I want to simulate the opening of a PSV (buckle pin device) which is on the bypass of an MOV (upstream a two phase separator). when the MOV accidentally closes, the Buckle Pin has to open to prevent overpressurization of the upstream pipe.
In Aspen Hysys, the PSV is opening in 20 seconds minimum, which is not the real case as the buckle pin open instantaneously.
Can Aspen hysys simulate the fast opening of the PSV? or is there an extension to Aspen hysys that can be used in this regard?
Thanks
