PSV Sizing Software
(OP)
What PSV Sizing software do most people use and what are your comments on it?
We currently use Farris SizeMaster but are looking to upgrade to a program with more capabilities (modify discharge coefficients, backpressure calculations with multiple relieving valves, etc.) We often do PSV sizing verifications of existing systems so we need a program that is catered to different valve manufacturers, services, and configurations.

RE: PSV Sizing Software
However, you also have standalone independent tools out there. I think Aspen has some cool tools. I have used SuperChems in my area. It is a very flexible but does require some good training before you can really be efficient. You can build your PSV and layout and modify characteristics as needed. I have attached the link below. Notice how the program is advertised as being able to handle various types of evaluations. It is a powerful tool but I feel the flexibility in applications is what also creates the a somewhat steep leaning curve.

RE: PSV Sizing Software
I suggest to use the search option in eng-tips forum, there are many posts discussing PSV sizing (single phase, two-phases etc.) with different methods and formulations as well as design criteria,
many manufacturers distribute software for PSV design / rating, these can include procedures according API 520 / ISO 4126, for two phase (non-reacting) a common option is Omega method (included in Farris),
the mentioned Design Institute for Emergency Relief Systems (DIERS) provides several good tools if you are interested in process analysis (rather than PSV rating/sizing)
to answer your question, for PSV datasheets (including automatic design / rating) I have found useful Excel with Prode Properties (which includes several PSV models for single and two-phase as HEM, HNE, HNE-DS plus fluid properties)
with Office you can easily create data-sheets and use a software for calc's.
