Description
External reservoir providing a dead-ended blanket for fluid to the quench connection of the gland.
Features
- No direct process leakage to atmosphere.
- No need to maintain pressure system as in Plan 53A.
Use
- Preferred for clean, non-polymerizing media with vapour pressure higher than buffer fluid pressure.
Caution
- Keep pot vent continuously open, which is necessary to maintain buffer fluid pressure close to atmospheric pressure and vent the vapors to flare.
- Should not be used with dirty or polymerizing products.
- Never run the system with level in the sealant vessel at low level as marked on the level gauge.
- Vent the system properly before start up.
