Simultaneous removal efficiency of H2S and CO2 by high-gravity rotating packed bed: Experiments and simulation

This study explores the possibility of applying high-gravity rotating packed bed (HGRPB) in removing H2S and CO2 from biogas. Ca(OH)2 aqueous solution was used as the absorbent in this study. Different experimental conditions including solution pH, rotating speed (R S) of HGRPB, gas f...
