Abstract

This chapter presents process synthesis (PS) and process intensification (PI) for multicomponent distillations. PS focuses on defining all the possible distillation configurations, whereas PI focuses on defining distillation systems with fewer columns. In total, seven subspaces are obtained for multicomponent distillations, each containing distinct distillation systems. A systematic synthesis procedure was developed for each subspace. Each procedure consists of distinct mechanisms and explicitly defines the physical structures of the distillation systems step by step. The systematic procedures are generalized procedures and applicable for mixtures with any number of components. The relationships of the distinct subspaces and their systematic procedures are discussed. Systematic procedures can be developed for both PS and PI in the generation of distinct distillation systems. Themethodology is a strong interplay between PS and PI for multicomponent distillation system synthesis and intensification. Therefore, a systematic synthesis procedure that integrates PS and PI is a highly efficient methodology for intensifying process systems.
