529-0580-00L | Risk Analysis of Chemical Processes and Products | O | 4 credits | 3G | K. Hungerbühler | |
Abstract | Scientific methods for characterization of risks and environmental impacts of chemicals. | |||||
Objective | Basic understanding for methodology of Process Risk Analysis, Product Risk Analysis and Life Cycle Assessment. | |||||
Content | Central to this lecture is the characterization of risks and environmental impacts of chemicals (from both production and application) by means of Process- and Product Risk Analysis as well as Life Cycle Assessment. Emphasis is put on scientific methods and their problem-oriented application in the field of chemical process and product technology. Contents: Qualitative and quantitative methods of risk characterization by means of modeling and by comparison of (1) probability and consequences (short-term scenarios) and (2) exposure and does-effect relationship (long-term scenarios); use of molecular structure and physicochemical substance properties as descriptiors of substance-specific hazard indicators regarding mobility, persistence, toxicity, fire/explosion, etc.; derivation of conceptual design criteria for inherent safety and eco-efficiency in chemical process and product systems; sensitivity and uncertainty analysis | |||||
