Abstract

An elective course on chemical process separations has been developed to provide upper-level undergraduate students the opportunity to develop expertise in evaluating and potentially improving energy consumption in distillation operations. This paper presents examples of the work submitted to illustrate the pedagogy of the class. These examples examine the retrofitting of column sequences for separation, utilizing modified sequences and hardware modifications to achieve lower energy consumption, along with an economic assessment of the potential opportunities
