This extensive three-volume compilation highlights the best way to separate azeotropic systems using hybrid or specialized distillation processes, such as pressure swing, azeotropic or extractive distillation. It covers practically all the data currently available for binary and higher systems, knowledge essential for the successful separation of these azeotropic systems. The sheer volume of data for more than 20,000 systems involving approximately 2,000 compounds will inspire readers. These data are carefully evaluated, documented and arranged according to molecular formula for easy access. This practical source allows the best thermal separation conditions for industry and environmental protection to be achieved. In addition to chemical engineers and physical chemists, scientists active in process engineering and environmental protection will find themselves fully equipped to deal with any separation task.
