Your best bet is to find one from a different project.
But if you want to start from scratch first work out how many you need. Easiest is to do them for each flange rating you have.
You need a venting and relief study to determine the maximum relief load. For methanol it's probably a fire relief case.
Your process designers should be giving you this information. M
Short answer is no.
Longer answer is that any pump or compressor you need to know certain things in order to size it or buy it.
These are
Fluid and it's properties (density, MW, compressibility, heat capacity etc)
Inlet conditions (pressure, temperature)
Outlet requirements (pressure mainly...
Not really sure how anyone really expects you to do this "fresh out of college".
VFDs in particular are complex things at times and you can't just copy the last one we did.
what resources / people do you have available?
What access to company procedures / training / guideline?
What access to...
Not everything is in a close which generally provides the MINIMUM that you sound so. What you do is up to YOU.
A large number of weld you can take a percent approach which can vary from the minimum to 100%. A single weld is up to you. If your question is whether a flange weld is any different...
Lengths, pressures, temperature in the different sections would be useful as well as any slopes.
That section between steam trap offtake and the valve and then the downstream section.is important.
Something that would be good maybe is how to use all the waste heat conventional systems throw away at 40, 50, 60, 70C using some of the newer chemicals.
Perhaps sit down with himnad break it down into both the stages of the project - concept, design, procurement, construction, safety/risk, commissioning and operation and then also the component parts - boiler, piping, steam motor, generator, control system, electrical components and then discuss...
"and maybe sometimes attended by Shell staff."
Hence why they want someone that knows what they re looking at and whether it is being done correctly or not.
I'm no flange designer here, but I would have thought that what you want to do is have the O ring groove machined in both sections to the correct depth so that when the two metal parts are then clamped together with (much) more force and torque than you are proposing, the O ring is compressed...
I forgot to ask what the operating pressure was.... They look like pretty mighty bolts so is this a class 900 or more?
As with any repair or plugging, removal of rust and "gunk" can increase the leakage rate a lot or result in a jet of liquid, so shutdown or drain down should be the first...
