The results of research on hydrocarbon mixture sorption in porous medium showed that adsorbent activity with regard to separate components of a gas mixture changes in partial dependence on pressure. The alteration of vented gas content will take place not only in gas condensate fields, when this effect is conditioned by the losses of condensate in the stratum, but also in gas fields, by methods connected with desorption processes. At the same time, gas composition is the basis for different process calculations, such as separation, gas transport, gas filtration in porous medium, and others. Thus the determination of characteristic alterations of gas mixture composition in thermodynamically nonequilibrium hydrocarbon systems mass transfer process becomes important. The binary (methane + pentane) and tricomponent (methane + butane + pentane) systems composed of individual gases of high purity have been researched. Then with help of mathematical methods of experimental data processing the moment of the more characteristic changes of the mass transfer process was discovered. Processing of experimental data for tricomponent system by statistical differentiation allowed the discovery of a pressure below of which lightening of the vented gas was observed.
