As per my understanding you don't need to depressurize till 0.2 kg/cm2g within 15 min, limit depressurization upto 3.5 kg/cm2g in 15 min.

Hello Breizh

 

Is there any procedure / calculation you are aware of for depressurizing a vessel containing liquid (water). We have pressure vessel operating at 110 barg, for maintenance we would like to isolate the vessel and reduce the pressure to atmospheric. Any input would help!

Hi  ADR,

Sorry I cannot help , let see what others have to say.

Open the drain to release the water from the vessel. What's the problem?

Hi,

Can you share with us a PID or PFD ?

How big is the tank? Do you have way to drain it and release the pressure ?

Do you have past experience performing the task ?

thanks in advance.
