CO2 Capture for PC-Boiler Using Flue-Gas Recirculation: Evaluation of CO2 Capture/Utilization/Disposal Options
Argonne National Laboratory
Project Number: FWP49539
This Argonne National Laboratory (ANL) project
will study the engineering aspects of retrofitting oxy-combustion to
existing boilers, including the effect of impurities and options for
carbon dioxide (CO2) transportation, use, and sequestration. For example, if the flue gas can be recycled before sulfur dioxide (SO2) scrubbing, the SO2
scrubber can be reduced in size, and significant cost savings are
possible. Engineering studies are necessary because of the different
physical properties of CO2 compared to nitrogen; these
effects include changes in radiation and the temperature profile in the
furnace. The analysis will also help identify power plants that may be
candidates for retrofit and consider the effects of different coals on
CO2 capture, as well as on the accessibility of storage sites for permanent CO2 sequestration.
