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.
