Résumé: A theoretical analysis of gas-liquid counter-current flow in laminar boundary layers with flat phase boundary based on similarity variables method has been done. The obtained numerical results for the energy dissipation, mass transfer rate and their ratioare compared with analogous results for co- current flows. A diffusion type of model is proposed for modeling of the mass transfer with chemical reaction in the column apparatusesin the cases of circulation zones. The presence ofrising and descending flows (the change of the velocity direction) leads to using three coordinate systems. An iterative algorithm for the concentration distribution calculation is proposed. The influence of the zones breadths on the mass transfer efficiency in the column is investigated.
