In our plant, there is a 1" rupture disk combination with a relief valve, along with a redundant unit, which is procured for gas/vapor service (i.e., fire scenario). At a few times when the rupture disk is switched to the redundant unit, the redundant rupture disk bursts as soon as it’s taken...
I have been working on a flare system to which the PSVs’ relief load due to fire scenario is exceeding the capacity of the flare system (due to an expansion in the plant). I know that using API's methodology for relief load calculation normally gives smaller relief load as compared to NFPA's...
All,
I'm currently working on reducing the relief load from a distillation column to the flare system by installation of a HIPS (or HIPPS) on the steam valve to the column. My understanding was that after installation of HIPS, I have the replace the pressure safety valve by a smaller one which...
I'm currently working on designing an absorber in Aspen Plus. For the required absorption, Aspen is telling me that I need 4 stages. Can someone guide me how to convert the 4 stages to the height of a packed bed or of a trayed column? Are there any good correlations for this purpose?
On a...
