Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1922 edition. Excerpt: ...the more volatile component than the liquid with which it mixes, thereby increasing the proportion of volatile component on the top plate. Continuing, as the composition of the liquid on the top plate increases in the more volatile component, the effect will be felt on the plate below, and after the distillate from the condenser has been returned to the column for a considerable length of time, the effect will be that all of the plates in the upper portion of the column will contain substantially nothing but the more volatile component. When this condition has been reached, if the valve leading from the condenser to the receiver for distillate is then opened, the first portion of vapor which comes over will be that liquid which has collected on the plates in the upper portion of the column and will, therefore, be practically pure component. When the contents of the column have distilled over in this manner, there will be a sudden break in the composition of the distillate and when this break occurs, the fraction is shifted and a small intermediate fraction is then recovered in a separate distillate receiving tank. If this method of complete reflux of the distillate were not practiced, the amount of intermediate fraction between any two pure fractions would be very greatly increased. In the same way, when the benzene has been nearly all distilled over, it is possible to obtain a sharp cut between the benzene and the toluene fractions by refluxing completley for a certain length of time. There will be, of course, a small intermediate fraction consisting of a mixture of benzene and toluene and this intermediate fraction must be returned and mixed with the next charge which is put into the kettle and redistilled. The net capacity of any...

Book Description
Elements of Fractional Distillation By CLARK SHOVE ROBINSON AND EDWIN RICHARD GLLLILAND. PREFACE TO THE FOURTH EDITION: This book and the early revisions were the result of the efforts of Professor Robinson, and he took an active part in guiding the revision of the previous edition. His death made it necessary to prepare this edition without his helpful guidance and counsel. The present revision differs extensively from the previous edition. The material has been modified to bring it more closely into line with the graduate instruction in distillation at Massachusetts Institute of Technology. Much greater emphasis has been placed on the measurement, prediction, and use of vapor-liquid equilibria because it is believed that this is one of the most serious limitations in design calculations. Greater emphasis has also been placed upon the use of enthalpy balances, and the treatment of batch distillation has been considerably expanded. Unfortunately, the design calculations for this type of operation are still in an unsatisfactory status. Azeotropic and extractive distillation are considered as an extension of conventional multicomponent problems. The sections on column design and column performance have been completely rewritten and increased in scope. In all cases quantitative examples have been given because it has been found that this greatly aids the student in understanding descriptive material. During the last 15 years a large number of design methods have been proposed for multicomponent mixtures, some of which are reviewed in Chapter 12. Most of these do not appear to offer any great advantage over the conventional Sorel method, and it is believed that the law of diminishing returns has been applying in this field for some time. It is hoped that the present edition will stimulate some of these investigators to transfer their efforts to more critical problems, such as vapor-liquid equilibria, batch distillation, transient conditions within the distillation system, and column performance. EDWIN RICHARD GILLILAND CAMBRIDGE, MASS. July, 1960. PREFACE TO THE FIRST EDITION: The subject of fractional distillation has received but scant attention from, writers in the English language since Sidney Young published his book Fractional Distillation in 1903 London. French and German authors have, on the other hand, produced a number of books on the subject, among the more important of which are the following La Rectification et les colonnes rectificatriccs en distillerie, E. Barbet, Paris, 1890 2d ed., 1895. Der Wirkungsweise der Rcctificir und Destillir Apparate, E. Hausbrand, Berlin, 1893 3d ed., 1910. Theorie der Verdampfimg und Verfliissung von gemischcn und der fraktionierten Destination, J. P. Kuenen, Leipzig, 1906. Theorie der Gewinnung und Trennung der atherischen Olc durch Destination, C. von Rechenberg, Leipzig, 1910. La Distillation fractione e et la rectification, Charles Manlier, Paris, 1917. Youngs Fractional Distillation, although a model for its kind, has to do almost entirely with the aspects of the subject as viewed from the chemical laboratory, and there has been literally no work in English available for the engineer and plant operator dealing with the applications of the laboratory processes to the plant. The use of the modern types of distilling equipment is growing at a very rapid rate. Manufacturers of chemicals are learning that they must refine their products in order to market them successfully, and it is often true that fractional distillation offers the most available if not the only way of accomplishing this...
