Available in PDF, EPUB and Kindle. Book excerpt: Over-all mass transfer coefficients were determined independently of the interfacial area by considering the operation of the pulse column to be a stage- wise process. The calculated coefficients describe only the operation of the pulse column for the free rise of organic droplets through a stage, since in the downstroke the aqueous phase passes through the organic phase in the form of rivulets preferentially wetting the plates. The driving force for transfer was based on the aqueous phase concentrations. The mass transfer coefficient was found to increase when the interfacial tension was reduced. Two factors appear to affect the mass transfer coefficient as the pulse frequency is changed and are: a) recycle or backmixing which tends to decrease the coefficient through a reduction of acetic acid in both phases and thereby increases the interfacial tension, and b) turbulence which enhances the coefficient by reducing the continuous film resistance. The first is important at or near the lower flooding limit, but the latter is the controlling factor at higher frequencies. (D.L.C.).

This book was released on 1983 with total page 700 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of "mass transfer with chemical reaction" takes place whenever one phase is brought into contact with one or more other phases not in chemical equilibrium with it. This phenomenon has industrial, biological and physiological importance. In chemical process engineering, it is encountered in both separ ation processes and reaction engineering. In some cases, a chemical reaction may deliberately be employed for speeding up the rate of mass transfer and/or for increasing the capacity of the solvent; in other cases the multiphase reaction system is a part of the process with the specific aim of product formation. Finally, in some cases, for instance "distillation with chemical reaction," both objectives are involved. Although the subject is clearly a chemical engineering undertakin, it requires often a good understanding of other subjects, such as chemistry and fluid mechanics etc., leading to publications in diversified areas. On the other har.d, the subject has always been a major field and one of the most fruitful for chemical engineers."

Download or read book Extraction '84 written by Sam Stuart and published by Elsevier. This book was released on 2013-09-03 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extraction '84 presents the proceedings of the Symposium on Liquid–Liquid Extraction Science, held in Dounreay, Scotland, on November 27–29, 1984. This book discusses the principle involved in liquid–liquid extraction. Organized into 22 chapters, this compilation of papers begins with an overview of the performances of pulsed columns, including decontamination factors and recovery yields. This text then discusses the alternative ways of managing neptunium in the Purex process and reviews the main coordination and redox characteristics of neptunium in nitric medium. Other chapters consider the mass transfer measurements made in a pulsed plate liquid–liquid extraction column. This book discusses as well the extraction of uranium from wet process phosphoric acid. The final chapter deals with full-scale pulse column tests, which have been performed with uranium and simulated fission products to evaluate. This book is a valuable resource for chemical engineers, chemists, chemical physicists, and research workers.

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: The mineral resources of the industrialized countries, especially the member nations of the North Atlantic Treaty Organiza tion, are being depleted at such a rate that more and more of these count ries are beginning to depend on ore imported from other coun tries. To sustain the economic and strategie well-being of these member countries, it becomes imperative that a program of developing and exploiting other non-conventional mineral resources and a con servation program where metal values from waste dumps and scrap metals and alloys are recycled must be initiated and implemented. In order to meet this challenge, new processes and technology must be available for consideration in the design and operation of the new plants. One of the possible routes of extracting the metals from their ores, especially for multimetal complex ores and very low grade ores, is by hydrometallurgical processing. The hydrometallurgical route of metal recovery where dissolution (leaching), separation and concentration (ion exchange, solvent extraction, and membrane separation) and reduction to metal (cementation, precipitation by gaseous reduction, and electrolysis) is carried out at near ambient temperature is becoming more competi tive with the conventional high temperature processes used in the smelting of metals from high grade and beneficiated ores.
