure reliable compliance with the specified limit values.

Technical Data

Measuring principle
Determination of the Hg° concentration of the extracted and conditioned sample gas by help of a dual beam UV CVAAS photometer. Ionic Hg-compounds are converted to Hg°inside a thermal converter.
Measurement
Concentration of total Hg in sample gas, indicated as Hg°(elemental)in μg/Nm3
Measuring ranges

0... 45/0 ... 75 to 0 ... 500 μg/Nm3

Benefits at a glance

  • Maintenance-free (6 months) dry reactor
  • Conversion of the sample gas into mercury vapor by a combination of thermal and dry chemical treatment
  • Continuous vapor measurement in a photometer
  • Low cross sensitivities
  • No fail-safe instrument air required
  • Larger measuring ranges with dilution device (option)
  • Integrated system to generate reference gas (option)
