Abstract The possibility of intensifying the separation of isothermal ternary gas mixtures containing carbon dioxide was studied experimentally. It was shown that the preferential transfer of carbon dioxide requires the system to be initially diffusively unstable, and the interdiffusion coefficients of mixing components can either differ significantly from each other or be close in value. A linear analysis of the stability of isothermal ternary gas mixtures containing carbon dioxide for a flat vertical channel and a cylindrical channel of finite height was performed. Comparison of the results of the numerical study with experimental data showed qualitative coherency.
