Two Phase Relief Valve Design

[Samiran]

Hi all,

Anybody has any info on how to design for 2-phase relief. I am aware of the HEM and HNEM models but any worked out example will be extremely helpful.

Thanks in advance to all respondees.

API 520 Part 1 latest revision (2000) Appendix D reveal the detail design calculation for the 2-phase relief scenario taking into account the omega factor etc.

API- 520/521 is the first step. As this is very generic, if you have specific problem/ confusion then you can discuss that seperatly.
