LNG terminals together with industrial gas facilities require proper insulation for safety as well as stability and financial performance.
Heat Leaks: The Invisible Threat The operation of systems at cryogenic temperatures (lower than -160°C) depends on preventing even minimal heat exposure because it generates significant problems.
Insulation systems become compromised when they experience damage or improper installation or experience natural degradation leading to system heat penetration which results in immediate problems.
- Increased boil-off gas (BOG)
- Higher evaporation losses
- Unstable tank and line pressures
- Overworked compressors and safety valves
LNG tanks experience elevated pressure due to unwanted heat which requires operators to choose between flaring and venting or gas re-liquefaction processes leading to increased operational expenses and environmental effects.
Safety Risks: When Insulation Fails, Hazards Rise
The main issue with inadequate insulation goes beyond energy waste because it produces dangerous safety problems.
The storage tanks face dangerous pressure buildup when insulation fails.
- External surface icing and condensation form
- Thermal stress leads to mechanical equipment breakdown.
- Emergency venting occurs more frequently.
The combination of problems becomes more severe in high-throughput facilities when operations include load variations as well as start-ups and shutdowns.
Operational Cost Impacts Poor insulation leads to:
- Higher energy demand
- More frequent equipment maintenance
- Reduced system lifetime
- Unplanned downtimes
The use of Cryoperl expanded perlite as a high-performance cryogenic insulation material enables thermal stability and BOG reduction and safety standard compliance.
The first line of protection for boil-off and mechanical stress and operational cost control is insulation.
The prevention of future problems requires you to inspect your systems and perform maintenance and upgrades before they create balance sheet inefficiencies.
The Cryoperl company provides top-tier insulation materials that meet the needs of both LNG and industrial gas applications for safe and efficient cryogenic operations
