Questions Brought Up Last Time What was the heat rate brought up
in the gasifier comparisons? Why use N2 as a transport gas and
not CO2? How are we absorbing CO2? What is a better definition of the
quench?

CO2 Sequestration
CO2 in our syngas is absorbed on Selexol to be selectively removed

CO2 Sequestration
Removed from the Selexol through multiple flashes
