Analytically, on the basis of the differential equations of material balance, the equations of working lines and mass transfer in the distillation column for binary mixtures for the strengthening and exhaustive parts of the packed distillation column with a diffusion structure of the flow in a continuous liquid phase are derived. Comparative examples of the calculation for typical structures of the flow of ideal displacement are given using the derived equations that take into account the longitudinal diffusion for a “ethanol–ethyl alcohol” binary mixture. A calculation algorithm is proposed, and technological and geometrical parameters are compared with similar parameters of the same column and are calculated according to a typical algorithm, when the dispersed gas phase has the structure of an ideal displacement flow, and the continuous liquid phase is an ideal mixing. The scheme of material flows and their concentrations is presented in the exhaustive part of the rectification column taking into account the longitudinal diffusion.
