Compare visiting a corporate or university library; or a technical book store. Few US Engineering standardards are available online for free. Numerous ASME standards exist including many updates. You may find information regarding the latest standard and perhaps update issues. Corporate...
Some of us lack most chemical engineer details; some like dcastro may cover for us - or correct us. I will keep my head down for his corrections. ;-)
Natural gas from a gas well or especially an oil/gas well are likely saturated. A chryogenic gas plant may drop the temperature below -150...
Things change. Separate contacts, DCS and SIS signals may apply. Different companies split the control responsibilities. Some SIS bypass functions may be permitted with continuoun alarm and regular refreshment. Industry requirements frequently vary. Advise the process and some may advise...
Pressure drop is a significant different between restriction and flow orifice data. Perhaps 100 inch water is common for liquid orifice drop and lower with vapors. If a pump raises 100 psig, the restriction orifice on the reccycle drops about the same. Plate should be thicker etc.
Some process applications vary on P&ID details. Variations exist among process and client differences. OSHA 1910.119 applies to hazardous applications, Details differ among process types for the P&ID control and other aspects. Some reflect a control scheme with auto/manual etc. with the...
Perhaps inlet head pressure too low, temperature high, tight rotating turns etc. could cause suction flashing. Cavitation and flashing could share similar features.
I might forget some situations. It may be common for some to isolate flow, pressure, level trandmitters with the manifold valve etc. Offline instrumentation is not significant. Perhaps fes temperature thermowells would be bothered; unless initiating a major steamout exceeding the calculation...
Consider a few sulfur related compounds ... hydrogen sulfide, thiosulfates, mercaptans - more; for example. Some 40 CFR 60 series or international standards suggest envirnmental interest -- total flow, BTU, sulfurs, N2, C..., etc. Perhaps sample taps, returns, utilities, etc. in flaring system...
I wonder, could air and hydrocarbon possibly ignite and not just explode? Perhaps something like commissioning and checkout folks know a bit about nitrogen, CO2 or other compounds to be inert in lieu of to be explosive, perhaps.
Flanges exclude the # symbol ASME B16.5. Different pressure and temperature tables apply to different metals. Materials in groups 1.1 (A 105 or A 216 WCB CS) and 1.2 (A 350 and A216 WCC) will be high compared to others. I notice that I lack the 2009 standard on my home PC. Still, chrome...
