Generally PSV's are needed for code reasoms - so you may elimnate the scenario as described, hvorever the blow-by vase may not be your worst case? Wrt SIL remember that its not only about getting the gadgets - they also needs to be serviced and teststed. For SIL 3 you will have to test quite...

I think NFPA is for dust? But maybe also for gasses? Anyway, for dust the NFPA must be added to the operating pressure - so unless yout reactor is operating at ATM it should be safe for containing an explosion. I dont know wrt a detonation though at George mentions.

would probably do as shvet describes: "As a "shortcut" in such cases I sometimes practice installing a smallest PSV with no a credible scenario behind that. This can't be called "sound engineering".

Hi Big, You need to know stuff about thermodynamics specificalle for steam! Or get someone you know (and preferrably pay) to tell your. You get good advice here but if something is wrong are you just going to say "well the guys at this website said...."? Anyway, also check out checalc. They...

Bronze is one of the substances that will last the longeste exposed to the elements. I dont know if there is a special "sculpture" mix but you might be able to find out yourselve. --- Best regards, Morten Andersen

note that this will not be legal in EU in my understanding of PED and the PED FAQ's --- Best regards, Morten Andersen

your local legislation may limit the evaporation. This may require vapor recovery and/or low storage temperature. --- Best regards, Morten Andersen

@OP in my opinion yes, because its a throttling process with a (almost) constant enthropy - but as other has mentioned in a regular refrigeration system you would get condensated refrigerant after the valve flooding the area that you want cooled (may be a "radiator" might be pipes with a cooling...

Its your engineering system (and MOC system). You should ask a colleague not some random dude. --- Best regards, Morten Andersen

Depends on the amount of soilds, but a mag pump seems like a good alternative. You dont want your boiling 80% acetone to leak too much --- Best regards, Morten Andersen

I think it might be relating to your components. One of them might not have the nhv defined, and then it cant calculate it for the entire phase. If im right you can propably specify it (guess / estimate e.g. based om MW and compare to other components. If its a low fraction it might not matter...

... sounds like there's going to be a shortage of metallurgical PEs? ;-) --- Best regards, Morten Andersen

i think your problems will be with any elastomers. Check this first. BUT you could have tried good ol' google, this was at the very top (for metals and alloys): https://www.methanol.org/wp-content/uploads/2016/06/Compatibility-of-Metals-Alloys-in-Neat-Methanol-Service.pdf and this was the...

@ FPPE, You can find many PED category calculator on the net e.g. this: https://www.hpivs.ie/ce-certification-2/ped/pressure-vessel-calculator I would think that liquid sulphur is liquid group 1. If your pressure is in absolute bars then its not covered by PED --- Best regards, Morten Andersen

Maybe the most accurate thing would be to measure it in a test bench? --- Best regards, Morten Andersen
