CALCULATION OF DIFFUSIVE PROCESSES FOR SOME NATURAL HYDROCARBONIC GAS MIXTURES INTO AIR

Abstract

The analysis of diffusive processes for five natural hydrocarbonic gaseous mixtures into air at T = 298,0 K and P = 0,101 MPa is carried out. The effective diffusion coefficients and matrix coefficients of multicomponent diffusion are defined. Advantages of effective coefficients application for the mass transfer description are shown. The calculated diffusion coefficients can be used as the reference data.
