Experimental and numerical study of the peculiarities of the multicomponent gas mixtures separation under natural gravity convection

Experimental study of the features of separation process in ternary gas mixtures 0.6179 H₂ + 0.3821 N₂ – CH₄ and 0.7760 CH₄ + 0.2240 R12 – n-C₄H₁₀ is conducted. Conditions of the priority transfer of the density heaviest component of the mixture are discussed. The problem is solved by the splitting scheme by physical parameters. Numerical data on the time evolution of components concentrations at different concentrations of components of the initial mixture are obtained. Calculations have shown that for ternary systems the concentration increase of the heaviest component results to the intensity growth of convective mixing. (paper)
