Abstract
A system for reducing carbon dioxide emissions from a flue gas generated via combusting a fossil fuel is provided. The system includes a carbonator and a classifier. The carbonator is configured to receive the flue gas and carbon absorbing particles. The classifier is fluidly connected to the carbonator and configured to receive a mixture that includes heat-transferring particles and the carbon absorbing particles. The mixture is fluidized within the classifier via the flue gas at a velocity such that the flue gas entrains and transports the carbon absorbing particles to the carbonator while the heat-transferring particles are not entrained nor transported to the carbonator.
Claims10
A method for reducing carbon dioxide emissions from a flue gas generated via combusting a fossil fuel, the method comprising:
- fluidizing a mixture that includes heat-transferring particles and carbon absorbing particles within a classifier via the flue gas at a velocity such that the flue gas entrains and transports the carbon absorbing particles to a carbonator fluidly connected to the classifier while the heat-transferring particles are not entrained nor transported to the carbonator.
The method of 1, wherein the heat-transferring particles are inert.
A method for reducing carbon dioxide emissions from a flue gas generated via combusting a fossil fuel, the method comprising:
- fluidizing a mixture that includes heat-transferring particles and carbon absorbing particles via a classification gas in a first fluidized bed or contacting chamber of a classifier at a first velocity that entrains and transports some of the carbon absorbing particles to a carbonator fluidly connected to the classifier such that the remaining mixture flows to a second fluidized bed or contacting chamber of the classifier;
- and
- fluidizing the remaining mixture via the classification gas in the second fluidized bed or contacting chamber at a second velocity that is greater than the first velocity and entrains and transports some of the carbon absorbing particles to the carbonator.
