Transport Mechanisms In Membrane Separation Processes

de J.G.A. Bitter

DISPONIBILIDADE IMEDIATA

 The present book contains a comparison of existing theoretical models developed in order to describe membrane separation processes. In general, the permeation equations resulting from these models give inaccurate predictions of the mutual effects of the permeants involved, due to the simplifications adopted in their derivation. It is concluded that an optimum description of transport phenomena in tight (diffusion-type) membranes is achieved with the "solution-diffusion" model. According to this model each component of a fluid mixture to be separated dissolves in the membrane and passes through by diffusion in response to its gradient in the chemical potential. A modified Flory-Huggins equation has been derived to calculate the solubility of the permeants in the membrane material. Contrary to the original Flory-Huggins equation, the modified equation accounts for the large effect on solubility of crystallinity and elastic strain of the polymer chains by swelling. The equilibrium sorption of liquids computed with this equation was found to be in good agreement with experimental results. Also, the sorption of gases in both rubbery and glassy polymers could be described quan- titatively with the modified Flory-Huggins equation without any need of the arbitrary Langmuir term, as required in the conventional "dual-mode" sorption model. Furthermore, fewer parameters are required than with the at least identical accuracy.

Reaction Engineering Of Step Growth Polymerization

59,61€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The literature in polymerization reaction engineering has bloomed sufficiently in the last several years to justify our attempt in putting together this book. Rather than offer a comprehensive treatment of the entire field, thereby duplicating earlier texts as well as some ongoing bookwriting efforts, we decided to narrow down our aim to step growth polymerization systems. This not only provides us the lUxury of a more elaborate presentation within the constraints of production costs, but also enables us to remain on somewhat familiar terrain. The style and format we have selected are those of a textbook. The first six chapters present the principles of step growth polymerization. These are quite general, and can easily be applied in such diverse and emerging fields as polymerization applications in photolithography and microelec tronics. A detailed discussion of several important step growth polymeriz ations follows in the next five chapters. One could cover the first six chapters of this book in about six to eight weeks of a three-credit graduate course on polymerization reactors, with the other chapters assigned for reading. This could be followed by a discussion of chain-growth and other polymeriz ations, with which our material blends well. Alternately, the entire contents of this book could be covered in a course on step growth systems alone.

Engineering Flow And Heat Exchange

de Octave Levenspiel

95,40€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This volume presents an overview of fluid flow and heat exchange. In the broad sense, fluids are materials which are able to flow under the right conditions. These include all sorts of things: pipeline gases, coal slurries, toothpaste, gases in high-vacuum systems, metallic gold, soups and paints, and, of course, air and water. These materials are very different types of fluids, and so it is important to know the different classifications of fluids, how each is to be analyzed (and these methods are quite different), and where a particular fluid fits into this broad picture. This book treats fluids in this broad sense including flows in packed beds and fluidized beds. Naturally, in so small a volume, we do not go deeply into the study of any particular type of flow, however we do show how to make a start with each. We avoid supersonic flow and the complex subject of multiphase flow where each of the phases must be treated separately. The approach here differs from most introductory books on fluids which focus on the Newtonian fluid and treat it thoroughly, to the exclusion of all else. I feel that the student engineer or technologist preparing for the real world should be introduced to these other topics.
