Depressurisation time 3

[C26M13]

Hi all,

I would like to ask for advice. could anyone please advise me how to determine the time required for depressuring a vessel (low temperature vessel)?

I want to determine the time when depressure the vessel to atmospheric pressure. Below the brief description of the problem:

The design temperature of the vessel is -162 oC and the design pressure is 24 barg. the problem is when the blowdown valve (valve to dry flare) fails to open it will depressure the vessel. I want to calculate the time required to depressure the vessel to atmospheric pressure.
I am hoping to getting some advices from you.
