Semi Quantitative Risk Assessment of a Hydrogen Production Unit |
|
| چکیده انگلیسی مقاله |
The safety of hydrogengeneration facilities is the main concern in their process operation. Thisstudy was conducted to identify the hazards and evaluate the risks of ahydrogen generation plant. For this purpose, PrHA (ProcessHazard Analysis) was applied for hazardidentification while LOPA (Layer of Protection Analysis) was used for riskassessment. The study was conducted in the hydrogen production unit of BehshahrIndustrial Complex, Iran in 2011 and 2012. In the process of risk assessment, the records of the accidents and plantflow diagrams were studied. Then, the knowledge of the experts and operatorswere used through brainstorming prior to the application of LOPA technique.LOPA standard template was applied using PHA-Pro6 software. The initiatingevents, consequences, independent protection layers and probability of failurewere determined for 16 scenarios in 7 nodes. The results showed that withoutthe application of IPLs, the risks of 2 scenarios needed immediate action, 9scenarios required action at next opportunity and 5 scenarios were operational.The application of IPLs would significantly decrease the risks. The studyconcluded that LOPA has sufficient credibility for semi quantitative risk assessmentof high potentially hazardous plants. |
