Azeotropic Distillation with Internal Decanters

本文提出了一种模拟和建模研究方案，旨在研究内卧螺共沸精馏塔的性能。这些色谱柱对操作条件敏感，在各种托盘上表现出相分裂，并表现出多种稳态行为。建议的工作解决稳态问题，在这些列设计使用同伦-延拓数学技术，这将被纳入软件包分析这些系统。研究的另一个仿真方面将集中在使用软件包进行动态研究，计算时间常数和其他影响控制系统设计选择的量，如右半平面零点。

This proposal describes a simulation and modeling research program aimed at studying the properties of azetropic distillation columns with internal decanters. These columns are sensitive to operating conditions, exhibit phase splitting on various trays and show multiple steady state behavior. The proposed work addresses steady-state issues in these column designs using homotopy-continuation mathematical techniques which will be incorporated into a software package for analyzing these systems. Another simulation aspect of the research will focus upon dynamic studies using software packages, calculating time constants and other quanitities like right-half plane zeros which influence the choice of control system design.
