The proposed research concerns the development of tools to analyze and design separation processes using the mass transfer modeling approach. These tools allow one to identify multiple steady states in distillation column models, an important piece of information in control system design. In addition, one of the problems faced in developing distillation flowsheets for separating non-ideal mixtures is coming up with feasible sequences for the flowsheet. These are not obvious, especially in highly non-ideal systems and the concept that is to be used here involves calculating residue maps for the system. As part of this proposal the PI has developed a plan to do experimental work, including a planned collaboration with Bacardi Corporation, to complement his theoretical work studying the existence of multiplicities in azeotropic systems. The research is intended to focus upon non-equlibrum models, the equilbrium case having been more completely studied in the prior literature in the field.

拟议的研究涉及开发使用传质建模方法分析和设计分离过程的工具。 这些工具允许人们识别蒸馏塔模型中的多个稳态，这是控制系统设计中的重要信息。 此外，开发用于分离非理想混合物的蒸馏流程图面临的问题之一是提出可行的流程图顺序。 这些并不明显，特别是在高度非理想的系统中，并且这里要使用的概念涉及计算系统的残差图。 作为该提案的一部分，PI 制定了一项实验工作计划，包括计划与百加得公司合作，以补充他研究共沸系统中多重性存在的理论工作。 该研究旨在集中于非平衡模型，平衡案例在该领域的先前文献中已得到更全面的研究。
