High solids flux circulating carbonation reactor

A system, the system comprising:

• a circulating fluidized bed (CFB) carbonation reactor;
• a separation device;
• a splitting device;
• at least a fluidized bed heat exchanger, wherein:
• the CFB carbonation reactor is configured to:
• receive a metal oxide (MeO) solids stream and a flue gas stream and form a metal carbonate (MeCO3) rich solids stream and a flue gas stream depleted in CO2, and
• forward the flue gas stream depleted in CO2 and the MeCO3 rich solids stream to the separation device;
• the separation device is configured to separate the flue gas steam depleted in CO2 from the MeCO3 rich solids stream and forward the MeCO3 rich solids stream to the splitting device;
• and
• the splitting device is configured to separate the MeCO3 rich solids stream into at least a first MeCO3 rich solids stream and a second MeCO3 rich solids stream;
• at least one pipe for providing the at least a first MeCO3 rich solids stream to the fluidized bed heat exchanger to form at least a first cooled MeCO3 rich solids stream and a second cooled MeCO3 rich solids stream;
• at least one pipe for providing the at least a first cooled MeCO3 rich solids stream from the fluidized bed heat exchanger to the CFB carbonation reactor at a first location;
• at least one pipe for providing the at least a second MeCO3 rich solids stream to the CFB carbonation reactor at least a second location separate from the first location;
• and
• at least one pipe for providing the at least a second cooled MeCO3 rich solids stream to the CFB carbonation reactor at a third location separate from the first and second locations.
