High pressure trip on reactor setting
High pressure trip on reactor setting
(OP)
Hello all,
One very quick query please.
We have a high pressure trip on reactor set at 12barg which stops the reactor reactor pump.
Once the reaction is completed, reactor is depressurised to atmospheric pressure and then vacuum of say 800mbara is applied.
There was a discussion that our instrument department would loop out the high pressure trip when reactor is at the vacuum stage.
My query is
As the high pressure trip is set at 12barg, this trip will not be activated when the reactor is at vacuum and hence no need to loop out anyways. Is my understanding correct or am I missing anything?
Thanks in advance.

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

HiCompositepro,
Thanks. Yes, that could be the reason - i will double check. Just one correction though - that looping out might be due to preventing the high pressure switch exposure to vacuum and not other-way round.
