The design of this equipment is different from the previous experience of calcium looping cycle for carbon capture. The use of fluidized beds and large particles are not feasible for this novel application of calcium looping. New reactors and different arrangements for the carbonation process are necessary. The design of a carbonator reactor for a specific Calcium Looping-Concentrated Solar Power application has not been addressed yet in detail in literature. In this work, a comparison of single stage reactor, two parallel reactors and two reactors in series with intercooling are simulated to calculate conversion rates, gas temperatures and flow rates, and heat transfer rates to the external cooling fluid. The modelling encompasses fluid dynamics, lime conversion kinetics and heat transfer, which are solved using a 1-D discrete mesh. The third arrangement results in the most reasonable sizes, and larger conversion rates, avoiding the occurrence of internal reactor zones in which the reaction is inhibited. Energy balance components are also quantified for each configuration. info:eu-repo/grantAgreement/ES/DGA/T46-17R info:eu-repo/grantAgreement/EC/H2020/727348/EU/SOlar Calcium-looping integRAtion for Thermo-Chemical Energy Storage/SOCRATCES This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 727348-SOCRATCES info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.295 2020 ENGINEERING, MECHANICAL 14 / 133 = 0.105 2020 Q1 T1 THERMODYNAMICS 6 / 60 = 0.1 2020 Q1 T1 MECHANICS 13 / 135 = 0.096 2020 Q1 T1 ENERGY & FUELS 41 / 114 = 0.36 2020 Q2 T2 1.714 2020 Industrial and Manufacturing Engineering 2020 Q1 Energy Engineering and Power Technology 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Lisbona, Pilar Romeo, Luis M.
