MercSampler System ·

The automated XC-6000EPC MercSampler™ for Sorbent Trap Monitoring Systems is designed for continuous dual sampling of vapor-phase mercury emissions from stationary combustion sources, in accordance with the U.S. EPA MATS published in 40 CFR, Part 60-65, Appendix K, Subpart UUUUU and is MATS compliant. Performance Specification 12B: Specifications and Test Procedures for monitoring total vapor phase mercury emissions from stationary sources using a Sorbent Trap Monitoring System.The purpose of performance specification 12B (PS 12B) is to evaluate the acceptability of sorbent trap monitoring systems used to monitor total vapor-phase mercury (Hg) emissions in stationary source flue gas streams. These monitoring systems involve continuous repetitive in-stack sampling using paired sorbent media traps with periodic analysis of the time-integrated samples. Persons using PS 12B should have a thorough working knowledge of methods 1, 2, 3, 4, 5 and 30B in appendices A-1 through A-3 and A-8 to this Part 63.

Power generation utilities will be able to measure and obtain accurate and reliable mercury emissions data in order to determine emission levels and develop control strategies. Power generation utilities may choose from either Continuous Mercury Monitors or Sorbent Trap Monitors like the Apex XC-6000EPC for Mercury Emissions Monitoring. Sorbent Trap Monitoring System is designed for continuous sampling of vapor-phase mercury emissions from stationary combustion sources. Paired samples are extracted from the flue gas for the desired time period, from several minutes to several days. Samples are analyzed for determining time-averaged emissions. 

 

Meets U.S. EPA 40, CFR Part 75, Appendix K and Method 30B requirements (formerly Method 324).

The MercSampler is a fully automated meter console for paired sampling. It simplifies sampling requirements by automating:

  • Display of Real-Time Data
  • Management of Proportional Flow Control
  • Data Export for Report Generation
  • Temperature Control
  • Easily Transferred to a Microsoft Windows-Based PC Through Various Forms of Communication
  • Data Acquisition, Logging and Processing
  • Calculations
  • Leak Checks
  • Calibrations

Installation: 19" Rack Mount Standard. Available 8U Transport case, ShockMount Rack or Weather Resistant Aluminum Cabinet Configurations.

The XC-6000EPC MercSampler™ meter console captures all data necessary for paired sorbent trap sampling according to Appendix K and Method 30B. The meter console controls the sample flow rate proportionally to the stack flow rate and determines the standardized volume extracted through each sorbent trap. To collect the samples, two diaphragm vacuum pumps which work with the proportional valves and mass flow sensors, pull the samples through sorbent traps.

The XC-6000EPC MercSampler™ simplifies most sampling requirements by automating data acquisition, sample flow adjustments, leak checks, calculations, temperature control, and calibrations. Data is easily transferred to a Microsoft Windows XP-based PC through Ethernet, USB or an optional Wireless Interface.
