INTERPHASE MASS TRANSFER BETWEEN LIQUID-LIQUID COUNTER-CURRENT FLOWS. II. MASS TRANSFER KINETICS
A theoretical analysis of mass transfer kinetics based on the similarity variables method for a liquid-liquid counter-current flow has been made. The obtained numerical results 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 counter-current one are shown. 1)University of Veszprém, Research Institute Chemical Process Engineering, 8201 Veszprém, P.O.B. 125, Hungary; 2)Bulgarian Academy of Sciences, Institute of Chemical Engineering, 1113 Sofia, Acad.
