Is there a better way?
(OP)
I have a field line from a well pad to a gas treatment facility a couple of km away. The fluid is gas with a very low level of condensate/water. The line slopes constantly up towards the plant.
I would like to have an opportunity to drain liquids out of the line and would therefore like a drain vessel at the well site. The vessel shall have a design pressure=well shut-in pressure. My though is then to empty the local vessel using a truck. This is, however, a high risk operation in my view - and i have proposed an interlock system and a local vent.
My question is now: Is there a better way (apart from a dedicated full shut-in pressure return line)?
One suggestion is to pump the liquids back into the field line under operation - but this may not always be possible - and then you would still need the connection to a truck.
Any ideas?
Best regards

RE: Is there a better way?
If you have issues you can:
have a small vessel automatically dump the liquids through a level control valve to an atmospheric tank. Then just empty that tank into a truck.
You could install a blowcase system that would either go to a truck or blow case the liquids into a new smaller line that parrallels the existing line.
RE: Is there a better way?
I see your point about two vessel - the LP vessel could be fitted with PSV's for gas blow-by.
