I asked the ASME B&PV Code Committee a similar question a few years ago. My question was as follows:
Re: ASME Section VIII Division I Boiler and Pressure Vessel Code Paragraph U1(c)2(h). Can a vessel that could be excluded from the scope of the Division because it operates at pressures less...
In answer to your questions:
Yes, you need to protect both sides of the heat exchanger.
If you can show that the rupture disk is adequately sized to protect the shell side of the heat exchanger from all overpressure scenarios, then you do not need to place both a PSV and a rupture disk on the...
The equation you use to size a relief valve or calculate the capacity of a relief valve will depend upon whether the flow is all vapor, all liquid, or 2-phase. Most relief valve manufacturers provide a technical reference manual that provides the flow of vapor and/or liquid through their relief...
If the relief system contains a relief valve or relief valves and discharges to a flare, I would consult with the flare tip manufacturer to find out maximum and minimum discharge velocities. If the discharge is to atmosphere, I suggest calculating the built-up backpressure in the discharge line...
I have been told that toroidal rings are installed at the atmospheric discharge point on hydrogen relief lines to prevent static ignition. I have had no success searching the web for information on these devices or finding companies that sell these devices. Would someone please enlighten me?
I am looking for January 2000 and January 2002 "Chemical Engineering Plant Cost Indices" (CEPCI) in three subcategories. Would someone please provide the CEPCI indices (published generally on the last page in each issue of McGraw-Hill Chemical Engineering Magazine) for the following...
If you are concerned about discharge near or above the critical point, you may want to determine whether or not it is necessary to have the relief valve set so high. Lowering the set pressure of the relief valve would make sense if the set pressure is significantly above the maximum operating...
