The Siting, Process Analysis and Design of a Manufacturing Facility Using Hazardous Materials in a Residential Community (The Manufacture of Aspirin) is a joint cooperative project by Faculty from the Departments of Chemical Engineering, Chemistry and Environmental Sciences, and Civil and Environmental Engineering to introduce freshmen to design concepts and problems. The chemical engineers focus on the process analysis and design concepts while the civil engineers focus on facility siting and related problems, including visits to potential sites, environmental restrictions, political reservations, economic aspects related to the site, and final site selection and plant layout. The chemical engineers are concerned with the process concept, hazardous material and health considerations, input-output flow rates, material balances around the process and the process units, estimating the size of the manufacturing plant, raw material requirements, and pollution abatement and prevention. This workbook follows the concept of a freshman chemistry laboratory workbook and is developed to guide the inexperienced students, step by step, through the process analysis of an aspirin manufacturing process. it is suggested that the students work through the workbook, as teams, with each other for a meaningful learning experience.
