Abstract

A theoretical analysis of mass-transfer kinetics based on the method of similarity variables for a liquid-liquid counter-current flow has been made. The numerical results obtained for the mass-transfer rate (Sherwood number) in the case of a laminar boundary layer with a flat interphase are compared with analogous results for a co-current flow. The ratio between the mass-transfer rate and the energy dissipation in the boundary layer is determined. The advantages of the co-current flow due to lower energy losses compared with the case of the counter-current one are shown.
