  • A carbonate looping using twin fluidized bed was established.
  • A 350MWth coal-fired power plant was used as an upstream plant.
  • High CO2 capture rate (above 90%) was achieved.
  • The optimization parameters were obtained through sensitivity analysis.




CO2 as the major greenhouse gas plays an important role in environmental problems. Therefore, it is reasonable to find an effective technology for mitigating large CO2 emissions. Carbonating looping is an efficient post-combustion CO2 capture technology using limestone sorbent, which is more energy-saving than traditional technologies. In our research, a carbonate looping process model had been developed using ASPEN PLUS software. In detail, the sensitivity analysis of main parameters were adopted. The simulation results indicated that the CO2 capture rate of the whole process can achieve above 90% and CO2 concentration in the decarbonated flue gas was less than 4% under the carbonation temperature, the calcination temperature, the F0/FCO2 and the gas-solid separation were 630°C, 900°C, 0.04, 1.0, separately. This work gave an potential example for the retrofitting current coal-fired power plant combined with carbonate looping process.

Keywords: CO2 capture; Carbonate looping; Process model; Twin Fluidized bed; Sensitivity analysis.
