CO2 Capture

CO2 Capture has the following options:

•None: (This is the default.) No CO2 capture is used.

•Amine System: This option puts an amine scrubber at the end of the flue gas train. This option requires post-combustion NOx control. (See Amine System (CCS System) parameters and Amine System (CCS System) results for more details.)

•Ammonia System: An ammonia-based CO2 capture process is used. This option requires post-combustion NOx and SO2 control. (See Ammonia System (CCS System) parameters and Ammonia System (CCS System) results for more details.)

•Membrane System: A polymeric membrane system is used for CO2 capture. This option requires post-combustion NOx and SO2 control. (See Membrane System (CCS System) parameters and Membrane System (CCS System) results for more details.)

•Solid Sorbents PSA: A solid sorbents-based pressure swing adsorption (PSA) system is used for CO2 capture. This option requires post-combustion NOx and SO2 control. (See Solid Sorbents PSA (CCS System) parameters and Solid Sorbents PSA (CCS System) results for more details.)

•Solid Sorbents TSA: A solid sorbents-based temperature swing adsorption (TSA) system is used for CO2 capture. This option requires post-combustion NOx and SO2 control. (See Solid Sorbents TSA (CCS System) parameters and Solid Sorbents TSA (CCS System) results for more details.)

•Oxyfuel Low S (<0.5%): This is an oxyfuel system for use with low-sulfur (<0.5%) coals. This option requires a specific configuration; we recommend that you start with the predefined configuration of the same name in the Configuration menu to access it and make any adjustments needed from there. (See FG Recycle & Purification parameters and FG Recycle & Purification results for more details.)

•Oxyfuel Med S (<=1.5%): This is an oxyfuel system for use with medium-sulfur (<=1.5%) coals. This option requires a specific configuration; we recommend that you start with the predefined configuration of the same name in the Configuration menu to access it and make any adjustments needed from there. (See FG Recycle & Purification parameters and FG Recycle & Purification results for more details.)

•Oxyfuel High S: This is an oxyfuel system for use with high-sulfur coals. This option requires a specific configuration; we recommend that you start with the predefined configuration of the same name in the Configuration menu to access it and make any adjustments needed from there. (See FG Recycle & Purification parameters and FG Recycle & Purification results for more details.)

•Chemical Looping: Post-combustion chemical looping uses a calcium looping (CaL) process for CO2 capture. This option requires post-combustion NOx control. It is not compatible with the hybrid cooling system . (See Chemical Looping (CCS System) parameters and Chemical Looping (CCS System) results for more details.)
