Abstract

This paper describes a combined lecture-discussion-laboratory course for teaching students a systematic approach to process design and development. This course intends to provide students with a holistic view of process design and development by having them apply the steps required to bring a process to production in the laboratory. The course is based on books and journal articles that describe the “best practices” implementation of these techniques. The course organization, teaching strategies, and the laboratory experiments used in the course are presented.

Course Overview and Teaching Strategies

The course covers the “best practices” implementation of techniques for the efficient design and development of chemical processes. The goal of this undergraduate/graduate level course is to teach students how to bring new processes into production quickly and cheaply. At the beginning of the course, the students are assigned a process to work with (e.g., batch crystallization of a chemical). For each process, the students are given the desired characteristics of the product. By the end of the course, each student team has an optimally designed process producing the desired product in the laboratory (e.g., a batch crystallization process that produces large crystals). While the existing experimental apparatuses are based on industrial crystallization, polymerization reactions, and polymer film extrusion, the course materials are written to be sufficiently general to apply to most chemicals and materials processes.

The course includes lectures/discussions on the application of the “best practices” systematic techniques for scaling up processes, lectures/discussions on the physical basis and mathematical modeling of specific processes in the laboratory, and laboratory sections where students working in teams apply the techniques to design an optimized process (see Figure 1). The systematic techniques for process design and development include:
