The framework is based on a three-step approach consisting of (1) variant generation, (2) screening of all variants based on shortcut methods, and (3) the final detailed design by means of rigorous optimization. Different approaches for the generation of distillation flowsheets and the analysis of inherent limitations are presented and compared in the context of a qualitative and quantitative assessment of split feasibility. An elaborate overview on different shortcut methods for the evaluation of distillation process performance is given, and their applicability to the design of azeotropic distillation processes is discussed. Since rigorous optimization should always follow shortcut-based design and evaluation steps, recent advances in this field with a focus on azeotropic distillation are highlighted. The chapter closes with the presentation of a few example case studies for the conceptual design of different types of azeotropic distillation processes.enAzeotropic distillationConceptual designCurved-boundary distillationExtractive distillationFinite refluxHeteroazeotropic distillationPinch distillation boundaryPressure-swing distillationShortcut methodsSimple distillation boundarySplit feasibilityTotal reflux and reversible distillationTotal reflux distillation boundaryJournal Article10.1016/B978-0-12-386547-2.00008-9Other
