MODELLING A CLC PROCESS IMPROVED BY CLOU AND VALIDATION IN A 120 kW UNIT
To optimize a CLC process and to make predictions about the system performance over different operating conditions, a model of the whole system is necessary.In this work a detailed fluid dynamic and kinetic model is developed for both the air and fuel reactors to obtain a global simulation tool of the core of a CLC unit.The CLC model is validated against experimental results obtained in a 120 kWth CLC unit burning natural gas and using as oxygen carrier a CaMnO3-type perovskite.A good agreement between experimental and model predictions of fuel and solid conversions was found when temperature, pressure drop, solids circulation rate and gas flows in both air and fuel reactor have been varied.Model predictions showed that complete combustion can be reached at operation conditions where the Chemical Looping with Oxygen Uncoupling (CLOU) effect of the oxygen carrier becomes dominant.The validated model is a powerful tool to simulate and optimize the CLC process.
