AMESA-M

Mercury Sorbent Trap System

 

Meets the US EPA Performances Standard 12 B mentioned in the US Portland Cement Rules and the new MATS (Mercury and Air Toxics Standards).

 

More than 25 years of experience in continuous sampling of Dioxins and Furans (PCDD/PCDF) with the MCERTs & TÜV certified AMESA system, have benefited to the design of the of the continuous mercury sampler AMESA-M.

FEATURES AND BENEFITS

  • Mercury emission monitoring by sorbent traps is a good and practical alternative to conventional Hg CEMS with the following features and advantages:
  • First part in which the sampled flue gas is coming into contact is the trap therefore no risk of losses in sampling probe and sampling line
  • Low maintenance
  • Paired sorbent traps for quality assurance purposes
  • Suitable independant from the mercury concentrations. Limit of detection can be influenced by correct selection of the sample gas flowrate and the sampling period
  • Availability > 95 %
  • No negative bias due to e.g. saturated gold trap or Hg+ converter like it can happen with a Hg-CEMS
  • Sorbent Trap Monitoring System (STMS according to US-Environmental Protection Agency (EPA) performance standard 12B
  • Extracts a part of the flue-gas through a heated sampling probe
  • Sampling of mercury on paired sorbent traps (for QA purposes, as required by regulations)
  • Fully automatic sampling between 30 minutes and 4 weeks
  • Storage of operating data protocol
  • The AMESA-M system has a fully functional HMI at the probe
  • All system parts are installed in an IP54 enclosure (wall-mounted / cabinet version)
 
 

MAIN APPLICATIONS

  • Household waste incinerators and special waste
  • Cogeneration, gas turbines
  • Industrial boilers and furnaces
  • Power generation and combustion plants
  • Chemical & petrochemical plants
  • Cement plants
