Plan 76 (Gas Leakage Collection Panel)
Buffer/Barrier
Plan 76 is a system to divert non-condensing primary seal leakage to a flare or vapour recovery system.
Why do we use it?
- When an arrangement 2 plan is required
- When the process fluid entirely vaporises after leaking across the inboard seal
- When a vent/flare system is available
Advantages:
Lower initial and maintenance costs than dual unpressurized seals using a Plan 52.
General:
Plan 76 can be used in conjunction with a gas purge from Plan 72.
