1 Applying a Recognized HWC MACT Technology for CO 2 Capture with Low Energy Consumption COAL-GEN 2011 Robert E. Tang CEFCO Global Clean Energy, LLC

2 - 2 - Outline of Presentation Current U.S. EPAs MACT Compliance Issues and Carbon Captures Energy Consumption Conventional BACT vs. CEFCO MACT Technologies How the CEFCO Process Works Current Status of CEFCO Technology & Summary

3 - 3 - The Issue Current BACT Technologies for Carbon Capture Need to achieve MACT standards to provide 10 ppm of SO 2 and 5 ppm of NO X in Flue Gas for processing High Costs: Energy Penalty (33+% on Performance plus additional Parasitic Load) Current BACT users must combine multiple overlapping technologies to come close to meeting MACT requirements CEFCOs modularized segregated-capture Modules customizable to retrofit Power Plants based on needs

4 - 4 - CEFCOs Innovative U.S. MACT Solution Use Ewans shockwave free-jet collision scrubbing to capture MACT multi-pollutants* Cooper Process to convert all captured pollutants into recovered, valuable End-Products for sale US Patent Office Issued on November 30, 2010 under: 7,842,264 CEFCO Users benefit from: 1) Complying with announced EPAs MACT and HAP Requirements 2) Producing valuable End-Products – no longer cost-center + =

6 - 6 - CEFCO Patent Title – Key Concepts Title of the Patent: Process and Apparatus for Carbon Capture and Elimination of Multi- Pollutants in Flue Gas from Hydrocarbon Fuel Sources and Recovery of Multiple By-Products Key Concepts: Elimination of Multi-Pollutants (EPAs MACT, or near Zero Emissions) Low Energy Penalty or Parasitic Load Recovery of Commercially-Pure Sellable Products Pollution Control becomes profit-generator instead of cost-center 4 Modules for separate capture of each of 4 major groups of Pollutants

7 - 7 - Supersonic Free Jet Collision Shockwave Effect (Intense Pressure and Energy) Aerodynamic Recovery of P and T Subsonic Free Jet Effect Ewans Subatmospheric Reaction Zone (Adiabatic Conditions) t = time in seconds P = Pressure T = Temperature °F ( T) ( P) 100° t1t1 t2t2 tmtm 0 X,000° 300° 200° Ambient t m = time in minutes Conventional Thermodynamics and Chemistry Reaction Zone for Target Capture/Conversion by Reagent Comparison of Parasitic Load or Energy Penalty

8 - 8 - Seeing Shockwaves Being Formed Image: Schlieren Photography – multiple shockwaves generated by shuttle craft at much higher Mach speeds Image: Airplane beginning to cross sound barrier at Mach 1.0, showing first shockwave

9 - 9 - Free-Jet Reaction Zone Image: Schlieren Photography of Free- Jet Collision Zone inside adiabatic reaction chamber under CEFCO Technology

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

11 CEFCO Process Uses Supersonic Shockwaves CFD image: Accelerating steam to form a Shockwave Conventional BACT Processes Speeds = 50 ft/sec to several hundred ft/sec Reaching 1 st Shockwave at Mach 1.0 1,200 ft/sec

12 CEFCOs 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
