Azeotropic Distillation with Internal Decanters

该方案描述了一种模拟和模型化研究程序，旨在研究带内分馏器的共沸精馏塔的性质。这些塔对操作条件很敏感，在不同的塔板上显示相分离，并显示多个稳态行为。拟议的工作使用同伦连续数学技术解决了这些柱设计中的稳态问题，这些技术将被合并到用于分析这些系统的软件包中。研究的另一个仿真方面将侧重于使用软件包进行动态研究，计算时间常数和影响控制系统设计选择的其他性质，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.
