'Chemical engineering is the field of applied science that employs physical, chemical, and biological rate processes for the betterment of humanity'. This opening sentence of Chapter 1 has been the underlying paradigm of chemical engineering. Chemical Engineering: An Introduction is designed to enable the student to explore the activities in which a modern chemical engineer is involved by focusing on mass and energy balances in liquid-phase processes. Problems explored include the design of a feedback level controller, membrane separation, hemodialysis, optimal design of a process with chemical reaction and separation, washout in a bioreactor, kinetic and mass transfer limits in a two-phase reactor, and the use of the membrane reactor to overcome equilibrium limits on conversion. Mathematics is employed as a language at the most elementary level. Professor Morton M. Denn incorporates design meaningfully; the design and analysis problems are realistic in format and scope.

Das Thema dieses Buches ist die ?bertragung von Verfahren aus dem Labor- bzw. dem Technikumsma?stab in den industriellen Ma?stab einer Produktionsanlage. Die einzige zuverl?ssige Methode dazu basiert auf der Darstellung von Versuchsergebnissen im zutreffenden dimensionsanalytischen Raum, der sich als ma?stabsinvariant erweist. Das Buch ist in zwei Teile gegliedert. In der ersten H?lfte werden die theoretischen Grundlagen detailliert vorgestellt, um auch Lesern ohne vertiefte mathematische Vorkenntnisse dieses Themengebiet n?herzubringen. Diskutiert werden die Grundlagen der Dimensionsanalyse, die Behandlung von temperaturabh?ngigen und von rheologischen Stoffwerten und die Modell?bertragung bei nicht-Verf?gbarkeit von Modell-Stoffsystemen, sowie bei partieller ?hnlichkeit. All dies wird dem Leser anhand von 20 modernen Beispielen aus der heutigen verfahrenstechnischen Praxis illustriert und mit 25 in dieser Auflage neu hinzugekommenen ?bungsaufgaben aktiv erarbeitet und anhand der L?sungen kontrolliert. Im zweiten Teil des Buches werden die einzelnen verfahrenstechnischen Grundoperationen aus den Bereichen mechanische, thermische und chemische Verfahrenstechnik von der Warte der Dimensionsanalyse und der Modell?bertragung beispielhaft behandelt und es werden f?r jede Operation die Ma?stabs?bertragungsregeln vorgestellt und diskutiert. Das vorliegende Buch wendet sich dementsprechend an Studenten wie auch bereits auf dem Gebiet t?tige Ingenieure, Chemiker und Verfahrenstechniker.

Hier ist es endlich - das Buch über CFD, das sich nicht nur an die Programmentwickler, sondern an Anwender in der Industrie wendet. Verfahrensingenieure, die CFD als Werkzeug einsetzen, werden darin gebündelt das Maß an Informationen finden, das Ihnen das Verständnis für ihre spezifischen Anwendungszwecke erleichtert. Enthalten sind auch Themen, die Sie in anderer Fachliteratur nicht oder nur am Rande finden, wie z.B. mehrphasige Systeme und Populationsbilanzen. Computational Fluid Dynamics (CFD) ist ein in der industriellen Praxis zunehmend verbreitetes Werkzeug zur effizienten, material- und kostensparenden Entwicklung von Apparaten und verfahrenstechnischen Komponenten. Dabei geht es um die Bearbeitung strömungsmechanischer Fragestellung mit Hilfe numerischer Simulationsverfahren. Hierfür stehen kommerzielle Programme zur Verfügung, deren Hintergrund der Anwender in der Industrie nicht im Detail, aber im Prinzip kennen muss.

In this book, the modelling of dynamic chemical engineering processes is presented in a highly understandable way using the unique combination of simplified fundamental theory and direct hands-on computer simulation. The mathematics is kept to a minimum, and yet the nearly 100 examples supplied on a CD-ROM illustrate almost every aspect of chemical engineering science. Each example is described in detail, including the model equations. They are written in the modern user-friendly simulation language Berkeley Madonna, which can be run on both Windows PC and Power-Macintosh computers. Madonna solves models comprising many ordinary differential equations using very simple programming, including arrays. It is so powerful that the model parameters may be defined as "sliders", which allow the effect of their change on the model behavior to be seen almost immediately. Data may be included for curve fitting, and sensitivity or multiple runs may be performed. The results can be seen simultaneously on multiple-graph windows or by using overlays. The resultant learning effect of this is tremendous. The examples can be varied to fit any real situation, and the suggested exercises provide practical guidance. The extensive experience of the authors, both in university teaching and international courses, is reflected in this well-balanced presentation, which is suitable for the teacher, the student, the chemist or the engineer. This book provides a greater understanding of the formulation and use of mass and energy balances for chemical engineering, in a most stimulating manner. This book is a second edition, which is much improved by the new software, and it also includes a new section on biological process examples.

Chemical separations are of central importance in many areas of environmental science, whether it is the clean up of polluted water or soil, the treatment of discharge streams from chemical processes, or modification of a specific process to decrease its environmental impact. This book is an introduction to chemical separations, focusing on their use in environmental applications. The authors first discuss the general aspects of separation technology as a unit operation. They also describe how property differences are used to generate separations, the use of separating agents, and the selection criteria for particular separation techniques. The general approach for each technology is to present the chemical and/or physical basis for the process and explain how to evaluate it for design and analysis. The book contains many worked examples and homework problems. It is an ideal textbook for undergraduate and graduate students taking courses on environmental separations or environmental engineering.
