The selection and use of computer-aided models for chemical process equipment design are stressed. The results of increasingly complex equipment and thermodynamic models are compared using the ASPEN PLUS simulation package. Students interpret the interrelationships between design and process variables using computer simulation. Simulation of systems containing solids and electrolytes is covered. Students complete an independent computer-aided design project and make an in-class presentation. Optimization methods are used to determine the best design. Prerequisites: Graduate standing in CHEN or consent of instructor. (F;S)
