Abstract

In this study, effect of make-up and recirculating flow on the efficiency of carbonateor reactor was investigated using a comprehensive model based on experimental data obtained from a fluidized bed reactor under harsh condition and in the presence and absence of sulfur dioxide. Results obtained from applying comprehensive model to the experimental data showed that in the both reaction conditions, maximum absolute error between experimental data and those predicted by model was 2.5% and 1.8%, respectively. Also under both reaction conditions, effect of make-up flow on the efficiency of carbonator reactor was higher than that of recirculating flow and in the presence of sulfur dioxide, efficiency of carbonator reactor more increased with increasing the make-up flow. Furthermore, the presence of sulfur dioxide and the sulfation reactions occurrence led to a requirement of make-up flow 36.5 times higher in order to achieve the same efficiency as in the absence of sulfur dioxide.
