Abstract

PACT: A Course in Particle and Crystallization TechnologyAlthough many products produced by chemical manufacturers today are solids or contain solids,the training in many chemical engineering departments has little discussion of solids beyondeutectic diagrams in a materials class or a limited discussion of filtration in a chemicalengineering class. Specifically, while there is much discussion of a material’s composition,temperature, and pressure, other attributes such as particle size and shape are neglected. Whensize is discussed, frequently it is only the average size. The difficulty is that the size distributionaffects the performance of many equipment units including filters, hydrocylones, andcrystallizers. While some chemical engineering departments have developed particle technologycourses, others have not.To address this deficiency, a new survey course in Particle and Crystallization Technology(PACT) was developed that blended theory with practical applications. The goal was to provideinstruction that was not being covered in the core curriculum that would be helpful for studentsin their future careers. This course was offered twice as a split-level elective course withundergraduate and graduate students. Topics included characterization of particle size and shapedistributions, filtration, continuous and batch settling, cyclone and hydrocyclone design, particlesize reduction and enlargement, and crystallization. This course is novel in its inclusion ofcrystallization, ternary solid-liquid equilibrium phase diagrams, and population balance modelsin a particle technology course. As part of the course development, an initial version of acomputer program was developed to aid students in studying particle breakage modeling byusing population balance equations. This presentation will discuss the topics presented andresources used, as well as informal assessment of the course.
