I am looking to desigtn and simulate a vertical pressure vessel holding 10 m3 of pressurized Liquid Propane Gas (LPG) by following the American Society of Mechanical Engineers (ASME) standard for the design. The pressure vessel in this study is cylindrical with two elliptical heads, two nozzles, a manway and four legs support. I have seen different publications where is not clear about applying the pressure. In some publication is mentioned that they apply hydrostatic pressure and other normal pressure or both.
Any idea, suggestion or recommendation will be much appreciated.
Hi,
you should use design pressure for numerical simulation plus the hydrostatic pressure of the liquid. Design pressure is a conventional number that is greater than or equal to working pressure. For this case, I guess working pressure shall be at least the saturated pressure of LPG or a few kPa higher.
