I have a model that drifts a bit from my initial settings. Instead of going back to steady state to reinitialize I would just like to set the values.
I put a stream off by itself and specified the composition, temp, and pressure. I used this stream to initialize other streams. I had to do it...
Very helpful, and thank you, this calculation is confirming what I was afraid of. My case is isothermial flash. The solution is both iterative, and a very large number of equations for a mixture of say 10-12 components.
I need determine the ratio of liquid to gas, of a flashing LNG mixture. I'm using Peng Robinson EOS, and I cannot use HYSYS, refprop, or any external tool to Excel. I have the flash calculation working, so I have all fugacitys and relative composition of liquid and vapor for all components...
Latexman,
To me, it actually does address safety by giving facility requirement in order to avoid dangerous situations (flame restorers are required when flash is <100F). Question is whether or not safety is fully covered by the standard, perhaps. Would NFPA30 be the right answer (beyond...
Can a liquid with a flash point at 0[C], but RVP around 3[psia] go to an open drain system? According to API2000, it seems our atmospheric tanks can handle the liquid provided that they meet some venting requirements (flame arrestor, etc), but its unclear if this liquid can be drained from...

Question: So I have seen this scenario a few times in my career, but would like to better understand what a pressure vessel...
It cannot be hydrolock in this case. The liquid that is fed to the blower as "seal oil" is actually from a knock out put just downstream of both vacuum pumps. Therefore, unless a very large slug somehow got into the blower, it could only (at steady state) recirculate what is being knocked out...
Yes this is a roots type vacuum blower.
What are the symptoms of too much liquid?
If the liquid changes phase from upstream to downstream of the blower what are the symptoms, and does this cause damage.
Thanks,
Theron
Have a vacuum blower just upstream of a liquid ring vacuum pump that is failing. We inject seal oil just upstream of the vacuum booster blower for the purposes of sealing/cooling. This liquid that we are using as "seal oil" is actually from the knock out pot just downstream of the liquid ring...
bigInch,
I have seen these terminal management softwares (specifically the one that Honeywell sells), but this is not the type of problem I am trying to solve (at the moment). The problem I have now is... do we build 10 new dock lines, or can we get away with 1 dock line, and flush after every...
Thanks BigInch. You never cease to amaze me.
It will take me some time to digest all of this information, and determine if I can relatively easily apply it to this scenario (as DIY). I'll have to revert.
Thanks,
Theron
We are expanding a terminal to account for a processing facility that we are building. There are some areas that we can save money by combining long lines to docks/rail/truck loading (with multiple different product loading streams) at the expense of product quality / line cleaning.
