Abstract
The mixing of carbon dioxide dissolved in multicomponent gas mixtures at various pressures was studied. It was found that at a certain pressure the diffusion separation of components is violated and structured flows arise in the system. The pressure regions are fixed at which the conditions of priority transfer of the component with the highest molecular weight in the mixture are realized in the system. To analyze the effect of pressure on the process of changing the diffusion – convection modes, a mathematical model has been proposed that takes into account the kinetic features of multicomponent mixing. It is shown that the change in mass transfer modes is associated with a significant difference in the diffusion abilities of the components.
