Download or read book The Baseline Mass Transfer Coefficient written by Johnny Lee and published by Cambridge Scholars Publishing. This book was released on 2019-12-13 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of a Standard Specific Baseline Mass Transfer Coefficient (KLa0)20 represents a revolutionary change in the understanding, designing, operation and maintenance of aeration equipment, as well as providing a baseline for future research and development for water and wastewater treatment systems. Previously, it has not been possible to correlate mass transfer coefficients (KLa) from one test to another, even under ordinary testing circumstances. This book discusses the use of the Standard Model to determine the baseline for any test, and its major finding is showing that gas transfer is a consistent relativistic theory of molecular interactions based on the Standard Model. Previously, the primary challenge was the appearance of divergences in the mass transfer coefficient calculations and estimations. This procedure of renormalization to a baseline is a great achievement in physics and engineering.

Book excerpt: The book is about the discovery of a Standard Specific Baseline Mass Transfer Coefficient (KLa0)20 that represents a revolutionary change in the understanding, designing, and operation of aeration equipment, as well as providing a baseline for future research and development for water and wastewater treatment systems. It discusses the use of the Standard Model for oxygen transfer to determine the baseline, and its major finding is to show that the gas transfer model is a consistent relativistic theory of molecular interactions. Previously, the challenge was the appearance of divergences in the mass transfer coefficient estimations that defies aeration design. This normalization to a baseline is a great achievement in physics and engineering.
Download or read book Mass Transport in Solids and Fluids written by David S. Wilkinson and published by Cambridge University Press. This book was released on 2000-11-02 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of matter transport is central to understanding the processing of materials and their subsequent mechanical properties. While thermodynamics determines the final state of a material system, it is the kinetics of mass transport that governs how it gets there. This book, first published in 2000, gives a solid grounding in the principles of matter transport and their application to a range of engineering problems. The author develops a unified treatment of mass transport applicable to both solids and liquids. Traditionally matter transport in fluids is considered as an extension of heat transfer and can appear to have little relationship to diffusion in solids. This unified approach clearly makes the connection between these important fields. This book is aimed at advanced undergraduate and beginning graduate students of materials science and engineering and related disciplines. It contains numerous worked examples and unsolved problems. The material can be covered in a one semester course.

Download or read book Mass Transfer and Absorbers written by T. Hobler and published by Elsevier. This book was released on 2013-10-22 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass Transfer and Absorbers deals with absorption and mass transfer processes and the factors to consider in designing absorbers. Calculations are supported by a uniform, generalized process driving force, complying with Maxwell's equation, and the coefficients are made as independent as possible in terms of the kind of diffusion and of the values of the concentrations. This volume is comprised of seven chapters and begins with an overview of the general principles of diffusional mass transfer, absorption and stripping, and equilibrium between gas and liquid phases. Steady-state mass transfer by diffusion is then discussed, along with mass transfer in a single phase (forced flow and unforced flow). Subsequent chapters explore design considerations for mass transfer equipment and related problems; adsorption accompanied by a chemical reaction; and problems relating to hydrodynamics. The final chapter is devoted to some practical issues, including economic flow velocity and mechanical features of packed, plate, and spray tower designs. This book is intended for practicing designers and engineers.
Download or read book Introduction to Computational Mass Transfer written by Kuo-Tsung Yu and published by Springer. This book was released on 2016-09-26 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an easy-to-understand introduction to the computational mass transfer (CMT) method. On the basis of the contents of the first edition, this new edition is characterized by the following additional materials. It describes the successful application of this method to the simulation of the mass transfer process in a fluidized bed, as well as recent investigations and computing methods for predictions for the multi-component mass transfer process. It also demonstrates the general issues concerning computational methods for simulating the mass transfer of the rising bubble process. This new edition has been reorganized by moving the preparatory materials for Computational Fluid Dynamics (CFD) and Computational Heat Transfer into appendices, additions of new chapters, and including three new appendices on, respectively, generalized representation of the two-equation model for the CMT, derivation of the equilibrium distribution function in the lattice-Boltzmann method, and derivation of the Navier-Stokes equation using the lattice-Boltzmann model. This book is a valuable resource for researchers and graduate students in the fields of computational methodologies for the numerical simulation of fluid dynamics, mass and/or heat transfer involved in separation processes (distillation, absorption, extraction, adsorption etc.), chemical/biochemical reactions, and other related processes.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 2004, this book collects several up-to-date methods for quantitative analysis of biospecific interactions, a field that has a long history that perhaps can be said to have begun with the classical paper of G. Scatchard in 1949 (The attractions of proteins for small molecules and ions, but which has advanced impressively during the last few years. A precise spatial arrangement of just a few hydrogen bonds can confer a remarkably specific reversible association between two molecules. A web of weak interactions governs biospecific recognition in general. The binding equilibria in living cells tune and coordinate a multitude of functions. The thermodynamic properties of such interactions are often studied by binding experiments in simplified and essentially ideal systems. However, similar types of studies may elucidate the biologically relevant dynamic steady-state conditions in living cells and organisms, allowing for the very wide range of interactant concentrations and the interplay between the many reactions and interactions. The development in biosciences will continue with in-depth studies of macromolecules and membranes. More detailed knowledge will allow analyses of delicate balances between substances and events in the complex systems involved in life processes. Methods to study biospecific affinities are thus highly important tools for understanding mechanisms and effects of molecular binding events in vivo and in vitro, e.g., in biochemical, biomedical and pharmaceutical research, and for biotechnological research and production.

Download or read book Mass Transfer written by A. P. SINHA and published by PHI Learning Pvt. Ltd.. This book was released on 2012-05-09 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the fundamental principles of the mass transfer phenomenon and its diverse applications in process industry. It covers the full spectrum of techniques for chemical separations and extraction. Beginning with molecular diffusion in gases, liquids and solids within a single phase, the mechanism of inter-phase mass transfer is explained with the help of several theories. The separation operations are explained comprehensively in two distinct ways—stage-wise contact and continuous differential contact. The primary design requirements of gas–liquid equipment are discussed. The book provides a detailed discussion on all individual gas–liquid, liquid–liquid, solid–gas, and solid–liquid separation processes. The students are also exposed to the underlying principles of the membrane-based separation processes. The book is replete with real applications of separation processes and equipment. Problems are worked out in each chapter. Besides, problems with answers, short questions, multiple choice questions with answers are given at the end of each chapter. The text is intended for a course on mass transfer, transport and separation processes prescribed for the undergraduate and postgraduate students of chemical engineering.

Download or read book Mass Transfer written by Diran Basmadjian and published by CRC Press. This book was released on 2003-12-15 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the subject of mass transfer has been treated as a minor player in the larger field of transport phenomena and taken a back seat to its more mature "brother," heat transfer. Yet mass transfer is sufficiently mature as a discipline and sufficiently distinct from other transport processes to merit a separate treatment, particularly one that does not overwhelm readers with an abundance of high-level mathematics. Mass Transfer: Principles and Applications takes an integrated approach that uses a wealth of real-world examples, organizes the material according to mode of operation, and highlights the importance of modeling. The author begins by introducing diffusion rates, Fick's Law, film theory, and mass transfer coefficients, then develops these concepts in complementary stages. The treatment of phase equilibria covers topics generally not addressed in thermodynamics courses, and these concepts are then used to analyze compartmental models and staged processes as well as continuous contact operations. The final chapter offers a concise survey of simultaneous mass and heat transfer. Throughout the book, discussions transition smoothly between theory and practice and clearly reflect the author's many years of engineering experience and the breadth of mass transfer applications. Mass Transfer: Principles and Applications is a unique and accessible treatment of this relatively complicated topic that will fill a significant gap as both a textbook and professional reference.
