Describe in detail the process plant and identify the storage facility
The module coursework requires you to develop a HAZOP study and a Quantitative Risk Assessment (QRA) study on a chemical storage facility. The QRA study has to be completed using Singapore QRA guidelines. For simplification purpose, consider modelling only for catastrophic rupture of all equipment, a single weather condition and wind direction. Any other assumptions made in the QRA study should be clearly stated and justified in the report.
Chapter 1: Description of the process unit/storage facility.
Describe in detail the process plant and identify the storage facility. Draw and describe the pipeline and instrument diagram and provide the equipment count for it. The chemical chosen must be acute hazards, either flammable or toxic. Describe about the process unit/storage facility and must include a Process and Instrumentation Diagram (P&ID). Ensure that the chemicals considered are either flammable and/or acutely toxic.
This places the emphasis on rare but potentially catastrophic events. Chronic effects such as cancer or other latent health problems should not be considered in the QRA. The careful definition of scope and depth of study in the application of QRA is crucial to success because it is costly and resource intensive. The site location in google map including the site plan and coordinates of this location must be provided.
Chapter 2: Hazard Identification
Perform a HAZOP study on the storage facility using the below guidewords. Use chemical hazard assessment and Hazard and Operability Study (HAZOP) study to identify the major accident hazards and explain how various initiating causes can be realised into loss of containment scenarios.
