Abstract
Agitated vessels are used widely in chemical engineering practice to effect processes such as liquid-liquid extraction, dissolution and crystallization of salts, ore leaching, mixing, chemical and biochemical reactions, etc. One of the most important design parameters of agitated vessels is the heat and mass transfer coefficients from the wall of the vessel to the agitated solution. By far, cylindrical agitated vessels have received most of the attention in heat and mass transfer studies, scant attention was given to other geometries of agitated vessels such as the rectangular geometry which is used frequently in practice. The object of the present work is to study the rate of mass transfer between agitated solutions and the walls of rectangular vessels. The study of mass transfer from the vessel wall to the agitated solution is essential for predicting the rate of diffusion controlled processes which might take place at the vessel wall e.g biochemical reactions taking place at a layer of immobilized enzyme fixed to the wall of the agitated vessel, electrochemical reactions taking place at an electrode fixed to the wall of the vessel. Besides, the present work is of importance to designing batch dialyzers involving two rectangular compartments divided by a membrane. The present work is also useful for predicting the rate of diffusion controlled corrosion of rectangular agitated vessels.
