MINLP Optimization of Several Process Structures for the Separation of Azeotropic Ternary Mixtures

摘要

For many separation tasks in chemical industry there exists a variety of different processes to meet the desired product specifications. This paper presents a comparison between four different process alternatives for the separation of the ternary mixture methanol/2-propanol/water. To create a reliable basis for the evaluation of these different processes a rigorous MINLP optimization is carried out.
