Modeling And Analysis of Chemical Engineering Processes
About this eBook
Preface Globalization has changed the world. Our world faces unprecedented changes. The Chemical Industry is one of the foundations of our civilization, since hardly any branch can survive without innovation. The Chemical process industry faces serious problems with regard to new materials and efficient methods of production due to increasing costs of energy, stringent environmental regulations and global competition. To tackle these is complex enough and it needs a clearer understanding of the processes themselves. One of these is to understand the process clearly through a crisp modeling method. Another is to improve profitability and efficiency through an optimal operation of the process itself. In this book, which is in two parts, the first one discusses the methods of modeling chemical engineering processes through well known mathematical methods with numerical calculations. This includes the recent concepts of Fuzzy logic and neural nets. In the second, the three chapters describe the efficient optimization methods which are available for the effective application to many a chemical process. This involves methods of search for extrema as well as optimization with and without constraint relations. In this book, a number of problems of choice have been worked out. Additionally computer programs are included for almost all the topics. Most books on nonlinear programming are of a theoretical type and the exact procedures of computation are often obscure. The optimization programs are very intricate and having provided the flow charts and the program in clear BASIC language for easy readability, the reader can exactly understand the mathematical methods. In a book of this kind, which has gleaned information and help from various sources like books, journals and also the internet, it is difficult to acknowledge each one individually. The authors are thankful to all these, including help rendered by students. Further the second author wishes to acknowledge the assistance of the AICTE in the course of writing the book by providing him an emeritus fellowship. Authors
