  1. Experience with Patented Shockwave Multi-Pollutant Capture Technology for Utility Power MACT Compliance Session: 6-C: Emissions Control Improvements POWER-GEN International ― 2011 • Robert E. Tang — CEFCO Global Clean Energy, LLC

  2. Outline of Presentation • How CEFCO Technology Works • Testing Facility at Wichita Falls Facilities (Peerless Mfg. Co.) • Updates and Current Status • MACT Compliance for • SO2 Capture consistently as “surrogate” for all Acidic Gases and HCl • Consistently far below PM10.0 MicronsCapture

  3. CEFCO — System Flow Diagram

  4. Profit from End-Product Streams Fine Particulates (< 2.5 Microns)

  5. Shockwave-Induced Intimate Mixing • Image: Schlieren Photography showing shockwave-induced intimate inter-mixing and re-combination of two gas-phase molecules Shockwave envelopment Inter-mixing Re-combination

  6. CEFCO’s Unique Reaction Mechanism • All flue gas must pass downward through Shockwaves “no escape” from “free-jet collision” and capture effect • Pollutants are first captured using Physics then converted into valuable end-products by using Chemistry

  7. Comparison of Parasitic Load or Energy Penalty CEFCO MACT Technology Supersonic “Free Jet Collision” Shockwave Effect (Intense Pressure and Energy) X,000° Reaction Zone Conventional BACT Technology Δ Pressure Δ Temperature Subsonic “Free Jet” Effect Ewan’s Subatmospheric Reaction Zone (Adiabatic Conditions) Conversion to End-State with Refrigeration/Cooling 300° Mechanical Switch Over 200° 100° Ambient Aerodynamic Recovery of ∆P and ∆T minutes extended minutes 1sec 2secs Time

  8. Ewan Technology: EPA MACT Compliant • EPA published its “Guide to Phase I MACT Compliance” for Hazardous Waste Combustors MACT ― May 22, 2002 • Ewan’s Technology was recognized and codified in 40 CFR §63.109 et al.

  9. CEFCO Process Test Site

  10. Video Tour of Test Site

  11. Successful Capture of Potassium Fertilizer and CO2

  12. Three Layers of End-Products Liquid Potassium Sulfite Fertilizer Potassium Sulfate Fertilizer Crystals Potassium Bicarbonate Crystals (CO2 Capture)

  13. Particulate Matter Test Results • Injected engineered PM0.1-10.0 Microns • Analysis showing Sizes are: 45% below PM2.5 Microns (have been successfully captured)

  14. Particulate Capture Results 35µm 30µm 25µm 20µm 15µm 10µm 5µm Laser cannot distinguish between Water Droplets and PM
