Model-Based Design & Operational Optimization of Distillation Systems

This presentation covers model-based design and operational optimization of continuous distillation processes. Distillation is the most frequently used unit operation for separations. Despite decades of simulation, many distillation columns remain thermodynamically inefficient as well as costly to build and operate. Recent developments in equation-based modeling allow for major advances in distillation optimization, including optimal feed tray location and number of stages. The presentation demonstrates the model-based design using case examples including ethylene production, air separation units, propylene oxide production, Petlyuk columns and whole plant optimization including both the reaction and separation sections.
