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.

强化分离含有二氧化碳的等温三元气体混合物

实验研究了加强分离含有二氧化碳的等温三元气体混合物的可能性。结果表明，二氧化碳的优先转移要求系统最初是扩散不稳定的，并且混合组分的相互扩散系数可以彼此显着不同或值接近。对平坦的垂直通道和有限高度的圆柱形通道的含二氧化碳的等温三元气体混合物的稳定性进行了线性分析。数值研究的结果与实验数据的比较显示了定性的一致性。
