Normally chemists tend to be too anxious with regard to chemical engineering methods (and the mathematics involved); in contrast, engineers often feel uncomfortable if chemical aspects have to be examined and gain prominence. This textbook integrates the four disciplines of chemical technology: chemistry, thermal and mechanical unit operations, chemical reaction engineering and general chemical technology for students of both chemistry and chemical engineering, and is organized into two main parts: - The fundamentals of chemical technology as well as the analysis and design of industrial processes - The presentation of 20 industrial processes and their design, exemplifying the inherent applied nature of Chemical Technology. Supplemented by a small general survey of selected modern trends such as multifunctional and micro reactors or new solvents for homogeneous catalysis such as ionic liquids, it will certainly convince the reader that this is not a concluded discipline, but a developing field with great challenges still waiting for future generations to solve. The philosophy of this work can be best expressed through Einstein's words: "Everything should be made as simple as posible but not simpler".
