Analysis and Design of Nonideal Distillation Systems

普林斯顿大学 摘要 该项目涉及非理想分离系统的分析、设计和综合。 将使用基于吉布斯自由能最小化和切平面稳定性准则的全局优化技术。 稳定性判据将应用于具有许多组分和化学反应的系统。 目标包括确定均相和非均相体系的互变异构体，以及评价不同逸度模型和状态方程对相平衡的影响。 参数不确定性将纳入设计。 同时，将残液曲线图与最佳化方法结合，分析共沸蒸馏系统。 这些结果可能会导致改进的分离技术，用于制造化学品。

CTS - 9530651 Christodoulos Floudas Princeton University ABSTRACT The project deals with the analysis, design and synthesis of non-ideal separation systems. Global optimization techniques based on the minimization of Gibbs free energy and the tangent plane stability criterion will be used. The stability criterion will be applied to systems with many components and chemical reactions. Objectives include determination of azeotropes for both homogeneous and heterogeneous systems, and evaluation of the effects of different fugacity models and equations of state on phase equilibria. Parameter uncertainty will be incorporated into the design. Also, azeotropic distillation systems will be analyzed by combining residue curve maps with optimization methods. The results may lead to improved separation techniques for manufacturing chemicals.
