In this book, the reader is guided through the complex study of dynamic chemical engineering systems by the unique combination of a simplified presentation of the fundamental theory (Part 1) and direct hands-on computer experimentation with the provision of 85 accompanying computer-based simulation examples (Part 2) supplied on diskette. The ISIM digital simulation language is very simple to use and its powerful interactive nature enables the readers to create their own simulations, based on their own specific problems. This powerful dynamic ISIM software is ready to run on any DOS personal computer. The treatment employed in this book is well tried and tested, based on over 20 years experience in teaching an international post- experience course. Whether for the teacher, the student, the chemist or engineer, this book serves as the key to a greater understanding of chemical engineering dynamics through the fun and enjoyment of active learning.
