The Oxy-CaL process: A novel CO2 capture system by integrating partial oxy-combustion with the Calcium-Looping process 2017 Access copy available to the general public Unrestricted This paper proposes a novel CO2 capture technology from the integration of partial oxy-combustion and the Calcium-Looping capture process based on the multicycle carbonation/calcination of limestone derived CaO. The concentration of CO2 in the carbonator reactor is increased by means of partial oxy-combustion, which enhances the multicycle CaO conversion according to thermogravimetric analysis results carried out in our work, thus improving the CO2 capture efficiency. On the other hand, energy consumption for partial oxy-combustion is substantially reduced as compared to total oxy-combustion. All in all, process simulations indicate that the integration of both processes has potential advantages mainly regarding power plant flexibility whereas the overall energy penalty is not increased. Thus, the resulting energy consumption per kilogram of CO2 avoided is kept smaller than 4 MJ/kg CO2, which remains below the typical values reported for total oxy-combustion and amine based CO2 capture systems whereas CO2 capture efficiency is enhanced in comparison with the Calcium-Looping process. info:eu-repo/grantAgreement/ES/MINECO/CTQ2014-52763-C2-1-R info:eu-repo/grantAgreement/ES/MINECO/CTQ2014-52763-C2-2-R info:eu-repo/grantAgreement/ES/MINECO/MAT2013-41233-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 7.9 2017 ENGINEERING, CHEMICAL 4 / 137 = 0.029 2017 Q1 T1 ENERGY & FUELS 8 / 97 = 0.082 2017 Q1 T1 3.162 2017 Building and Construction 2017 Q1 Civil and Structural Engineering 2017 Q1 Energy (miscellaneous) 2017 Q1 Nuclear Energy and Engineering 2017 Q1 Fuel Technology 2017 Q1 Management, Monitoring, Policy and Law 2017 Q1 Mechanical Engineering 2017 Q1 Energy Engineering and Power Technology 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Valverde, J.
