An environmentfriendly process for limestone calcination

Dec 10 2019 The limestone calcination occurs in pure CO 2 environment and the calcination temperature is around 900 C when CO 2 pressure P CO2 is at 1 atm. CaCO 3 decomposition is inhibited when P CO2 exceeds the CO 2 equilibrium pressure P CO2 eq and the inhibition can be solved by increase of temperature.
