Abstract

A process for sequestering carbon dioxide from the flue gas emitted from a combustion chamber is disclosed. In the process, a foam including a foaming agent and the flue gas is formed, and the foam is added to a mixture includi ng a cementitious material (e.g., fly ash) and water to form a foamed mixture. Thereafter, the foamed mixture is allowed to set, preferably to a controlled low- strength material having a compressive strength of 1200 psi or less. The carbon dioxide in the flue gas and waste heat reacts with hydration products in the controlled low-strength material to increase strength. In this process, the carbon dioxide is sequestered. The CLSM can be crushed or pelletized to form a lightweight aggregate with properties similar to the naturally occurring mineral, pumice.

Claims (20)

1. A process for preparing a controlled low-strength material having a compressive strength of 1200 psi or less, the process comprising:
preparing a mixture including water and a cementitious material;
recovering flue gas from a combustion chamber;
forming a foam including a foaming agent and the flue gas;
mixing the foam into the mixture to form a foamed mixture; and thereafter allowing the foamed mixture to set to form the controlled low-strength material.
2. The process of claim 1 wherein:
coal is combusted in the combustion chamber.
3. The process of claim 1 wherein:
the flue gas includes carbon dioxide.
4. The process of claim 3 wherein:
during the step of allowing the foamed mixture to set, the carbon dioxide in the flue gas reacts with hydration products in the controlled low-strength material to sequester carbon dioxide.
5. The process of claim 1 wherein:
the controlled low-strength material has a compressive strength of 300 psi or less.
6. The process of claim 1 further comprising:
shaping the foamed mixture into aggregates before allowing the foamed mixture to set.
7. The process of claim 1 further comprising:
subjecting the foamed mixture to a shaping process selected from pelletizing, extruding and briquetting before allowing the foamed mixture to set.
8. The process of claim 1 further comprising:
crushing the controlled low-strength material after the controlled low-strength material has set.
9. The process of claim 8 further comprising:
separating the crushed controlled low-strength material into different particle size fractions.
10. The process of claim 1 wherein:
the step of allowing the foamed mixture to set includes passing a heated fluid through crushed or pelletized foamed mixture.

the cementitious material is fly ash.
12. The process of claim 11 wherein:
the foamed mixture includes 700 to 1700 pounds of fly ash per cubic yard of the foamed mixture and 100 to 900 pounds of water per cubic yard of the foamed mixture.
13. The process of claim 11 wherein:

14. The process of claim 13 wherein:
the foamed mixture includes 1 to 100 cubic feet of foam per cubic yard of the foamed mixture.
15. The process of claim 11 wherein:
the fly ash is ASTM Class C fly ash.
16. A process for sequestering carbon dioxide from flue gas emitted from a combustion chamber, the process comprising:
forming a foam including a foaming agent and the flue gas;
mixing the foam with a mixture including a cementitious material to form a foamed mixture; and allowing the foamed mixture to set.
17. The process of claim 16 wherein:
the mixture sets to a controlled low-strength material having a compressive strength of 1200 psi or less.
18. The process of claim 16 wherein:
the mixture includes water, and the cementitious material is fly ash.
19. The process of claim 18 wherein:
the fly ash is recovered from flue gas emitted from the combustion chamber.
20. A process for sequestering carbon dioxide from a gas including one weight percent or more carbon dioxide, the process comprising:
forming a foam including a foaming agent and the gas;
mixing the foam with a mixture including water and fly ash to form a foamed mixture; and allowing the foamed mixture to set to a controlled low-strength material having a compressive strength of 1200 psi or less.
