Hello,
one of the recent threads remembered me to possess some older pictures
from a helium re-liquecation facility. I made those pictures not for
this group, but maybe you are interested.
The special aspect is the reuse of material from world war II.
I am not really sure. The containers for pressurized helium come from
underwater battleships. That's clear. Whether that are the former weapons
or containers for pressurized oxygen for a longer dive I do not really
know. Anyway, today these containers are ideally suited to store pressurized
helium.

The last picture has nothing to do with helium recovery.
Greetings
Rainer
