An empirical correlation given by
D12/T=1.013×10-14η-0.9222
is proposed for predicting binary/pseudo binary diffusion coefficients of carbon dioxide in water and in aqueous electrolytic solutions, where D12 is diffusion coefficient [m2/s], T is temperature [K], and ηis viscosity [Pa s].The average absolute deviation AAD for this correlation is 5.6% for the literature data on D12 of CO2 in water with number of data points N of 79 and 3.9% (N=103) for those in aqueous electrolytic solutions. The above correlation obtained in this study is more accurate than the various empirical correlations proposed in the literature.
