The discussion centers on the search for animations depicting the liquefaction process of nitrogen and helium. Users suggest that major manufacturers like BOC and Air Products may have relevant materials. The liquefaction process itself involves compressing gas, extracting waste heat, boiling off other constituents, and bottling the final product. While specific animations were not provided, it is acknowledged that such resources likely exist online.
PREREQUISITESStudents, educators, and professionals in the fields of chemistry, physics, and engineering who are interested in the liquefaction of gases and related educational resources.
mgb_phys said: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.
