Mercury Sorbent Trap System
Amesa-M
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.
- 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)
- Household waste incinerators and special waste
- Cogeneration, gas turbines
- Industrial boilers and furnaces
- Power generation and combustion plants
- Chemical & petrochemical plants
- Cement plants
