Abstract The solubilities and diffusion coefficients of crude oils having API° ranging from 11 to 28 have been measured in distilled and saline water of 44 g L−1 NaCl at temperatures 25, 35, and 45 °C. A linear relationship was observed between the maximum oil solubilities in distilled water and those in saline water for all the crudes over the range of temperature studied. The Setschenow salting-out parameter was found to be 0.125 independent of temperature and API°. Such a parameter is valuable in estimating the crude oil solubilities in waters of different salinity. An analytical solution for unsteady-state diffusion was done using Fourier series. A linear relationship was found between the diffusion coefficients of oils in distilled water and those in saline water. Observed data for diffusion coefficients of the oils have been correlated in terms of API°, temperature and ionic strength with an average absolute deviation of 2%.
