Abstract
A method for recapturing sulfur in a chemical looping system includes receiving a flue gas stream containing a sulfur-containing species, reducing a temperature of the flue gas stream, introducing a calcium-based makeup material to the reduced temperature flue gas stream, capturing the sulfur-containing species from the reduced temperature flue gas stream, and recycling the sulfur-containing species to a reducer of the chemical looping system.
