Methods of nonequilibrium thermodynamics for studying and simulating mass transfer processes in liquid-liquid systems

A mass transfer model in which the generalized thermodynamic force accounting for colloidal and chemical phenomena in the interfacial zone, such as the formation of disperse interfacial layers and films, is taken to be the driving force is considered. A method for calculating the difference between the pressures in the film and in the phase, the interfacial-film thicknesses, and mass transfer coefficients is proposed. It is found that the resistance to mass transfer in porous films varies with time, passing through a maximum.
