Abstract	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 flow rate (Q _G), and liquid flow rate (Q _L) were investigated with respect to the removal efficiency (E) of H₂S and CO₂. The experimental and simulated results show that the optimal removal efficiency of H₂S and CO₂ using HGRPB achieved nearly the same as 99.38 and 99.56% for removal efficiency of H₂S and 77.28 and 77.86% for removal efficiency of CO₂, respectively. Such efficiencies corresponded with the following optimal conditions: a solution pH of 12.26, HGRPB reactor with the rotating speed of 1,200 rpm, the gas flow rate of 2.46 (L/min), and the liquid flow rate of 0.134 (L/min).
