  1. Air Emission Control Technology Frances A. Hardrick We Energies UWM Air Pollution Meteorology Class November 20, 2007

  2. Overview • Air Emission and Monitoring • Project Specifics • Careers

  3. How Electricity Is Made

  4. CEM in General Terms • Continuous Emissions Monitoring (CEM) • Sample the Flue Gas - One of Two Ways • Measure Directly at the Stack or Duct • Extract Sample and Transport to Analyzing Equipment • Log Results Electronically • Store Data for Historical Record

  5. What Drives Improvement? • We Energies Emission Controls Influenced by Environmental Commitment and Governmental Regulations • EPA Clean Air Act 1963/1970/1990 • Consent Decree 2003 • Performance Specification 11 (PS-11) 2004 • Clean Air Mercury Rule (CAMR) 2005

  6. Clean Air Act • EPA Clean Air Act 1963/1970/1990 • Sets Limits on Air Pollutants • Approves Plans for Reducing Air Pollutants • Assists in Supporting Clean Air Progress

  7. Consent Decree • Agreement to Significantly Reduce Air Emissions From Coal-Fueled Plants • Nitrogen Oxide (NOX) • Sulfur Dioxide (SO2) • Particulate Matter (PM) • Mercury (Hg) which was optional

  8. PS-11 and CAMR • Finalized Specifications and Test Procedures for Particulate Matter Continuous Emission Monitoring Systems (PM CEMS) at Stationary Sources • Finalized Clean Air Mercury Rule (CAMR) and Specification and Test Methods for Total Vapor Phase Mercury CEMS in Stationary Sources

  9. PM CEMS Duct Location

  10. P-5B Particulate Monitor • Probe and Analyzer Are Integral, One Unit • Measures at the Duct • Monitor Made to Withstand Outside Environment Power & Fiber Optics Box Protective Cover Protective Tube Attached here

  11. P-5B Particulate Monitor • This is a View With the Cover Removed • Uses Light to Measure Particle Concentration • Units in g/m3 Bolts to flange here Blower Electronics

  12. PM CEMS Stack Location Sample Line Run Sample Line Run Probe Location

  13. BetaGuard Particulate Monitor • Probe and Analyzer Not Integral • Analyzer Housed in Equipment Shelter • Probe at the Stack • Gas Sample Transported Via Sample Line

  14. BetaGuard Particulate Monitor • View of Analyzer Inside Shelter • Uses Beta Particle Technology to Measure Concentration • Units in g/m3

  15. BetaGuard Extraction Probe • Probe Shown in the Shop Sample Line Nozzle

  16. Mercury Analyzer
