Transcription

1 -1- OxyCoal Combustion Technology for CO 2 Capture Energy and Resources Conference 6 December 2007 The Chemists Club, New York

2 -2- Outline What is Driving OxyCoal OxyCoal Process Integration Air Separation Basics CO 2 Gas Processing CO 2 / O 2 Mixing An Integrated CFB Demonstration Project

3 -3- What s Driving Carbon Constraints Growing CO 2 Level (ppm) USA Greenhouse Gas Emissions by Sector, Agricultural 7% Commercial 7% Residential 6% Industry 20% Electrical Generation 32% Before Transportation 28% Electricity generation is the largest source of CO 2

4 -4- USA Approach to Climate Change CO 2 Goal of Legislative Proposals 14,000 10,000 6,000 2,000 Bush Administration Kyoto Protocol Business as Usual Kerry-Snowe McCain-Lieberman Sanders-Boxer (MM Tons CO 2 e) Udall-Petri* Bingaman* Bingaman* Udall-Petri* Olver- Gilchrest Common Themes Cap & trade focused Tradable on a monetary exchange Allocate CO 2 to sectors / companies at various levels Companies below their allocation receive tradable credits Companies above allocation must reduce emissions or buy credits USA CAP Recommendations *safety value

5 -5- The Importance of Coal USA Power Generation, 2005 (4.1 Trillion KWh) Coal Power Plants (100 MW or greater) Hydro 7% Other 6% 2005 Existing 401 Nuclear 19% Natural Gas 19% Coal 50% Constructed * Constructed * *EIA estimates of USA coal power generation, assumes 600 MW plant equivalent Coal to remain the dominant power source through 2030

6 -6- CFB Oxy-Coal Power Plant Supervisory Control/Load Following Steam Cycle & Generator ~ Inerts CFB Preheater Dust Collector CO 2 Purification & Compression CO 2 Ash Fan Impurities Mixer N 2 Coal O 2 Flow Control O 2 Cryo ASU Air
