Mixed-Integer Optimization of Distillation Column Tray Positions in Industrial Practice

摘要

We present an outer approximation algorithm tailored to the optimization of distillation column feed and side draw tray positions. A new fallback rule based on a generalization of an integer cut for integer parameters is presented. This fallback rule turned out to be a key ingredient to successful application to real-world problems. As an example, a process design optimization of an natural gas treatment plant is presented.
