Have seen a plant with very long dry suction line, about 300 metres, on large liquid overfeed vessel, -40 C
Vessel is well oversize for job, so very low risk of high level.
Dry suction from vessel has a few low area's in it, as it follows roof line across buildings.

At plant room before compressor suction is a slop pot/trap, with boil off coil in it.
Can anyone see that this vessel would be useful?
Changes in suction pressure, could you condense liquid in dry cold suction line & get slugs of liquid?
Thanks for any replies
