Carbonator

← Previous | Next →

Inputs for the performance of the chemical looping system's carbonator are entered on the Carbonator parameter screen. The following parameters are provided:

•Carbonator Temperature: This is the carbonator reactor temperature.

•Degree of Carbonation: This is the ratio of the loading difference in the carbonator to the maximum loading difference.

•Makeup Limestone/Recirculating Sorbent: This is the ratio of makeup sorbent to recirculating sorbent.

•Maximum CaO Conversion: This is the maximum possible fraction of CaO converted to CaCO3 in the carbonator.

•Actual CaO Conversion: This is the actual fraction of CaO converted to CaCO3 in the carbonator.

•Residence Time of Solids: This is the residence time of solids in the carbonator.

•Gas Phase Pressure Drop: This is the pressure drop of flue gas in the carbonator. The flue gas has to be pressurized to overcome this pressure drop, so as to maintain the gas-flow in the CO2 removal system.

•ID Fan Efficiency: This is the efficiency of the fan used to raise the flue gas pressure.

•Makeup Sorbent Temperature: This is the temperature of the makeup sorbent.
