Abstract：By comparative study of mass transfer characteristics of high and low concentration H2S absorption, the volumetric overall mass transfer coefficient (KGa) for high and low concentration H2S removal from flue gas into aqueous solution of carbonate solution in a packing column was investigated. The KGa value was evaluated over ranges of liquid load, concentration of absorbent and gas flow by response surface methodological analysis based on Box-Behnken design. Two quadratic response surface models were respectively built for high and low concentration H2S absorption. The models demonstrated that the regularity of three impact factors on KGa were consistent. The liquid load was synergistic with concentration of absorbent. For 720 L/h low concentration H2S (2.16%, j), the maximum value of KGa was achieved when the liquid load was 11.28 L/h and concentration of absorbent 0.082 mol/L. For 720 L/h high concentration H2S (20.1%, j), the maximum value of KGa was achieved when the liquid load was 11.28 L/h and concentration of absorbents 0.764 mol/L.
