A model was established to predict the overall volumetric mass-transfer coefficients (KGa) of CO2 and NH3 with reactions in the RPB at gravity levels of about 70−250g. Experiments involving the simultaneous absorption of CO2 and NH3 into water in an RPB were carried out under different conditions, and it was found that KGa increased with increasing rotation speed, liquid volumetric flow rate, gas volumetric flow rate, and NH3/CO2 molar ratio. It was observed that the model was in good agreement with the experimental data, with deviations within 10% compared to the experimental values.
