I need to know from you if it is possible to send ethylene liquid at -100C with a 22 km pipeline.
What are the difficulties and design requirements to be implemented to do this transfer.
Thank you
Best regards

RE: Ehylene transer
This does not seem typical or practical over such a distance. More usual is vapor or supercritical ethylene. Once your liquid is pumped up to pressure and warmed to ambient, you can still recover alot of refrigeration value when you cool and let it back down (if that is the reason you wish to transport at -100C).

RE: Ehylene transer
It seems you have experience on this
Can you give further explanation of your reply
It is intended to send liquid ethylene from an atmospheric tank at -100C to a jetty at a port. The distance between the tank and the port is about 22km.
What do suggest
Thank you
RE: Ehylene transer
My experience is with higher pressure USA gulf coast ethylene distribution, ethylene manufacture, and safe handling of ethylene in general. I am hopeful you will get some more useful replies now that the destination and purpose are better understood.
My comment about impractical is related to pipeline insulation, metallurgy, pipeline start-up/shutdown, vapor recovery, and other items which are generally non-issues with long pipeline ambient temperature transfers. I will make speculative further comments if you don't get some other replies.
in the meantime, best wishes as always, sshep
