Thermal separation processes often account for the largest portion of the investment and operating costs in the overall process when manufacturing products and consumer goods in process engineering production facilities. Therefore, their optimal design is of great economic significance. Through over 80 tasks and design examples, the book helps to understand practical approaches in an industrial context. The step-by-step examples cover everything from the initial problem statement at the beginning of a project to thermodynamic design and fluid dynamic sizing of the equipment. In addition to pedagogically valuable paper-and-pencil methods, modern process simulation tools and practical programs for equipment sizing are also used to solve the tasks. The reader gains an understanding of where to focus their efforts.
