Liquifaction of Nitrogen/Helium

[avinash1968]

Dear Friends,
I want to explain the liquifaction of Nitrogen/Helium. Does anyone has a short movie related to this? or can I download from some site.

Do you mean a video of it being manufactured - that is probably just going to show a lot of pipes and clouds of water vapour.
Big makers are BOC and AirProducts, they may have some material.
Or do you mean an animation of gas molecules being cooled - I don't have any but there probably are some on the net.

It's not very complicated, compress gas, extract waste heat, boil off the other consituents, bottle, sell.

Thanks for your reply. I mean just an animated film and not the one with lot of pipes and clouds
