摘要

The separation network synthesis (SNS) is a major research field of process synthesis. A separation network comprises separators, mixers, and dividers, collectively called operating units, through which multi-component streams flow while being processed. Various combinations of the operating units, usually give rise to a multitude of complex networks. The aim of SNS is to combine operating units so that the resultant network generates the desired products with the lowest possible cost. A procedure for generating rigorous super-structures is proposed herein. The objective of the current work is to solve SNS problems in which the candidate separators are affected by different mechanisms. Such mechanisms are always based on different physical or chemical properties of the components to be separated, e.g., volatility, solubility, permeability, adsorptability, and density. The majority of SNS methods, however, takes into account only a single property, mainly the volatility. The current work introduces a novel algorithmic method for generating the super-structure and the related mathematical-programming model for a class of SNS problems, which involves any number of components, feeds and products and the available separators can be based on different mechanisms. For simplicity, the separators are regarded to be of the simple and sharp type, and the cost of a separator is linear. The efficacy of the algorithm is illustrated by an on-line demonstration.
