In this paper, The gas hydrocarbon solvent is used more and more in heavy oil recovery, because in some recycling conditions, the gas hydrocarbon solvent has many advantages over the heating method. In the process of recovery, the injection of an easily mixed solvent means a mass transfer process that is affected by the diffusion coefficient. Therefore, the measurement of diffusivity is very important. However, such words pose a huge challenge to experiment and data analysis. Although the diffusion coefficient is important, the diffusion coefficient of the vapor-liquid that is understood and calculated is not very significant. In a recent study, guerrero Aconcha Kantzas (2008) used slope and intercept analysis techniques to successfully obtain the diffusion coefficient of the heavy oil of liquid hydrocarbons. However, the technique involves the knowledge of prior composition concentration. There is a non-iterative, finite volume method that can obtain the diffusion coefficient without the need for concentration density. Computed auxiliary to
