An Instruction Module on Hybrid Separations for Undergraduate Chemical Engineering Separations Courses In industry, chemical engineers are often enlisted to retrofit equipment and/ormodify operations to achieve increased production capacity, increased productpurity and/or improved energy efficiency. In undergraduate chemical engineeringseparations courses, the focus is on stand-alone separation processes such asdistillation, gas absorption/stripping, and extraction. At some universities,membrane-based processes are included in the traditional separations course. Itmay be advantageous to couple two separation processes to achieve a superiorseparation sequence in terms of operating costs and/or capital expenditures.Separation of an azeotropic mixture using distillation alone requires theintroduction of an extractive solvent or an entrainer, either of which much berecovered and recycled. The benefits of hybridization in separations are realizedfor the separation of azeotropic mixtures using distillation and pervaporation. Aninstructional module developed for hybrid separations will be presented in thispaper.
