CO2 Capture for PC-Boiler Using Flue-Gas Recirculation:  Evaluation of CO2 Capture/Utilization/Disposal Options
Project # FWP49539

Primary Performing Organization:
Argonne National Laboratory

The principal contribution of this project is to develop engineering evaluations for the capture and recovery of carbon dioxide (CO2) from pulverized coal-fired power plants that are retrofitted for flue-gas recirculation. The analysis also will identify plants that may be retrofit candidates, and will consider the effects of different coals on CO2 capture as well as on the accessibility of sequestration options.

Because pulverized coal (PC) plants are the most common type of power plant, a CO2 recovery system that can be retrofit to PC plant boilers would have broad applicability.  In this type of plant, flue gas recirculation has the advantage of eliminating the need for N2/CO2 separation and sulfur separation, thereby permitting more economical CO2 recovery than is accomplished by competing amine-based systems.

The project will provide the power industry with a low-cost retrofit system that could remain in service during future upgrades at power plants.  The captured CO2 can be used for enhanced oil recovery, or otherwise sequestered.  In general, the project addresses both design and full energy-cycle issues pertaining to existing coal-fired power plants.  See graphic.
