A study of turbulent mass transfer in a wetted-wall column

<p>"The field of mass transfer is one of great interest to the chemical engineer. An understanding of this field is vital in the design of many types of chemical processing equipment, particularly in the areas of distillation, extraction, absorption, adsorption, and reactor analysis and design.</p> <p>However, much of the knowledge in this area at the present time is in the form of empirical relationships, and the basic theory is still not well delineated. This lack of understanding leads to expensive and over-sized or under-sized equipment.</p> <p>A particular area within this field which needs additional investigation is the theory of mass diffusion. Many theories have been proposed and some have been used with limited success, but no present theory adequately represents the actual diffusion phenomenon.</p> <p>The purpose of this investigation was to study the phenomenon of mass diffusion through the use of a wetted-wall column. This investigation entailed: (1) the design and construction of a wetted-wall column, (2) the development of a method to experimentally measure local mass transfer, (3) the actual measurement of momentum and mass transfer data through the use of the wetted-wall column, and (4) the calculation and correlation of mass eddy diffusivities in a wetted-wall column operating with a liquid-gas system"--Introduction, pages 1-2.</p>
