High solids flux circulating carbonation reactor

1. 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 (MeCO 3 ) rich solids stream and a flue gas stream depleted in CO 2 , and

forward the flue gas stream depleted in CO 2 and the MeCO 3 rich solids stream to the separation device;

the separation device is configured to separate the flue gas steam depleted in CO 2 from the MeCO 3 rich solids stream and forward the MeCO 3 rich solids stream to the splitting device; and

the splitting device is configured to separate the MeCO 3 rich solids stream into at least a first MeCO 3 rich solids stream and a second MeCO 3 rich solids stream;

at least one pipe for providing the at least a first MeCO 3 rich solids stream to the fluidized bed heat exchanger to form at least a first cooled MeCO 3 rich solids stream and a second cooled MeCO 3 rich solids stream;

at least one pipe for providing the at least a first cooled MeCO 3 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 MeCO 3 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 MeCO 3 rich solids stream to the CFB carbonation reactor at a third location separate from the first and second locations.

2. The system according to claim 1 , wherein the CFB carbonation reactor is configured to receive the at least a first cooled MeCO 3 rich solids stream at a bottom region of the CFB carbonation reactor.

3. The system according to claim 1 , wherein the CFB carbonation reactor is configured to receive the at least a first cooled MeCO 3 rich solids stream at an intermediate region of the CFB carbonation reactor.

4. The system according to claim 1 , wherein the splitting device is configured to separate the MeCO 3 rich solids stream into at least a third MeCO 3 rich solids stream.

5. The system according to claim 4 , further comprising at least one pipe for providing the at least a third MeCO 3 rich solids stream to a calcination system to form a MeO rich solids stream.

6. The system according to claim 5 , further comprising at least one pipe for providing the MeO rich solids stream to the CFB carbonation reactor.

7. The system of claim 6 , further comprising at least a heat exchanger configured to cool the MeO rich solids stream prior to being provided to the CFB carbonation reactor.

8. The system according to claim 1 , wherein the separation device is located external to the CFB carbonation reactor.

9. The system according to claim 1 , wherein the separation device is located internal to the CFB carbonation reactor.
