Optimization of complex process models, e.g., those, resulting from conceptual design of distillation processes, with optimization environments such as GAMS, AMPL, or AIMMS is still thwarted by the manual implementation necessary for the interface to external thermo engines. In this contribution, we address this issue by automatically generating all code for interfacing GAMS with an external CAPE-OPEN thermodynamic property package. The distillation models in our approach are assembled in a modular way by combining multiple general vapor-liquid equilibrium stage models. A method, where all existing vapor-liquid-equilibria are relaxed is proposed and examined for enhanced model stability. The ability of our optimization approach is shown by the results of two examples that determine an optimum energy-targeted design of a fully thermally coupled dividing wall column for the separation of a zeotropic mixture of n-pentane, n-hexane, and n-heptane and an azeotropic mixture of acetone, methanol, and water.

使用 GAMS、AMPL 或 AIMMS 等优化环境对复杂过程模型（例如，由蒸馏过程的概念设计产生的模型）进行优化仍然受到外部热机接口所需的手动实施的阻碍。在这个贡献中，我们通过自动生成用于将 GAMS 与外部 CAPE-OPEN 热力学属性包连接的所有代码来解决这个问题。我们方法中的蒸馏模型通过组合多个通用汽液平衡阶段模型以模块化方式组装。提出并检查了一种放松所有现有汽液平衡的方法，以增强模型稳定性。Ñ戊烷，Ñ己烷，和Ñ庚烷和丙酮，甲醇和水的共沸混合物。
