Rupture disc location on batch reactor
Rupture disc location on batch reactor
(OP)
Hi community!
I am working in a chemical plant which produces resins in batch mode in reactors.
Most of the reactors are protected by a rupture disc located on a dedicated line on top of the vessel.
Some of them are also protected by a rupture disc but the location is different and I am not 100% confident on this location.
Please refer to the attached file: the rupture disc is located on a line that is connected to the reactor through a vent line by a tee.

My question is: do this connection is acceptable? I don't see any recommendation on API 520.
Cheers,
Kevin

To a ChE, the glass is always full - 1/2 air and 1/2 water.

The issue of polymerization in the rupture disc line can be a serious one or a trivial one depending on which "resins" you're making. In the case that the rupture disc shares the vent, you will at least know when that line is plugged, but of course you'll be in big trouble on that day! You will also be carrying monomer in the vent gas past the rupture disc where, depending on the monomer system, it might condense and polymerize over time.
The best option is a flush-mounted (so-called "extruder style" rupture disc which is flush with the inner surface of the top head.

The rupture disc(PSE) often be equipped with relief valve(PSV) if the discharge fluid is viscous or corrosive. It is installed before the PSV intended to block the viscous or corrosive fluid to enter the PSV to increase the PSV downstream back pressure if system overpressure occur.
Some consideration in locating this PSE is near the operation and maintenance access to operator and prevent any liquid seal formation which would obstruct the relief flow to the system.
Hope this is make sense.
