Managing process plants that use high-temperature organic heat transfer fluids (HTFs) requires careful design, construction and maintenance to ensure safety and reliability.
The extreme conditions in these systems come with risks — particularly leaks, which most often occur at flanged connections, flexible connectors, rotary joints and pump seals. Such leaks can pose fire hazards if not properly managed.
Best practices to reduce leak risk include:
- Design piping systems with enough flexibility to prevent stress on gaskets and flanges.
- Use fire-resistant gaskets and proper sealing techniques.
- Implement regular maintenance and inspection programs.
- Employ advanced leak detection methods such as photoionization instruments and remote video monitoring.
In the event of a leak, understanding the fire triangle — oxygen, ignition source and fuel — is key to preventing a bad situation from getting worse. Strategies to break the triangle and minimize fire risk include using inert gas blanketing, installing ignition source control and designing a robust system.
Emergency response measures can further enhance safety. Measures can include knowing how to practice remote isolation, installing water-fog mist suppression, training personnel and keeping firefighting equipment nearby.
By combining sound design principles with proactive maintenance and advanced monitoring, operators can reduce the frequency and impact of HTF leaks, ensuring safer, more efficient plant operations.
