An experimental and analytical investigation was made into the absorption of CO_2 from concurrently flowing CO_2-laden air into thin water film flow, with the focus on establishing the method of prediction of the average mass transfer coefficient, α_<DL>. We proposed an analytical model to calculate mass transfer rate, and verified that α_<DL> could be predicted with an accuracy of ±30%. Introducing a new Parameter (≡α_<DL>/j_L, where j_L is the superficial velocity of liquid phase) which is useful for taking the efficiency of the liquid used into consideration, we have obtained a working formula by which we can calculate α_<DL> using only the flow conditions of both gas and liquid phases. By using that correlation α_<DL> could be predicted with an accuracy of ±40%.
