One quarter of the world’s coal reserves are in the United States. The energy content of the nation’s coal resources exceeds that of all the world’s known recoverable oil.

During his campaign for the Presidency, George W. Bush pledged to commit $2 billion over 10 years to advance clean coal technology

CARBON CAPTURE POLITICS

In the coming years, power companies are to build about 150 coal plants to meet the growing electricity demand. Despite expectations almost none of the plants will be built

to capture the thousands of tons of carbon dioxide that will be generated.NYT, Feb. 20, 2007

SELEXOL CO2 ABSORPTION SIMULATION COMMENTS

1. NRTL bip regression method for partial pressure needed2. CO2 User Component (UC) behaviour to validate

3. SCDS Mass Transfer convergence sensitive with (UC)4. SCDS Mass Transfer matrix report to be simplified5. PR (H2O Immiscible) with special bip feature to prove6. Henry’s Law Coefficients for User Components7. Random and structured packing data very limited8. Sulzer packing sizing link needs finishing
