Occupational and environmental hazards and an engineer’s responsibility for the safety of the community are the main focus of this module. Case studies and several different techniques for analyzing hazards are discussed. Unit topics include:
- |
System safety engineering |
- |
System safety techniques |
- |
Preliminary design of metal organic chemical vapor deposition |
- |
Preliminary design of an ethylene production plant |
- |
Preliminary design of an alkylation process |
- |
Preliminary design of a high pressure/low density polyethylene plant |
- |
The batch process of industrial and military explosive production |
- |
Instructor’s guidelines |
Possible courses for integration: Design, Seminar
Case studies and examples:
| A | Case study: “Preliminary Design of an Ethylene Production Plant.” This case study emphasizes FTA and PHA analysis of the plant. Results of the analyses are discussed. |
| B | Case study: “Preliminary Design of an Alkylation Process.” System safety techniques are used to evaluate an alkylation process. An event tree analysis is used, as is cause-consequence analysis. |
| C | Case study: “Preliminary Design of a High Pressure/Low Density Polyethylene Plant.” System safety techniques including “what if” analysis and hazard and operability study (HAZOP) are used to evaluate the HPLD polyethylene plant. |
| D | Case study: “The Batch Process of Industrial and Military Explosive Production.” “What if” analysis and PHA are applied to the nitrocellulose manufacturing process. |
| E | Example problems: Eight problems are found at the back of this module. These problems involve applying system safety techniques including fault tree analysis, preliminary hazard analysis, HAZOP, event tree analysis, “what if” analysis, and failure modes, effects, and criticality analysis. |
