Abstract
A system for reducing carbon dioxide emissions from a flue gas is provided. The system includes a carbonator, and a calciner. The carbonator receives the flue gas and lean sorbent particles such that the lean sorbent particles absorb gaseous carbon dioxide from the flue gas and become loaded sorbent particles. The calciner includes a drum that defines a cavity having a first opening and a second opening. The first opening is fluidly connected to the carbonator such that the loaded sorbent particles flow into the cavity from the carbonator. The drum rotates such that at least some of the loaded sorbent particles are mixed with heat-transferring particles so as to release the absorbed gaseous carbon dioxide and exit the drum via the second opening as lean sorbent particles.
