Liquefaction of neon with turboexpander

Neon is liquified under medium pressure by cooling it through indirect heat exchange with liquid nitrogen after which it is divided into a minor portion which is turboexpanded and used as the basic cold source to cool the remainder of the medium pressure neon, which latter is finally throttle expanded to effect liquefaction. The use of a turbo expander for the liquefaction of neon is more advantageous than the use of hydrogen and helium, as in the first case the sound velocity is small, which offers the possibility to realise the cycle with isentropic expansion of the gas without the known shortcoming inherent to ram expansion mechanics.
