This study compares the carbon dioxide capture efficiency of packed bed (PB) column and rotating packed bed (RPB) absorber by mono-ethanolamine (MEA) solution. Carbon dioxide absorption experiments were carried out in laboratory scale packed bed column and rotating packed bed at various lean carbon dioxide loadings of the MEA solution They were modelled successfully by an ASPEN Plus advanced customer model (ACM). Using these models, we found that substantial savings of packing volume can be achieved using a series arrangement of RPB and PB for the CO2 capture process using 30wt% MEA solution.
