Interphase Mass Transfer- An Important Mass Transfer Phenomenon

Abstract

Various theories were proposed in past to explain interphase mass transfer. For the case of gas liquid interphase mass transfer, it is well known fact that for every concentration in one phase, there is equilibrium concentration in other phase. The departure from this equilibrium state is causing the mass transfer. Wetted wall column experiments were considered for understanding of two resistance concepts [1,2]. Theories namely Film theory, penetration theory and surface renewal theory were proposed by various investigator to explain the interphase mass transfer and relation between diffusivity and mass transfer coefficient. Interphase mass transfer has been interesting area of investigation because of its complexity and importance in mass transfer in many processes[3,4].
