Case Study-4
Case Study – Gas Leakage Risk Mitigation from MEG Vessel(s) to Water System
Challenge: Potential gas leakage from high-pressure system to low-pressure system leading to dangerous overpressure conditions and safety risks.
Approach:
• Evaluated multiple system configurations and presented options
• Performed hydraulic analysis and check-valve leakage calculations
• Estimated gas leakage rates under worst-case scenarios
Key Engineering Work:
• Designed PSV protection based on calculated leakage scenarios
• Ensured safe pressure relief capacity to protect low-pressure system
• Issued process datasheets for valves and PSVs to support procurement
Safety & Compliance:
• Actively contributed to HAZOP, LOPA and dispersion analysis
• Defended engineering decisions during safety reviews
Results:
• Eliminated overpressure risk due to gas leakage
• Ensured compliance with safety standards and design requirements
• Delivered practical and cost-effective protection solution
Value: Accurate engineering calculations and system understanding enabled a safe, reliable and efficient design without major modifications.
