This particular design is as you say run as a two-phase separator followed by heating then liquid-liquid separation. Still i'm surprised that liquid-liquid separation occurs when done in a cold 3-phase LTS separator, similar mixtures exist in gas reception facilities for instance were glycol is...
Re the observations on HTFS i also notice it predicts a whopping 3x increase in pressure drop with glycol. You may think thats overinjection - i've set the rate to give 2 to 3wt% average dilution of the glycol to ensure operations are maintained in the safe concentration region.
On a slightly...
Thanks maddocks, you’ve obviously got a lot of good experience in this area.
To follow up on some of your advice...
Tube plugging is certainly an option available for planned shutdowns . Not sure on its usefulness in this instance as the production profile is relatively rapid ascent and...
I'm looking for some guidance on designing MEG glycol injected gas-gas exchangers for gas turndown on an LTS, say 5 to 1.
Minimum tube gas velocities of 12-15ft/s are recommended in thread124-70137 and elsewhere to provide good dispersion through the tubes.
The turndown of these exchangers is...
