Carbonate Looping is a promising option for the capture of CO2 from power plant flue gases. The Carbonate Looping process is carried out in a Dual Fluidized Bed (DFB) system with continuous looping of CaO, which is the CO2 carrier, between the two beds. The system consists of a carbonator, where CO2 is absorbed by CaO, operating at 600- 700 C and a regenerator operating at temperatures above 900 C. Experiments was carried out in a 10 kW DFB facility so as to investigate critical parameters affecting the CO2 capture efficiency of the process which are the CaO looping rate, the carbonator space time and the carbonator temperature. The rate of sorbent attrition was found to be 2% wt./h and is below the required sorbent make-up rate. Steady state CO2 capture efficiencies of 90% are demonstrated under realistic process conditions.
