Abstract

The calculation of diffusion processes for some natural hydrocarbon gas mixtures in the air at the temperature range of 273-1000 K and P = 0.101 Mpa.The effective diffusion coefficients (ECD) and the matrix of multicomponent diffusion coefficients.The advantages of the use of effective mass transfer coefficients in the description. The temperature dependences of the effective diffusion coefficients for two, three – component gas systems. The publications related to the determination of the temperature dependence of gas in multicomponent mixtures, repeatedly noted that the effect of the concentration of the component is very poorly reflected in the exponent of the temperature dependence of the component. The calculated coefficients can be used as reference data.
