Abstract
This study developed a simple model to investigate effects of important operating parameters on performance of a bubbling-bed adsorber and regenerator system collecting $CO_2$ from flue gas. The chemical reaction rate was used with mean particles residence time of a reactor to determine the extent of conversion in both adsorber and regenerator reactors. Effects of process parameters - temperature, gas velocity, solid circulation rate, moisture content of feed gas - on $CO_2$ capture efficiency were investigated in a laboratory scale process. The $CO_2$ capture efficiency decreased with increasing temperature or gas velocity of the adsorber. However, it increased with increasing the moisture content of the flue gas or the regenerator temperature. The calculated $CO_2$ capture efficiency agreed to the measured value reasonably well. However the present model did not agree well to the effect of the solid circulation rate on $CO_2$ capture efficiency. Better understanding on contact efficiency between gas and particles was needed to interpret the effect properly.
