WebAlthough FEM is rarely used for the simulation of fixed-bed reactors – to the authors knowledge, within the last decade, only Motlagh and Hashemabadi (2008) used the method for the simulation of fluid dynamic and heat transfer study of a very small packed bed (N=2) containing 10 cylindrical particles – a brief introduction of that method will be given. WebExperiments of heat and mass transfer from the tube wall to the fluids flowing through the packed beds were carried out separately. In heat transfer air was used as the …

WebThe liberated CO2 is removed from the reactor to external storage. In the exothermic carbonation step, a CO2-containing gas flows through a bed of CaO particles in the reaction zone, forming CaCO3, while CO2-depleted gas leaves the system. The reactor design is refined using a numerical heat and fluid flow model for the calcination step.
