Introduction to the surface renewal model of mass transfer for the analysis and design of gas-liquid contacting equipment and membrane filters
Applications of the Surface Renewal Model of Mass Transfer provides a rigorous application of the surface renewal theory of mass transfer to describe physical and chemical gas absorption and membrane filtration. This book demonstrates that the surface renewal model can predict the experimentally measured liquid-side physical mass-transfer coefficient in gas absorption with a fair degree of accuracy, shows that the surface renewal model can correlate permeate flux and transmembrane pressure drop data in constant pressure and constant flux microfiltration, and contains numerous examples of the application of the model to real-world situations.
This book includes information on:
* Applications of the surface renewal model in fields like chemical engineering and oceanography
* The complex nature of the surface renewal model as a better description of the turbulent hydrodynamics that prevail at the gas-liquid interface compared to the film model
* Measurements of the liquid-side physical mass-transfer coefficient in gas absorption studies and surface-age distributions in wind-wave tanks
* Flow instabilities induced by wall roughness or spacers or by their deliberate introduction into the main flow in membrane filtration
* Analysis and design of gas-liquid contactors (stirred tanks and packed towers) and membrane filters using a mass-transfer approach
Applications of the Surface Renewal Model of Mass Transfer is an excellent, first-of-its-kind reference for researchers in academia and industry, along with advanced students in chemical engineering, environmental engineering, bioprocess/biological engineering, paper engineering, and related programs of study.
