Title:
METHOD AND APPARATUS FOR TREATMENT OF UNBURNTS
Document Type and Number:
WIPO Patent Application WO/2013/144884
Kind Code:
A3
Abstract:
A method and apparatus for treatment of unburnts in a flue stream 9 of a chemical looping combustion system. Unburnts present in the flue stream 9 are treated after CO2 is removed from the flue stream in a gas processing unit 13. As shown in Fig. 2, oxidation of the unburnts occurs primarily in an air reactor 2 in the presence of air 1, allowing the system to maintain CO2 capture effectiveness and removing the need for creation of enriched or pure oxygen 11.
