ABSTRACT

In this study, two-dimensional computational fluid dynamics (CFD) simulations of carbon dioxide (CO₂) adsorption and regeneration processes in a circulating fluidized bed were investigated. Potassium carbonate (K₂CO₃) was used as solid sorbent particles. The results were validated with the released outlet CO₂ mass fraction and the differential pressure based on a laboratory scale circulating fluidized bed. Three different reaction models including homogeneous model, deactivation model and equilibrium model were examined in order to validate the simulated CO₂ adsorption performance. The results showed that the simulated data obtained from equilibrium model was found to be well correspondence with the experimental results. Thus, the equilibrium model was then applied in the CO₂ desorption processes. To determine the significance of main operating parameter factors on a considered response, the central composite design (CCD) approach was used. The four factors of gas inlet velocity, solid circulation rate, temperature and water vapor content were selected as the independent factors for CO₂ adsorption. The results showed that solid circulation rate and temperature were the two significant operating factors affecting the CO₂ removal performance. Additionally, three factors, which were temperature, gas inlet velocity and solid circulation rate, were selected as independent factors on the desorbed CO₂ mass fraction in the downer reactor. The simulated results showed that the most significant operating factors on the CO₂ desorbed was gas inlet velocity. Consequently, the suitable operating conditions were proposed through the response surface method for both the CO₂ adsorption and solid sorbent regeneration.

Keywords: CFD simulation; CO2 capture; Circulating fluidized bed; Statistical experimental design.
