Die Übertagung von Verfahren aus dem Labor-bzw. dem Techni-kumsmaßstab in den industriellen maßstab einer Produktiosanlage ist eine der wichtigsten ingenieurstechnischen Aufgaben in der chemischen Industrie. Die einzige zuverlässige Methode dazu basiert auf der Darstellung von Versuchsergebnissen im zutreffenden dimensions-analytischen Raum, der sich als maßstabsinvariant erweist. Das Buch ist in zwei Teile gegliedert: In der ersten Hälfte werden die vertiefte mathematische Vorkenntnisse dieses Themengebiet näherzubringen. Diskutiert werden die Grundlagen der Dimensionsanalyse, die Behandlung von temperaturabhängigen und von rheologischen Stoffwerten und die Modellübertragung bei Nichtverfügbarkeit von Modellstoffsystemen, sowie bei partieller Ähnlichkeit/ All dies wird dem leser anhand von 20 modernen Beispielen aus der heutigen verfahrenstechnischcen Praxis illustriert, der sich mit 25 in dieser Auflage neu hinzugekommenen Übungsaufgaben sein Verständnis aktive erarbeiten und anhand der Lösungen kontrollieren kann. Im zweitem Teil des Buches werden die einzelnen verfahrenstechnischen Grundoperationen aus den Bereichen mechanische, thermische und chemische Verfahrenstechnik aus der Sicht der Dimensionsanalyse und der Modellübertragung beispielhaft behandelt, und es werden für jede Operation die Maßstabsübertragungsregeln vorgestellt und diskutiert. Das vorliegende Buch wendet sich dementsprechend an Studenten wie auch bereits auf dem gebiet tätige Ingenieure, Chemiker und Verfahrenstechniker.

Contemporary Chemical Process Engineers face complex design and research problems. Temperature-dependent physical properties and non-Newtonian flow behavior of substances in a process cannot be predicted by numerical mathematics. Scaling-up equipment for processing can often only be done with partial similarity methods. Standard textbooks often neglect topics like dimensional analysis, theory of similarity and scale-up. This book fills this gap! It is aimed both at university students and the process engineer. It presents dimensional analysis very comprehensively with illustrative examples of mechanical, thermal and chemical processes.

Das Buch gibt erstmals einen Überblick über die in der metallverarbeitenden Industrie eingesetzten Chemikalien. Anwendungsbereiche, Funktionen und alle stoffspezifischen, ökologisch relevanten Informationen werden übersichtlich in Datenblättern dargestellt. Dabei sind alle relevanten Chemikalien berücksichtigt. Dem umfangreichen Datenteil ist eine Darstellung der verwendeten Chemikalien und der damit verknüpften Prozesse, einschließlich Abwasser und Abluft, vorangestellt. Mit diesen Informationen wird das Buch in der metallverarbeitenden Industrie, bei Behörden und vor allem dort sehr hilfreich sein, wo Richt- und Grenzwerte vorgegeben werden sollen oder wo Hersteller oder Verarbeiter mehr über Inhaltsstoffe und deren Umweltwirkungen wissen wollen.

Covering the important task of the scale-up of processes from the laboratory to the production scale, this easily comprehensible and transparent book is divided into two sections. The first part details the theoretical principles, introducing the subject for readers without a profound prior knowledge of mathematics. It discusses the fundamentals of dimensional analysis, the treatment of temperature-dependent and rheological material values and scale-up where model systems or not available or only partly similar. All this is illustrated by 20 real-world examples, while 25 exercises plus solutions new to this edition practice and monitor learning. The second part presents the individual basic operations and covers the fields of mechanical, thermal, and chemical process engineering with respect to dimensional analysis and scale-up. The rules for scale-up are given and discussed for each operation. Other additions to this second edition are dimensional analysis of pelleting processes, and a historical overview of dimensional analysis and modeling, while all the chapters have been updated to take the latest literature into account. Written by a specialist with more than 40 years of experience in the industry, this book is specifically aimed at students as well as practicing engineers, chemists and process engineers already working in the field.

Practical Guides in Chemical Engineering are a cluster of short texts that each provides a focused introductory view on a single subject. The full library spans the main topics in the chemical process industries that engineering professionals require a basic understanding of. They are ‘pocket publications’ that the professional engineer can easily carry with them or access electronically while working. Each text is highly practical and applied, and presents first principles for engineers who need to get up to speed in a new area fast. The focused facts provided in each guide will help you converse with experts in the field, attempt your own initial troubleshooting, check calculations, and solve rudimentary problems. Dimensional Analysis provides the foundation for similitude and for up and downscaling. Aeronautical, Civil, and Mechanical Engineering have used Dimensional Analysis profitably for over one hundred years. Chemical Engineering has made limited use of it due to the complexity of chemical processes. However, Chemical Engineering can now employ Dimensional Analysis widely due to the free-for-use matrix calculators now available on the Internet. This book shows how to apply matrices to Dimensional Analysis. Practical, short, concise information on the basics will help you get an answer or teach yourself a new topic quickly Supported by industry examples to help you solve a real world problem Single subject volumes provide key facts for professionals

This ground-breaking reference provides an overview of key concepts in dimensional analysis, and then pushes well beyond traditional applications in fluid mechanics to demonstrate how powerful this tool can be in solving complex problems across many diverse fields. Of particular interest is the book’s coverage of dimensional analysis and self-similarity methods in nuclear and energy engineering. Numerous practical examples of dimensional problems are presented throughout, allowing readers to link the book’s theoretical explanations and step-by-step mathematical solutions to practical implementations.

Physical Principles of Chemical Engineering covers the significant advancements in the understanding of the physical principles of chemical engineering. This book is composed of 12 chapters that describe chemical unit processes through analogy with the unit of operations of chemical engineering. The introductory chapters survey the concept and principles of mass and energy balances, as well as the application of entropy. The next chapters deal with the probability and kinetic theories of gases, the physical aspects of solids, the different dispersed systems, and the principles and application of fluid dynamics. Other chapters discuss the property dimension and model theory; heat, mass, and momentum transfer; and the characteristics of multiphase flow processes. The final chapters review the model of rheological bodies, the molecular-kinetic interpretations of rheological behavior, and the principles of reaction kinetics. This book will prove useful to chemical engineers.
