Can any body help me to find vendor/manufacturer of gas dehydration unit which uses tethra ethilene glycol or dipropelene glycol as liquid absorbent.

Put a coalescing filter upstream of the contactor to keep the oil out. Make sure your glycol is a few degrees warmer than the gas. This should stop the oil in the TEG.
The issue is most likely that you have more pounds of water to remove at the lower pressure. This means you need more circulation rate and more reboiler.
I'm not so sure about TrEG having a greater dew point depression unless you can get it's purity a lot higher. Dew point depression is a function of the glycols purity at the top stage more than anything else.
RE: Tethraetylene glycol gas dehydration units
Thaks for rplay , all answers make me think again and i really appreciate your help.
RE: Tethraetylene glycol gas dehydration units
The rebolier duty goes from 5.5 MMBTU/hr to 7.2 MMBTU/hr. This will be true for TEG or TrEG. Are you sure your reboiler is big enough too?
RE: Tethraetylene glycol gas dehydration units
About reboiler. Heater never was loaded even up to 75% of load. And glycol purity is higher than 99.7%.
Thanks Dcasto you helped me so many times that I need to give you a star for this. Thanks to everybody in this thread.
RE: Tethraetylene glycol gas dehydration units
You mentioned in order to increase oil production you reduced the pressure. Can you please explain me how an increase oil production happens when we reduce the pressure
